No one in the small Maharashtra village had computers or phones. Only one household owned a television, and neighbors often gathered there to watch shows together.</p><p>Ingole never even saw a computer growing up. It wasn’t until he reached middle school that he encountered a computer lab, an experience he says changed his life. Almost immediately, he says, the machine felt like a window into a different scale of possibility for him.</p><h3>Balaji Ingole</h3><br/><p><strong>Employer </strong></p><p><strong></strong>Amla Commerce in Milwaukee</p><p><strong>Title </strong></p><p><strong></strong>Project manager</p><p><strong>Member grade</strong> </p><p>Senior member</p><p><strong>Alma maters </strong></p><p><strong></strong>COEP Technological University and Welingkar Institute of Management, both in India</p><p>“I was very studious and not very social, always reading or solving problems in a math textbook,” he says. “At the computer lab, I began learning the <a href="https://www.c-language.org/" rel="noopener noreferrer" target="_blank">C programming language</a>—which was like discovering a whole new world. I was fascinated that you could create something with just a few lines of code.”</p><p>His early interest grew into a self-directed education. Outside of Ingole’s formal classwork, he taught himself to build database-backed applications, wire up hardware, write software, and trace error logs.</p><p>Today the IEEE senior member similarly splits his time. During the week, he’s a project manager in Milwaukee at B2B e-commerce company <a href="https://www.amla.io/" rel="noopener noreferrer" target="_blank">Amla</a>, leading AI-driven digital transformation initiatives to help the company’s clients boost their sales. On weekends, he leads a similarly demanding life as an independent researcher. His current projects include developing AI-enabled health care diagnostic tools and assistive technologies to support people with physical disabilities.</p><p>“I believe in ‘learn by doing,’” he says. “I really like to test my knowledge and prototype ideas to find out if they truly work.”</p><h2>A college project becomes an inspiration</h2><p>Ingole’s tendency to go beyond his coursework continued after he graduated high school in 2004. As a mechanical engineering undergraduate at <a href="https://www.coeptech.ac.in/" rel="noopener noreferrer" target="_blank">The College of Engineering, Pune (now COEP Technological University)</a>, in India, he participated in several extracurricular activities. One was interviewing entrepreneurs and writing about them for <em><em>The COEP College Magazine</em></em>. The experience helped him gain confidence, he says, giving him the push he needed to pursue interviews for the publication with two Indian entrepreneurs he admired: <a href="https://www.infosys.com/about/management-profiles/narayana-murthy.html" rel="noopener noreferrer" target="_blank">N.R. Narayana Murthy</a>, cofounder of IT giant <a href="https://www.infosys.com/" rel="noopener noreferrer" target="_blank">Infosys</a>; and his wife, philanthropist <a href="https://sudhamurty.in/" rel="noopener noreferrer" target="_blank">Sudha Murty</a>. The Murtys cofounded the <a href="https://www.infosys.org/infosys-foundation.html" rel="noopener noreferrer" target="_blank">Infosys Foundation</a>, a nonprofit that runs educational, health care, women’s empowerment, and sustainability <a href="https://www.infosys.org/infosys-foundation/initiatives.html" rel="noopener noreferrer" target="_blank">programs</a> in underserved areas of India.</p><p>“Every week I would fax them: ‘Please give me an interview time,’” Ingole says. Eventually, Sudha Murty’s office offered him a phone interview, but he requested to meet her in person at Infosys’s Bengaluru offices. She agreed, but the offices were 940 kilometers from Pune, and he didn’t have the money to travel or stay overnight in a hotel.</p><p>Ingole and a classmate borrowed money from friends and traveled through the night on multiple buses and trains to get to Bengaluru. They freshened up in a public bathroom before heading to the Infosys campus to meet Murty.</p><p>Impressed by their persistence, she surprised them by also arranging a brief chat with Narayana Murthy.</p><p>“Narayana Murthy handwrote a personal message to the engineering students of [my college]—which we proudly published in our college magazine,” Ingole says. “In his note, Murthy shared that we are at an extraordinary moment in India’s history and that the future looks even brighter. His words encouraged us to work hard and make the most of this time.</p><p>“I still have that note,” Ingole says. “They are billionaires, and I was just a regular student. The fact that they took the time to do this really motivated me.”</p><p>During the final semester of his engineering studies, Ingole joined the <a href="https://in.linkedin.com/company/tata-research-development-and-design-centre-trddc" rel="noopener noreferrer" target="_blank">Tata Research Design and Development Center</a> in Pune for a six-month internship. After earning his bachelor’s degree in mechanical engineering in 2008, he became a graduate engineering trainee at <a href="https://automation.honeywell.com/us/en" rel="noopener noreferrer" target="_blank">Honeywell Automation</a> in Pune.</p><p>He left the company in 2009, and during the next 13 years, he held different software engineering and project management positions at IT companies across India.</p><p>He earned a master’s degree in business administration from the <a href="https://www.welingkar.org/" rel="noopener noreferrer" target="_blank">Welingkar Institute of Management, Mumbai,</a> in 2017.</p><p>In 2022 he accepted a project-manager role at <a href="https://marssg.com/" rel="noopener noreferrer" target="_blank">Mars IT Solutions in Madison, Wisc.</a> The following year, he left to join <a href="https://www.gainwelltechnologies.com/" rel="noopener noreferrer" target="_blank">Gainwell Technologies</a>, also in Madison, as a senior project manager. At Gainwell, he managed projects for the core IT systems multiple U.S. state health departments use to administer <a href="https://www.medicaid.gov/" rel="noopener noreferrer" target="_blank">Medicaid</a> benefits, manage provider enrollment, and verify member eligibility. The experience managing projects that directly enabled patients’ access to health care gave Ingole a special appreciation for and interest in this area, he says.</p><p>“Health care data is not like other data,” he says. “The stakes are high, compliance requirements are different, and the margin for error is effectively zero.”</p><p>Ingole says he enjoyed the rigor of data governance combined with the potential to positively impact lives, and that also applies to his current work at Amla.</p><h2>Agentic AI in e-commerce</h2><p>Ingole joined Amla in July 2025. He helps manufacturers and B2B customers modernize their <a data-linked-post="2650248208" href="https://spectrum.ieee.org/who-invented-ecommerce" target="_blank">e-commerce</a> operations. He also builds AI tools for them and for his internal team.</p><p>For Amla’s customers, he’s developing AI-enabled chatbots that help manufacturers set up and manage large product catalogs in e‑commerce platforms. Such product setup traditionally has been a manual, tedious, error-prone process: Companies upload thousands of products, adjust item names, enter prices, update images, and more.</p><p>“Product setup has been one of the most painful processes in e-commerce, and it can take [our] customers two to three months to complete,” Ingole says. “We’re creating an AI agent that will guide them, step-by-step, to get everything set up in two weeks.”</p><p>Ingole relies on AI agents for some of his own tasks at Amla. Project managers historically have spent 10 to 12 hours each week assembling and sending status reports to stakeholders. Ingole built an AI agent to handle much of the work.</p><p>“It runs every Monday morning and reads through my emails to extract highlights, risks, timelines, and upcoming releases, then sends me a written status report,” Ingole says. The process might sound simple, but the agent’s workflow involves at least a dozen steps including defining parameters, managing temporary files, and integrating with existing tools.</p><p>With the information-gathering work handled, it frees up Ingole and his colleagues to spend more time on deeper-thinking work, he says.</p><h2>Publishing as idea refinery</h2><p>For nearly a decade, Ingole has spent some of his free time conducting independent research projects in data analytics and AI-enabled applications in health care. He has written <a href="https://ieeexplore.ieee.org/author/790405442038687" rel="noopener noreferrer" target="_blank">more than 40 peer-reviewed papers</a>, which are in the <a href="https://spectrum.ieee.org/free-access-to-thousands-of-covid19-research-documents" target="_self">IEEE Xplore Digital Library</a>. He has been granted six patents in the United Kingdom and India. In the U.K., he is a registered coinventor of an AI-powered, cloud-connected <a href="https://www.researchgate.net/publication/388234716_AI-POWERED_CLOUD-CONNECTED_WEARABLE_DEVICE_FOR_PERSONALIZED_HEALTH_MONITORING" rel="noopener noreferrer" target="_blank">wearable device for health monitoring</a> and an <a href="https://www.researchgate.net/publication/389874948_AI-BASED_BREAST_CANCER_DETECTION_DEVICE" rel="noopener noreferrer" target="_blank">AI-based breast cancer detection tool</a>.</p><p>Ingole’s patent for the breast cancer detector, he says, reflects his belief that when engineers apply data and AI correctly, they can help doctors diagnose patients more quickly and accurately.</p><p>That, he says, is both a power and a responsibility.</p><p>He is part of a team helping patients who are paralyzed and nonverbal control items in their environment. His goal, he says, is to develop a brain-computer interface to let patients turn on a fan, switch off a television, and complete similar tasks.</p><p>Publishing research requires both academic rigor and peer scrutiny, and Ingole says the function has been critical to improving as both a project manager and a researcher-inventor.</p><p>“Lots of research ideas never make it to paper,” he notes. “But when you write for journals or conferences, you’re bombarded with questions from Ph.D.s and experienced researchers. This forces me to refine my methodology, and to combine use cases and technical architecture in a way that stands up to expert review.”</p><h2>Finding a professional hub</h2><p>Ingole joined IEEE in 2022, and he says the affiliation has become central to both his research and his professional identity.</p><p>“I use the <a href="https://cis.ieee.org/activities/membership-activities/ieee-member-directory" rel="noopener noreferrer" target="_blank">Member Directory</a> often and contact engineers through my IEEE email address, which gives me credibility because they know it’s a genuine research connection,” he says.</p><p>The organization has given him a platform to contribute to the research space beyond his own papers, he says. He has served as a conference session chair, keynote speaker, technical program committee member, and peer research reviewer for various conferences and events. His IEEE membership, he says, has opened doors to other communities, helping support his entry into the <a href="https://www.bcs.org/" rel="noopener noreferrer" target="_blank">British Computer Society</a>, which has stringent acceptance criteria.</p><p>Those opportunities have helped him build a global network of collaborators with whom to discuss upcoming research, seek advice, and share data, he says.</p><p>“IEEE is important for me to continue as an independent researcher,” he says. “It lets me contribute to the community, and I get a lot in return.”</p>]]></description><pubDate>Fri, 21 Aug 2026 18:00:01 +0000</pubDate><guid>https://spectrum.ieee.org/ieee-senior-member-ai-ecommerce</guid><category>Ieee-member-news</category><category>Artificial-intelligence</category><category>E-commerce</category><category>Careers</category><category>Type-ti</category><dc:creator>Julianne Pepitone</dc:creator><media:content medium="image" type="image/jpeg" url="https://spectrum.ieee.org/media-library/a-professionally-dressed-indian-man-smiling-with-a-trophy-in-one-hand-and-an-award-certificate-in-the-other.jpg?id=67657769&amp;width=980"></media:content></item><item><title>Stop Hunting, Start Solving: Accelerating Root Cause Analysis with Agentic AI</title><link>https://event.on24.com/wcc/r/5460332/DAFEFF7A68EE900DEA7A14356089B553?utm_source=IEEE&amp;utm_medium=site&amp;utm_campaign=922</link><description><![CDATA[

Your coworkers encourage you to move forward because they believe it could be the organization’s next big success. The idea clearly falls outside your department’s responsibilities, however, and you have no role in the product line.</p><p>What should you do? Sit and wait for “the right group” to pick it up, or push the idea forward without knowing how or what it might mean for your current position?</p><p>Such situations occur frequently. Many end up as missed opportunities, even though they could have significantly advanced the company’s technological or market position.</p><p>Some organizations actively support such initiatives, allocating specific periods during the workday for employees to focus on developing their own ideas.</p><p>Companies known for that include <a href="https://about.google/company-info/" rel="noopener noreferrer" target="_blank">Google</a> and <a href="https://www.3m.com/" rel="noopener noreferrer" target="_blank">3M</a>. They allow employees to pursue projects with a portion of their time, such as one day per week. <a href="https://onlinelibrary.wiley.com/doi/10.1111/caim.12309" rel="noopener noreferrer" target="_blank">Research</a> that I conducted indicates it pays off for employee performance.</p><h2>Bootlegging and skunkworks</h2><p>At some companies, managers know such projects exist, but they deliberately turn a blind eye, allowing them to continue.</p><p>Some employees persist through bootlegging or skunkworks projects.</p><p>Bootlegging projects have not been approved by a manager or funded by the company.</p><p>Skunkworks projects involve a small team within the company that has been given authority and funding to secretly research and develop potentially groundbreaking innovations during their off-hours. The term comes from <a href="https://www.lockheedmartin.com/en-us/who-we-are/business-areas/aeronautics/skunkworks.html" rel="noopener noreferrer" target="_blank">Lockheed’s Skunk Works</a> division, set up in 1943 in a rented circus tent to build the P-80 fighter jet in secret. It took just 143 days.</p><p>The 3M <a href="https://en.wikipedia.org/wiki/Post-it_note" rel="noopener noreferrer" target="_blank">Post-it Note</a> came out of the company’s “15 percent culture,” described as a permitted bootlegging policy. It gives employees paid time off to pursue their own ideas.</p><p>The company traces the philosophy to its longtime president and later chairman <a href="https://www.nytimes.com/1978/03/05/archives/william-l-mcknight-who-built-a-sandpaper-company-into-3m-from-the.html" rel="noopener noreferrer" target="_blank">William L. McKnight</a>. Company scientist <a href="https://en.wikipedia.org/wiki/Arthur_Fry" rel="noopener noreferrer" target="_blank">Arthur Fry</a> used the policy in 1974 to turn a colleague’s dormant adhesive into the first Post-it prototypes, after his own bookmarks kept falling out of his hymnal.</p><p>There are several examples of high-visibility skunkworks projects. At <a href="https://www.apple.com/supply-chain/" rel="noopener noreferrer" target="_blank">Apple</a>, <a href="https://spectrum.ieee.org/steve-jobs" target="_self">Steve Jobs</a> pulled roughly 20 people—<em><em>pirates</em></em>, as he called them—out of the company to build the original <a href="https://spectrum.ieee.org/apple-macintosh" target="_self">Macintosh</a> computer in a building nicknamed Texaco Towers. In <a href="https://en.wikipedia.org/wiki/Walter_Isaacson" rel="noopener noreferrer" target="_blank">Walter Isaacson</a>’s biography <a href="https://www.amazon.com/Steve-Jobs-Walter-Isaacson/dp/1451648537" rel="noopener noreferrer" target="_blank"><em><em>Steve Jobs</em></em></a>, he frames the idea as modeled on the skunkworks approach.</p><p><a href="https://support.google.com/mail/answer/56256?hl=en" rel="noopener noreferrer" target="_blank">Google’s Gmail</a> system is frequently—and incorrectly—cited as a product of the company’s “20% time” policy. In a 2014 <a href="https://time.com/43263/gmail-10th-anniversary/" rel="noopener noreferrer" target="_blank">interview</a> with <em><em>Time</em></em> magazine, the system’s creator, <a href="https://en.wikipedia.org/wiki/Paul_Buchheit" rel="noopener noreferrer" target="_blank">Paul Buchheit</a>, said Gmail was in fact an official assignment. What the Gmail incubation did share with classic skunkworks projects was secrecy: For much of its three years in development, it was kept hidden from most people inside the company.</p><p class="pull-quote"><span>If you want to drive change in your organization, build a promoter triad around your idea.</span></p><p><span></span>At <a href="https://abc.xyz/" target="_blank">Alphabet</a>, Google X—now known simply as <a href="https://x.company/" rel="noopener noreferrer" target="_blank">X</a>—operated as a secretive “<a href="https://www.entrepreneur.com/science-technology/8-of-the-coolest-projects-to-come-out-of-x-googles/326836" rel="noopener noreferrer" target="_blank">moonshot</a>” lab, kept hidden from most Google employees, according to a 2011 <a href="https://www.nytimes.com/2011/11/14/technology/at-google-x-a-top-secret-lab-dreaming-up-the-future.html?_r=1" rel="noopener noreferrer" target="_blank">article</a> in <em><em>The New York Times</em></em>. Google’s self-driving car project graduated from X to become <a href="https://waymo.com/" rel="noopener noreferrer" target="_blank">Waymo</a>, and <a href="https://x.company/projects/glass/" rel="noopener noreferrer" target="_blank">Google Glass</a> was likewise incubated there. The X team is now developing the second edition of <a href="https://developers.google.com/glass-enterprise" rel="noopener noreferrer" target="_blank">Glass Enterprise</a>, a successor aimed at industrial rather than consumer use.</p><p><a href="https://developers.google.com/glass-enterprise" rel="noopener noreferrer" target="_blank">Amazon</a> runs a comparable model through <a href="https://www.amazon.jobs/content/en/teams/devices-and-services/lab126" rel="noopener noreferrer" target="_blank">Lab126</a>, which, according to an <a href="https://www.fastcompany.com/3040383/following-fire-phone-flop-big-changes-at-amazons-lab126" rel="noopener noreferrer" target="_blank">article</a> in <em><em>Fast Company</em></em>, evolved from a small skunkworks Amazon subsidiary into a hardware maker with nearly 3,000 employees. Lab126 delivered the <a href="https://www.amazon.com/kindle/" rel="noopener noreferrer" target="_blank">Kindle</a> in 2007 and the <a href="https://www.amazon.com/alexa/shop-echo-devices" rel="noopener noreferrer" target="_blank">Echo</a> in 2015.</p><p>Then there are so-called <em><em>submarine projects</em></em>, which employees work on without permission and despite explicit disapproval. They can lead to disciplinary action and termination. </p><h2>Innovation management</h2><p>Innovation management theory offers a more structured and robust approach. It argues that successful organizational change requires support at several levels, according to “Teamwork for Innovation: The ‘Troika’ of Promoters,” published in <a href="https://onlinelibrary.wiley.com/journal/14679310" rel="noopener noreferrer" target="_blank"><em><em>R&D Management</em></em></a>. The promoter theory, developed around 25 years ago, consistently shows that change projects are far more likely to succeed when they are supported on multiple organizational levels. A good idea alone is not enough; you need a network of technology, process, and power promoters to turn a concept into a fully implemented, scalable solution.</p><p>First, you need a technology promoter: the person who has the idea, such as a new product, and possesses technical expertise and specific knowledge about the field or industry. Art Fry at 3M would be such an individual.</p><p>How can you put that into practice as an individual? Start by clearly formulating your idea into a concise concept paper or one-page summary including benefits, technical feasibility, and potential business impact.</p><p>Identify potential technology promoters (experts who can validate and refine your idea), and approach them early to strengthen the technical foundation.</p><p>In parallel, map the relevant stakeholders and decision-makers, and identify process promoters who understand how decisions are made in your company. They could be colleagues in innovation, R&D, or business development who understand your idea and how it can benefit the company.</p><p>The second is a process promoter: someone who might not know all the technical details but understands the organization’s formal and informal networks and knows how to navigate its processes, committees, and decision-making paths. This person can ensure the idea reaches the right stakeholders at the right time.</p><p>In the 3M case, it would be a person from the organizational management department, often called an <em><em>innovation manager</em></em>. The key role here is to connect inventors such as Fry with people from other departments needed for further project development, such as manufacturing, quality control, and sales.</p><p>Lastly, there’s the power promoter: a person in a leadership position who might not know the technical details but can allocate resources, eliminate obstacles, and maneuver through the company’s political dynamics. This individual has hierarchical power and acts as a sponsor of the idea or project. In the case of Fry, the person could be, say, the chief technology officer, but it also could be a middle manager who has the power for an individual field of action.</p><p>The three-level promoter structure applies regardless of whether the change concerns a new product, new service, or internal process innovation.</p><p>Engage potential power promoters by presenting a low-risk, small-scale pilot and a clear value proposition. Leaders are more likely to support ideas that are well prepared, vetted for potential risks, and backed by a small coalition. </p><h2>Building the promoter triad</h2><p>In short, don’t work in isolation. Systematically build alliances across expertise, networks, and hierarchical levels to create lasting change. If you want to drive change in your organization, build a promoter triad around your idea.</p><p>The tech experts and leadership promoters are easier to identify. Process promoters are often found in corporate innovation management, R&D management, or strategy functions, but they also can emerge in line units with strong internal networks.</p><p>Innovation management, as the promoter model describes it, looks nothing like the management structure most engineers are trained to expect. Traditional technical management runs on a single reporting line. With the promoter model, influence is spread across three people—technology, process, and power promoters—who may be in different departments, at different levels of seniority, and who might never share a reporting line.</p><p>What holds the trio together isn’t a formal structure; it’s the idea itself, for as long as it takes to move the idea forward.</p><p>That makes innovation management closer to networked, matrix-style leadership than to the pyramid most engineers picture when they hear the word <em><em>management</em></em>. It’s worth understanding both models before you decide which kind of impact you’re actually optimizing for.</p><p><em><em>The Institute</em></em> has covered the tension from the individual’s side in “<a href="https://spectrum.ieee.org/thinking-like-an-entrepreneur" target="_self">Tips for How to Think Like an Entrepreneur</a>,” “<a href="https://spectrum.ieee.org/management-versus-technical-track" target="_self">Management Versus Technical Track</a>,” both published in partnership with the <a href="https://www.ieee.org/membership-catalog/productdetail/showProductDetailPage.html?product=MEMTEM014" rel="noopener noreferrer" target="_blank">IEEE Technology and Engineering Management Society</a>, and “<a href="https://spectrum.ieee.org/ic-or-manager" target="_self">What to Consider Before You Accept a Management Role</a>” from the <a href="https://spectrum.ieee.org/files/81653/careeralert-06-02-25.html" target="_self"><em><em>IEEE Spectrum</em></em> Career Alert</a> newsletter. All are worth a look if you’re weighing a formal management track against staying close to the technology itself.</p><p>Remember: You don’t have to build your promoter network alone or only inside your own company.

Many of the disabilities affect independence and mobility.</p><p>Three high school students working on inventions to help people with disabilities restore movement, translate thoughts, and navigate rough terrain had their work showcased at Regeneron’s <a href="https://www.regeneron.com/responsibility/fueling-stem-innovators/isef" rel="noopener noreferrer" target="_blank">International Science and Engineering Fair (ISEF)</a>, held in May in Phoenix. Their projects earned them this year’s <a href="https://www.ieee.org/education/preuniversity/scholarship" rel="noopener noreferrer" target="_blank">IEEE Presidents’ Scholarship</a> awards.</p><p>IEEE President <a href="https://spectrum.ieee.org/u/maryellen-randall" target="_self">Mary Ellen Randall</a> presented the awards at a <a href="https://youtube.com/watch?v=HW1uGgQk_7U" rel="noopener noreferrer" target="_blank">ceremony</a> held during the fair. They also received an IEEE President’s coin, which students said was a highlight of their experience.</p><p>Hollie Tang won this year’s IEEE Presidents’ Scholarship of US $10,000 for her <a href="https://isef.net/project/sftd046-tonguage-tongue-based-hmi-for-motor-disabilities" rel="noopener noreferrer" target="_blank">wheelchair navigation system</a>.

Using tongue movements and a standard camera, the interface lets users control a computer and other digital tools as well as assistive technologies including wheelchairs. The tongue pad, one of the system’s core features, allows the user’s tongue to function as a directional cursor, while eye blinks serve as mouse clicks.</p><p>Tonguage translates the person’s tongue and eye motions into actionable commands in several ways, such as the tongue’s position inside the mouth and continuous movement patterns. The system’s multimodality combines input from the tongue with other facial cues.</p><p>The system includes a face-tracking feature for error prevention that verifies commands are coming from the intended user, disregarding anyone else who moves into the camera’s frame.</p><p>That is a critical safety measure for a wheelchair-navigation application, Tang says.</p><p>Accessibility was central to Tang’s mission. She built the system to run on relatively affordable, readily available laptop cameras rather than more costly specialized hardware.</p><p>“Mobility conditions don’t discriminate,” she says. “They can affect anyone of any income, gender, and socioeconomic status.”</p><p>Tang initially imagined Tonguage as a simple substitute for a keyboard and mouse. The more research she did, though, the more she realized that it could offer autonomy through applications such as wheelchair navigation, robotic arm control, and gaming, she says.</p><p>“We’re so focused on trying to give people autonomy over just basic human tasks that we often leave out things like gaming,” she says. “They deserve the freedom to play games and enjoy entertainment as well.”</p><p>Tang, who plans to pursue biomedical engineering, says a visit to a rehabilitation center solidified her purpose.</p><p>“Including empathy in your technological solution is so important,” she says. “Empathy is hard to teach in a classroom, but it can be learned through experience, and through actually meeting people whose lives your work might change.”</p><h2>Mind-controlled exoskeleton </h2><p>Sidhu, a junior at <a href="https://www.bethpagecommunity.com/o/bhs" rel="noopener noreferrer" target="_blank">Bethpage High School</a>, in New York, took second place for <a href="https://isef.net/project/robo024-mind-controlled-lower-limb-pneumatic-exoskeleton" rel="noopener noreferrer" target="_blank">NeuroGait</a>, a mind-controlled, lower-limb <a href="https://spectrum.ieee.org/soft-exoskeleton-motor-free" target="_self">exoskeleton</a>. He says he was inspired by his volunteer work at a community center that lacked elevators. He saw individuals with mobility issues struggle to navigate the three flights of stairs.</p><p>NeuroGait<em> </em>operates by reading the Bereitschaftspotential (BP), a faint electrical pattern that emerges one to two seconds before a person consciously initiates movement. Using a custom electroencephalogram (EEG) headset and a convolutional neural network (CNN), the system classifies intended movements and sends commands to a 3D-printed exoskeleton. Rather than rigid motors, the suit relies on pneumatic artificial muscles that Sidhu designed to mimic human anatomy.</p><p>“The pneumatic artificial muscle in itself is so compliant that it’s able to adjust to the limitations of the human body,” he says.</p><p>The technical specifications are striking: The CNN achieves a 99.9 percent accuracy in detecting a person’s intended movement, while the full system—from the brain’s signal to physical movement—operates at 95.2 percent accuracy, according to the results from 500 trials Sidhu conducted. </p><p>Perhaps most impressively, Sidhu built the entire system for about $276, less than 1 percent of the $40,000 to $100,000 price tag of commercial exoskeletons, according to a <a href="https://www.rootsanalysis.com/reports/medical-exoskeleton-market.html" rel="noopener noreferrer" target="_blank">2025 revenue report</a> from Roots Analysis.</p><p>He says he hopes to bring NeuroGait<em> </em>to the community center where the idea for the project began.</p><p>He attributes his success to staying current with research from institutions and organizations such as <a href="https://bostondynamics.com/" rel="noopener noreferrer" target="_blank">Boston Dynamics</a> and <a href="https://www.mit.edu/" rel="noopener noreferrer" target="_blank">MIT</a>.</p><p>“To be successful in research,” he says, “you have to know what’s being done right now.”</p><h2>A spider-inspired robot </h2><p>Hung, a sophomore at <a href="https://ecgauchos.wccusd.net/" rel="noopener noreferrer" target="_blank">El Cerrito High School</a>, in California, took third place for <a href="https://www.societyforscience.org/press-release/regeneron-isef-2026-special-awards-ceremony/" rel="noopener noreferrer" target="_blank">Math Into Motion: Robotic Hexapod for Hazardous Environments</a>. The six-legged robot is designed to traverse terrain too unstable for humans or conventional robotic systems.</p><p>With only weeks before the science fair deadline for entries and no prior electrical engineering experience, Hung began with an idea inspired by his interest in spaceflight: an insectlike robot. He had spent years watching rovers such as<em> </em><a href="https://science.nasa.gov/mission/msl-curiosity/" rel="noopener noreferrer" target="_blank"><em><em>Curiosity</em></em></a> and <a href="https://science.nasa.gov/mission/mars-2020-perseverance/" rel="noopener noreferrer" target="_blank"><em><em>Perseverance</em></em></a><em> </em>struggle on uneven surfaces, leading him to hypothesize that a hexapod design would be better for rugged ground.</p><p>As the project progressed, the humanitarian applications for his robot became clearer, he says. Watching news reports of the earthquake that struck Türkiye in 2023, as well as conflicts around the globe, Hung adapted his robot for use in disasters. The hexapod’s stable tripod walking gait, in which three legs stay grounded while the other three move, makes it well suited for navigating in collapsed buildings to locate survivors or to carry sensitive supplies such as insulin in conflict zones.</p><p>The current version moves using three mathematical techniques. Inverse kinematics converts a target leg position into the motor angles needed to reach it. Linear interpolation breaks each movement into a series of smaller steps for smoother motion. And Euclidean transformations translate the robot’s travel direction into instructions that each leg can follow, regardless of the way a leg happens to be facing.</p><p>Hung taught himself how to design a printed circuit board. He also taught himself 3D modeling, coding, and soldering. Figuring out the complicated mathematical transformations to coordinate legs facing different directions proved to be the toughest hurdle, he says.</p><p>After seven months of development and trial and error, a critical circuit board failure in his third version nearly ended the project, he says.</p><p>“There was a really strong moment of ‘Should I just give up?’” he recalls.</p><p>He simplified the design and rebuilt it from the ground up.</p><p>“I just decided to double down,” he says. The fourth version of the robot was the first that successfully walked across his living room floor.</p><p>He advises aspiring engineers that “if you find the right project and it truly becomes your passion, designing it almost starts to feel like fun, and that’s what carries you through.”</p><p>As the three young innovators demonstrate, the future of engineering goes far beyond technical ingenuity. Much is rooted in empathy and a commitment to human welfare.</p><p>Through initiatives such as the IEEE Presidents’ Scholarship, the IEEE Foundation showcases and nurtures bright minds poised to shape the next era of assistive technology and robotics.</p><p>For Tang, Sidhu, and Hung, the ISEF stage is just the beginning. They can look forward to impactful careers dedicated to advancing technology for the benefit of humanity.</p>]]></description><pubDate>Mon, 17 Aug 2026 18:00:04 +0000</pubDate><guid>https://spectrum.ieee.org/ieee-presidents-scholarship-2026</guid><category>Robots</category><category>Type-ti</category><category>Ieee-news</category><category>Students</category><category>Biomedical</category><category>Ieee-presidents-scholarship</category><dc:creator>Dov Fine</dc:creator><media:content medium="image" type="image/jpeg" url="https://spectrum.ieee.org/media-library/three-high-school-students-posing-with-their-individual-award-plaques-next-to-a-middle-aged-white-woman.jpg?id=67634200&amp;width=980"></media:content></item><item><title>From AI Copilots to Agent Swarms</title><link>https://spectrum.ieee.org/amd-agent-swarms</link><description><![CDATA[

Last year, I </span><a href="https://spectrum.ieee.org/beyond-code-autocomplete" target="_self">wrote</a><span> about <a href="https://www.amd.com/en.html" target="_blank">AMD’s</a> plans to use AI not just for </span><a href="https://spectrum.ieee.org/best-ai-coding-tools" target="_self">generating</a><span> new lines of code, but also for other steps in the software development lifecycle (SDLC), such as triaging problems, debugging code, and testing the software. At the time, we were hoping for a 25 percent productivity boost from AI use over the course of two or three years.</span></p><p>But with each new release, the capabilities of large language models (LLMs) improve dramatically—accelerating software development, increasing the quality of AI-generated code, and fundamentally reshaping how software is engineered. Now, just one year later, we have surpassed our productivity target, achieving a 30 percent overall productivity boost through AI. On top of that, we are rethinking not only how we use AI within the SDLC, but the structure of the SDLC itself.</p><p>We believe that the biggest AI revolution in software engineering is still ahead. So far, we have largely been teaching AI how we perform tasks and asking it to mimic existing workflows. In many ways, this constrains AI to human patterns of thinking. The next transformation will come from collaborative swarms of AI agents capable of discovering solutions independently.</p><h2>Agents of today</h2><p>AMD began developing AI systems for code generation, testing automation, bug analysis, and code review in 2024. At the time, our objective was to achieve 25 percent AI-generated production code by 2027 while gradually automating larger portions of the SDLC.</p><p>Measuring productivity is inherently <a href="https://metr.org/blog/2025-07-10-early-2025-ai-experienced-os-dev-study/" target="_blank">challenging</a>, but from the outset we have consistently tracked one objective metric: the percentage of source code generated by AI. Importantly, we count only code that passes all reviews and testing and is ultimately included in the final product. While AI-generated code is certainly not the only contributor to productivity gains, it is one of the few metrics that can be measured objectively and consistently.</p><p>By this metric, we have crossed the 20 percent mark at the beginning of this year and are now progressing towards 50 percent across entire codebase. In some software components, more than 80 percent of the code is now generated using AI.</p><p>Agentic AI has enabled us to include AI in every step of the life cycle: For <strong>code analysis and triage</strong>, agents are trained to analyze problem reports, identify and group similar requests, and highlight which code snippets are likely to need modification. For <strong>debugging and code generation</strong>, agents are directed to analyze a bug request and implement required code changes. For <strong>testing</strong>, the agents generate unit tests, and if those are passed, identify necessary integration and product-level tests. And finally, for the <strong>approval and release</strong> stage, agents prepare architecture summary, code change review, and full test results for engineers’ review and approval—and, if approved, integrate the changes into the next release.</p><h2>Agents of tomorrow</h2><p>Today, engineers create AI agents in their own image: They teach AI what they know about the system, how they would fix an issue, and how they would implement a change. This is already a major technological advancement. Engineers can create multiple “AI versions” of themselves, allowing these agents to work in parallel, scaling their expertise far beyond the limits of individual productivity. The limitation, however, is that these AI agents are still constrained by human thinking and human-defined approaches.</p><p class="shortcode-media shortcode-media-rebelmouse-image"> <img alt="Person typing on a keyboard. Looming in front of them is a network of colorful AI agents surrounding a glowing central node." class="rm-shortcode" data-rm-shortcode-id="0d892f7d0215c3159d9e41db8419441a" data-rm-shortcode-name="rebelmouse-image" id="73c7c" loading="lazy" src="https://spectrum.ieee.org/media-library/person-typing-on-a-keyboard-looming-in-front-of-them-is-a-network-of-colorful-ai-agents-surrounding-a-glowing-central-node.jpg?id=67609528&width=980"/> <small class="image-media media-photo-credit" placeholder="Add Photo Credit...">AMD</small></p><p>We believe the next major transformation in software engineering will occur when collaborative AI agent swarms can independently identify and develop solutions, guided by humans on what to solve rather than constrained by human assumptions about how the job should be done. Instead of providing detailed instructions on how to solve a problem, engineers will define the issue, the desired outcome, and the quality, performance, and system constraints, allowing AI agents to determine the optimal path to a solution.</p><p>A swarm of AI agents will then work in parallel to generate, evaluate, and refine multiple solution approaches. These agents will automatically validate correctness, measure performance, test trade-offs, and compare alternative implementations against defined success criteria. Finally, AI agents will prepare ranked solution options, along with validation results and performance metrics, for engineer review and approval. The agents won’t be enhancing each step of the SDLC—they will be rewriting the SDLC themselves.</p><p>To get to this point, we need to change how agents are trained. Today, improvement occurs one engineer and one agent at a time: An engineer reviews the output, refines the prompt, and repeats the process. To scale beyond this model, agents must continuously learn from one another, reuse successful strategies, and improve collaboratively across projects and teams.</p><p>We are already moving in this direction by using multi-agent workflows extensively through agentic harnesses, such as Codex and Claude Code, while simultaneously developing our own internal multi-agent systems to support the next generation of AI-driven software engineering.</p><p>A good example is our AI-driven effort to resolve issues in our Radeon Software eXperience (RSX). RSX is a user interface component that allows users to configure and monitor graphics driver behavior. In October 2025, we began using AI agents to automatically debug and fix reported RSX issues. Out-of-the-box AI tools delivered limited results, resolving only 6 percent of issues.</p> <p class="shortcode-media shortcode-media-rebelmouse-image"> <img alt="A bar chart labelled RSX-Agentic Resolution Rate shows large percentage increases from 6 in October 2025 to 75 in June 2026." class="rm-shortcode" data-rm-shortcode-id="98d6334ebf612596d6de9b5137c39de6" data-rm-shortcode-name="rebelmouse-image" id="d27a2" loading="lazy" src="https://spectrum.ieee.org/media-library/a-bar-chart-labelled-rsx-agentic-resolution-rate-shows-large-percentage-increases-from-6-in-october-2025-to-75-in-june-2026.jpg?id=67609523&width=980"/> <small class="image-media media-caption" placeholder="Add Photo Caption...">The percentage of software issues fixed automatically by AI agents in AMD’s Radeon Software eXperience (RSX) has been growing steadily, reaching 75 percent in June 2026. </small></p> <p class="media-body"><span>As we analyzed failures and identified ways to improve, we built a learning loop—initially a largely manual process—to understand where the agents were falling short and how to improve them. Rather than retraining the underlying models, we refined the objectives given to the agents, allowing them to iteratively explore multiple approaches, evaluate the results against defined success criteria, and converge on better solutions. At the same time, advances in models and agent run-times further increased effectiveness. Together, these improvements significantly increased our resolution rate from 6 percent to more than 75 percent of RSX issues resolved by agentic loop.</span></p><p>To make agents and agent swarms truly productive, we need a continuous learning loop that feeds errors and human interventions back into future agent workflows. The opportunity is to engineer this loop around clear, measurable goals. Each cycle captures new insights, making the entire AI engineering workflow smarter and more effective. Over time, this self-reinforcing loop—not just the underlying model—will become a key driver of AI progress.</p><h2>The evolving role of human engineers</h2><p>At AMD, we view AI as a means of increasing productivity, improving quality, and enabling employees to focus on higher-value work. Our goal is to empower our workforce with AI, not to reduce headcount.</p><p>To support this transformation, we are investing heavily in AI education and training across the company. The way we work is evolving rapidly, and we want every AMD employee to be prepared to leverage AI confidently, responsibly, and effectively.</p><p>As AI agents continue to improve, engineers will spend less time manually implementing solutions, focusing more on defining specifications, validating outcomes, and making the strategic decisions that drive innovation.</p>]]></description><pubDate>Mon, 17 Aug 2026 14:00:01 +0000</pubDate><guid>https://spectrum.ieee.org/amd-agent-swarms</guid><category>Agentic-ai</category><category>Software-engineering</category><category>Amd</category><category>Large-language-models</category><dc:creator>Andrej Zdravkovic</dc:creator><media:content medium="image" type="image/jpeg" url="https://spectrum.ieee.org/media-library/colorful-3d-blocks-piled-behind-glass-panels-displaying-white-code-snippets.jpg?id=67609515&amp;width=980"></media:content></item><item><title>Digital Signal Processing Pioneer Bede Liu Dies At 91</title><link>https://spectrum.ieee.org/digital-signal-processing-pioneer-bede-liu</link><description><![CDATA[

He was 91.</p><p>Liu was widely regarded as one of the founders of modern digital signal processing, a field that applies mathematical algorithms to analyze, modify, and transmit signals including sound, images, and video.</p><p>The IEEE Life Fellow taught electrical engineering at <a href="https://www.princeton.edu/" rel="noopener noreferrer" target="_blank">Princeton</a> for more than 50 years. From 1994 to 1997, he chaired the university’s <a href="https://ece.princeton.edu/front" rel="noopener noreferrer" target="_blank">electrical and computer engineering department</a>.</p><p>Liu’s research aided the transition from analog to digital processing of sound, images, and video. His work helped establish many of the mathematical and engineering techniques that underpin modern communications, multimedia systems, and consumer electronics.</p><p>Although little known outside engineering circles, his work is embedded in technologies used by billions of people. The low-power digital signal processors that make cellphone calls, streaming video, and Internet communications possible can be traced to research he conducted in the 1970s and ‘80s.</p><p>Liu received the 2018 <a href="https://corporate-awards.ieee.org/award/ieee-jack-kilby-signal-processing-medal/" rel="noopener noreferrer" target="_blank">IEEE Jack S. Kilby Signal Processing Medal</a> for “sustained contributions to the analysis and the development of low-complexity realizations of digital signal processing algorithms.”</p><p>“We stream music and video. We take photos with our phones, and we send them around. We don’t even think about it,” IEEE Life Fellow <a href="https://ece.princeton.edu/people/h-vincent-poor" rel="noopener noreferrer" target="_blank">H. Vincent Poor</a> said in an <a href="https://engineering.princeton.edu/news/2026/06/24/bede-liu-pioneer-digital-signal-processing-and-beloved-mentor-dies-age-91" rel="noopener noreferrer" target="_blank">obituary for Liu</a>. “But it’s all because of the signal processing, image processing, and video processing that’s been developed over the years, as well as other technologies that have grown up beside it and enabled it, like semiconductors. The development of these processing advances was exactly what Bede was a major part of.” Poor is a professor of electrical and computer engineering at Princeton.</p><h2>An impactful scholar and teacher</h2><p>Liu was born in Shanghai in 1934. During his childhood, his family relocated to Taiwan amid the upheaval of the <a href="https://en.wikipedia.org/wiki/Chinese_Civil_War" rel="noopener noreferrer" target="_blank">Chinese Civil War</a>. His father, Henry Liu Sr., was an electrical engineer.</p><p>Liu earned his bachelor’s degree in electrical engineering in 1954 from the <a href="https://www.ntu.edu.tw/english/" rel="noopener noreferrer" target="_blank">National Taiwan University</a>, in Taipei. After graduating, he and his family moved to the United States. Liu and his father attended the Polytechnic Institute of Brooklyn (now the <a href="https://engineering.nyu.edu/" rel="noopener noreferrer" target="_blank">New York University Tandon School of Engineering</a>) together. They earned their master’s degrees in electrical engineering in 1956. Liu continued his studies at the school, earning a doctoral degree in electrical engineering four years later.</p><p>In 1959 he was awarded a <a href="https://spectrum.ieee.org/7-bell-labs-ieee-milestones" target="_self">Bell Labs</a> <a href="https://www.nokia.com/bell-labs/institute/media/bell-labs-fellows/" rel="noopener noreferrer" target="_blank">fellowship</a> and worked at the company’s Murray Hill, N.J., location until he joined Princeton in 1962.</p><p>“Liu was a highly impactful scholar and teacher—always thinking ahead of future needs and changing technologies,” said IEEE Life Fellow <a href="https://ece.princeton.edu/people/peter-j-ramadge" rel="noopener noreferrer" target="_blank">Peter J. Ramadge</a>, a Princeton professor emeritus of engineering.</p><p>Cellphones make use of a considerable amount of digital signal processing, Liu once noted. Many of the field’s advances, he added, involved making sophisticated processing practical on devices with limited computing power—which is the challenge that confronted generations of engineers designing portable electronics.</p><p>Liu’s research contributions helped shape both the theory and practice of digital signal processing. With <a href="https://en.wikipedia.org/wiki/Abe_Peled" rel="noopener noreferrer" target="_blank">Abe Peled</a>, a former graduate student, he authored the 1976 textbook <a href="https://www.amazon.com/Digital-Signal-Processing-Theory-Implementation/dp/0471019410" rel="noopener noreferrer" target="_blank"><em><em>Digital Signal Processing: Theory, Design, and Implementation</em></em></a>, which is a standard reference for engineers. Published before digital signal processing had fully emerged as a distinct discipline, it helped define the subject for practitioners and students around the world.</p><p>Liu also published 250 technical papers and was granted 12 U.S. patents. His papers are available to read on the <a href="https://ieeexplore.ieee.org/author/37087189074" rel="noopener noreferrer" target="_blank">IEEE Xplore Digital Library</a>.</p><p>The first patent granted to him and Peled was in 1976 for a hardware design that processed bits in parallel, rather than in sequence. The innovation greatly increased computing efficiency for data including sound and communication signals.</p><p>Peled says Liu “demonstrated an openness to new ideas and a willingness to challenge the orthodoxy of the EE department at that time—which leaned heavily toward more theoretical information theory.”</p><h2>A mentor to well-known engineers</h2><p>Liu’s influence extended beyond his own research. He advised 53 doctoral students, many of whom went on to distinguished careers in academia and industry, including leadership positions at <a href="https://about.google/" rel="noopener noreferrer" target="_blank">Google</a> and <a href="https://www.ibm.com/about" rel="noopener noreferrer" target="_blank">IBM</a>. One former student, computer scientist <a href="https://spectrum.ieee.org/bob-kahn-2667754905" target="_self">Robert Kahn</a>, helped create the architecture of the modern Internet. Kahn, an IEEE Life Fellow, received the 2024 <a href="https://spectrum.ieee.org/medal-of-honor-bob-kahn" target="_self">IEEE Medal of Honor</a>.</p><p>“His former students were very successful,” Poor said of Liu, “and I think that’s a testament to his skill as a mentor.”</p><p class="pull-quote">“Liu was a highly impactful scholar and teacher—always thinking ahead of future needs and changing technologies.”<strong>—Peter J. Ramadge</strong></p><p>Together with several Ph.D. students, Liu developed methods of filtering and compressing digital signals to mitigate errors and dramatically reduce the computation needed for signal processing.</p><p>As digital signal processing moved from laboratories into commercial products, the impact of Liu’s ideas spread across industries. His research helped spawn the development of lower-cost and lower-power electronics and contributed to advances in mobile communications, multimedia technology, industrial automation, and biomedical imaging.</p><h2>A focus on media integrity and copyrights</h2><p>In the 2000s, Liu turned his attention to media integrity and copyright issues.</p><p>“With the increasing accessibility of digital media source material, the protection of ownership and the prevention of unauthorized alteration has become an important concern,” he wrote in his 2002 book, <a href="https://www.amazon.com/Multimedia-Data-Hiding-Min-Wu/dp/0387954260" target="_blank"><em><em>Multimedia Data Hiding</em></em></a>. The book, which he co-wrote with his former doctoral student IEEE Fellow Min Wu, discussed the theory, techniques, applications, and security of digital watermarking—hidden signals that could identify a genuine copy of a song, image or video to prevent unauthorized distribution or tampering.</p><p>A Princeton team that included Liu, Wu, and another of his doctoral students uncovered serious vulnerabilities in watermarking technologies being considered by an industry consortium. They found that the standardization efforts were immature and would not protect against digital piracy.</p><p>“Now nearly every copy of a Hollywood film given to a critic or theater carries a unique digital forensic watermark to prevent unauthorized redistribution,” said Wu.</p><h2>A force in the community</h2><p>Liu, an active IEEE volunteer, served on the <a href="https://www.ieee.org/about/corporate/board" rel="noopener noreferrer" target="_blank">IEEE Board of Directors</a> in 1984 and 1985. He was the 1982 president of the <a href="https://ieee-cas.org/welcome" rel="noopener noreferrer" target="_blank">IEEE Circuits and Systems Society</a>.</p><p>He was a member of the U.S. <a href="https://www.nae.edu/" rel="noopener noreferrer" target="_blank">National Academy of Engineering</a>, an academician of China’s <a href="https://www.nature.com/articles/136208a0" rel="noopener noreferrer" target="_blank">Academia Sinica</a>, and a foreign member of the <a href="https://english.cas.cn/" rel="noopener noreferrer" target="_blank">Chinese Academy of Sciences</a>.</p><p>Outside the classroom, he was recognized for his humility, humor, enthusiasm, and generosity. When thinking of Liu, IEEE Life Fellow <a href="https://www.cs.princeton.edu/~ken/" rel="noopener noreferrer" target="_blank">Kenneth Steiglitz</a> says, <em><em>cheer</em></em> is the first word that comes to mind.</p><p>Liu was “always ready with a positive remark, a quick smile or, maybe, some tips on the right way to cook a duck,” says Steiglitz, professor emeritus of computer science at Princeton.</p><p>Liu encouraged his students to take on ambitious, unconventional projects, and he inspired students and colleagues with his adventurous spirit.</p>]]></description><pubDate>Fri, 14 Aug 2026 18:00:02 +0000</pubDate><guid>https://spectrum.ieee.org/digital-signal-processing-pioneer-bede-liu</guid><category>Ieee-member-news</category><category>In-memoriam</category><category>Obituary</category><category>Digital-signal-processing</category><category>Ieee-awards</category><category>Type-ti</category><dc:creator>The Liu Family</dc:creator><media:content medium="image" type="image/jpeg" url="https://spectrum.ieee.org/media-library/portrait-of-an-elderly-asian-man-softly-smiling-in-a-suit-jacket-and-tie.jpg?id=67609508&amp;width=980"></media:content></item><item><title>Predict Antenna Coupling on Electrically Large Platforms Before Building Hardware</title><link>https://content.knowledgehub.wiley.com/efficient-and-accurate-prediction-of-cosite-isolation-on-large-platforms/</link><description><![CDATA[

<img src="https://spectrum.ieee.org/media-library/an-illustration-of-stylized-people-wearing-business-casual-clothing.webp?id=65257424&width=1245&height=700&coordinates=0%2C112%2C0%2C113"/><br/><br/><p>If you haven’t already seen a job listing for a “product engineer,” you probably will soon. The job everyone’s suddenly hiring for, this role is like a cross between a product manager and an engineer (as the name suggests). And it’s a hiring trend worth paying attention to.</p><p>Companies are opening more of these roles every single month, but they’re struggling to fill them. The reason has almost nothing to do with engineers’ coding skills or years of experience.</p><p>The best career move you can make to prepare for these types of roles has almost nothing to do with getting more technical. Instead, it comes down to one of the fluffiest, most overused, and potentially cringiest words in all of tech: <strong>mindset</strong>.</p><p>Stick with me, I promise this goes somewhere useful.</p><h2>The problem: We were trained to be task-takers</h2><p>When I started out, my job looked like this:</p><p>Drive to an office. Sit through meetings that led to other meetings until a project manager handed me a task they’d already chopped into tiny pieces.</p><p>My job was to turn that task into code.</p><p>It took years for me to get good at a coding language and tech stack, and once I did, I executed that knowledge against specs that somebody else wrote.</p><p>You know what’s freakishly good at that exact job? I’ll give you a hint: It starts with A and ends with I.</p><p>Boris Cherny, the creator of Claude Code, recently said: “coding is basically solved,” and <strong>“the bottleneck is going to be good ideas.” </strong></p><p>So if your entire value is “hand me a task and I’ll build it,” you’re in a footrace with the robots. I don’t like that for you.</p><h2>The bad news... that is also good news</h2><p>Many companies are flattening. Middle management is getting stripped out, for better or worse (mostly for worse), which means many of us are doing more with less.</p><p>This might sound like purely more work, but it’s also an opening for anyone who cares about what they’re building and can put on their manager hat. Companies are no longer just hunting for the strongest engineer in one narrow domain.</p><p>What’s rare, and what actually moves revenue, is an engineer who can spot the thing that’s quietly costing money and either flag it to leadership or just go fix it.</p><h2>What this actually looks like</h2><p>Being product-minded has NOTHING to do with your tech stack.</p><p>Here’s where to start:</p><p><strong>Have an opinion and back it up.</strong> As a former engineering manager, the worst thing I ever heard was silence. I’d often ask the team what they thought because I doubted myself and wanted a gut check. I was grateful to the ones who said “nope, bad idea, here’s why.” <strong>Pushback is a gift.</strong></p><p><strong>Learn the domain, casually.</strong> Work for a plumbing company? You don’t need to become a plumber, but spend an hour on Reddit threads where plumbers vent. Now your ideas come from your potential customers.</p><p><strong>Make experiments cheap and safe.</strong> This is where any engineer has massive leverage. Experiments are not free. A bad one loses customers and frustrates users. Tools like LaunchDarkly and Optimizely let you ship a change to 5 percent of users and roll it back the second it tanks. Learn them, or build a scrappy version yourself. A team that can quickly run safe experiments will out-learn everyone else in the building.</p><p><strong>Be data-driven.</strong> Stop fighting about button colors. Pick a goal: making money, finding product-market fit, or making the product sticky so people come back. Then measure it. If your gorgeous redesign tanks time-on-site, it failed, no matter how good it looked to you. If the ugly version makes more money, ship the ugly version.</p><p><strong>You don’t have to be the ideas person.</strong> Maybe you’re not a visionary. That’s fine. Organize a hackathon around an actual company goal. Pull up your company’s quarterly targets and build something against one of them. Don’t know what those targets are? That’s your first assignment.</p><h2>Good ideas are the new bottleneck—and they always have been</h2><p>When I was a manager, I asked myself one question every week: <strong>What’s the single most impactful thing I could do right now?</strong> The answer was almost never “write more code.” It was understanding a gnarly problem nobody had defined yet. Building a deck to spread knowledge that was in one person’s head. Getting the right three people in a room to actually make a decision we’d been putting off.</p><p>Code is cheap, and it always has been. We just couldn’t see it, because for decades the typing took so long that it felt like the hard part. It never was. The hard part was always knowing what’s worth building.</p><p>— Brian</p><h2><a href="https://spectrum.ieee.org/siobahn-day-grady-ai-hbcu" target="_self">Siobahn Day Grady Wants Everyone to Be AI Literate</a></h2><p>In January 2025, Siobahn Day Grady launched the first AI research institute at a historically Black college or university.

The company’s tagline: “We break rocks with electricity.”</p><p>Eden’s researchers hope their rock-breaking technique will someday aid mineral mining, tap geothermal heat, or create geologic storage areas for carbon. But there’s an even more intriguing use that could create a whole new category of energy production: generating hydrogen underground.</p><p>The dream of a hydrogen-powered economy dates back to the 1970s, when petroleum shortages and rising concerns about pollution from fossil fuels sparked visions of cars, ships, planes, and industrial machines running on hydrogen instead of carbon. Hydrogen is often touted as a clean fuel because when it’s burned or consumed in fuel cells, it emits only water and heat. However, it currently takes more energy to make than it yields, and the cheapest and most common way is by reacting steam with methane, a potent greenhouse gas.</p><h3>How to Break Rocks With Electricity</h3><br/><img alt="Cross section of two deep, underground wells, each with an electrode in them and electricity flowing between in a complex network." class="rm-shortcode" data-rm-shortcode-id="68ad4714a1e2f11ce3f0c78e3c4ac83e" data-rm-shortcode-name="rebelmouse-image" id="a2298" loading="lazy" src="https://spectrum.ieee.org/media-library/cross-section-of-two-deep-underground-wells-each-with-an-electrode-in-them-and-electricity-flowing-between-in-a-complex-networ.png?id=67600101&width=980"/><p>It’s possible to make zero-carbon hydrogen by splitting water with <a href="https://spectrum.ieee.org/anion-exchange-membrane-electrolyzer" target="_blank">electrolyzers powered by renewable energy</a>. But in most cases, the process is too expensive to be economical—a reality that burst the hydrogen-hype bubble in the early 2020s. Global demand for hydrogen in 2024 reached approximately 100 million tonnes, containing energy equal to only about 3 percent of the world’s annual energy consumption. Most of it is used as chemical feedstock for petroleum refining and for making fertilizers and plastics.</p><p>The frustrations of manufacturing clean hydrogen have convinced many entrepreneurs and scientists to instead seek the element underground. For the past half-decade, dozens of companies around the world have been hunting for buried stores of hydrogen, called natural or geologic hydrogen. But with a commercial-scale operation yet to be proved, Eden and a handful of other startups and research groups are chasing the more audacious scheme of producing geologic hydrogen artificially.</p><p>This approach, known as stimulated geologic hydrogen or engineered hydrogen, turns subterranean rock formations into giant hydrogen factories. It typically involves injecting water into iron-rich rock, which oxidizes the iron and releases hydrogen as a by-product. Fracturing the rock, as Eden is doing, creates a network of conduits for the water to reach iron-bearing minerals.</p><p>The concept of stimulated hydrogen is so new that few have had a chance to test it. Proponents say that if it works—which is a big “if”—it could provide almost unlimited energy for the indefinite future. There’s one way to find out: Start breaking rocks.</p><h2>There’s Plenty of Underground Hydrogen</h2><p>Hydrogen is the simplest and most abundant element in the universe, the stuff of stars and galaxies. Geologists have long known that Earth generates hydrogen gas through natural water-rock reactions, but until recently, the occurrence was regarded as a curiosity. The gas is so light that most experts assumed it all escaped through pores and cracks in Earth’s subsurface and didn’t accumulate in useful quantities.</p><p class="shortcode-media shortcode-media-rebelmouse-image"> <img alt="A man\u2019s hands hold a metal cylinder with two capped wires sticking out." class="rm-shortcode" data-rm-shortcode-id="b097f20cc812fa5699a44762beb991b6" data-rm-shortcode-name="rebelmouse-image" id="103ce" loading="lazy" src="https://spectrum.ieee.org/media-library/a-man-u2019s-hands-hold-a-metal-cylinder-with-two-capped-wires-sticking-out.jpg?id=67599074&width=980"/> <small class="image-media media-caption" placeholder="Add Photo Caption...">During a demonstration at Eden’s testing site near Boston, an employee displays a central component of the company’s proprietary electrode. </small><small class="image-media media-photo-credit" placeholder="Add Photo Credit...">Bob O’Connor</small></p><p>Inklings that they were wrong emerged in the 19th and 20th centuries, when researchers in the former Russian Empire and Soviet Union reported hydrogen seeping from mines and wells. But in the ongoing frenzy for fossil fuels, these observations were largely overlooked or forgotten. Scientists later discovered hydrogen spewing from hydrothermal vents in the seafloor and feeding so-called eternal flames, like those of Türkiye’s Mount Chimaera, where ancient athletes lit torches for the first Olympic games.</p><p>Then, in 1987, in the village of Bourakébougou, Mali, people drilling a water well noticed a breeze blowing out of the hole. According to local lore, a worker leaned in for a closer look, a lit cigarette dangling from his mouth. The air instantly ignited, burning a brilliant blue.</p><p>The crew capped the well, which stayed sealed for 25 years until, in 2012, a Malian oil and gas prospector confirmed the ground contained a large reservoir of hydrogen. The prospecting company, now called <a href="https://hydroma.ca/" target="_blank">Hydroma</a>, had a small electrical plant constructed to convert the gas into power for the village’s residents. Soon after, startups in Australia, Canada, the United States, and elsewhere began searching for more hydrogen stores. By 2025, large multinational petroleum and mining companies were getting in on the game.</p><p>To date, hundreds of exploratory wells have been drilled across the globe. But although researchers have documented widespread hydrogen deposits, none have proved capable of producing the gas at rates and quantities needed for commercialization. “We’ve poked a lot of holes, and nobody has found the gusher—or at least they’re not talking about it,” says <a href="https://www.linkedin.com/in/douglas-wicks-10b213/" target="_blank">Douglas Wicks</a>, a former program director at the United States’ <a href="https://arpa-e.energy.gov/" target="_blank">Advanced Research Projects Agency—Energy</a> who now advises companies pursuing geologic hydrogen.</p><p class="shortcode-media shortcode-media-rebelmouse-image rm-float-left rm-resized-container rm-resized-container-25" data-rm-resized-container="25%" style="float: left;"> <img alt="A pipe about the size of a fist sticking out of the ground by a few inches, with cables protruding from it." class="rm-shortcode" data-rm-shortcode-id="64f36e3c96cb5e9060ad03e44242eeb0" data-rm-shortcode-name="rebelmouse-image" id="1fe3d" loading="lazy" src="https://spectrum.ieee.org/media-library/a-pipe-about-the-size-of-a-fist-sticking-out-of-the-ground-by-a-few-inches-with-cables-protruding-from-it.jpg?id=67599081&width=980"/> <small class="image-media media-caption" placeholder="Add Photo Caption...">A wellhead guides multiple lines downhole: fluid hose, electric cables, rope, control for a sealing device, and sensor communication.  </small><small class="image-media media-photo-credit" placeholder="Add Photo Credit...">Bob O’Connor</small></p><p>Wicks says that in 2022, while at ARPA-E, he got “dragged into the rabbit hole of geologic hydrogen” by <a href="https://www.linkedin.com/in/emily-yedinak-phd-958a2647/" target="_blank">Emily Yedinak</a>, then a Fellow at the agency, who was trying to convince her colleagues to take it seriously. “I was the ultimate doubter,” Wicks says. The astronomical price of electrolyzers had made him skeptical that clean hydrogen was a viable pursuit. Plus, if Earth really did contain vast pools of hydrogen, then surely humanity, which had been digging for natural resources for thousands of years, would have found them by now, he reasoned.</p><p>But after talking with geologists—who pointed out that people historically hadn’t found hydrogen because they hadn’t been looking for it—Wicks changed his tune. “I got the epiphany that geologic hydrogen is not just an accumulation; it’s a chemical reaction,” he says. “And if it’s a chemical reaction, then it can be stimulated.”</p><p>Finding large accumulations of geologic hydrogen entails stumbling on a Goldilocks set of conditions. You need iron-rich source rocks that have already produced or are producing bountiful hydrogen. You also need porous reservoir rocks that can hold sizable quantities of gas migrating from the source rocks. And you need solid cap rocks above the reservoir that trap the gas underground.</p><p>To stimulate hydrogen, however, you don’t need this just-right geology. All you need are iron-rich rocks, and then you can generate the hydrogen yourself.</p><p>“These rocks are everywhere,” Wicks says. “If you look at the amount of iron that’s within drilling range of Earth’s crust, you’re talking about quadrillions of tons of hydrogen being accessible. If we’re 1 percent successful just in the United States, we could power the economy for thousands of years.” A back-of-the-envelope calculation convinced him that the cost of stimulated geologic hydrogen could easily compete with hydrogen made from methane. “If we get the technology right,” he concludes, “this could be huge.”</p><p>Wicks wasn’t the first person to propose the idea, but he was the first to allocate major funding. In 2024, under his leadership, ARPA-E awarded US $20 million to 16 teams aiming to advance stimulation technologies and research. Winning ideas included fracturing rocks with fluid pressure or mechanical stimuli, exposing them to catalysts to speed hydrogen-generating reactions, and manipulating native microbial communities to enhance production. Eden’s rock-breaking project, the lone electricity-based approach, received $900,000.</p><h2>Eden GeoPower’s Underground Rock Fracturing</h2><p><a href="https://www.linkedin.com/in/paris-smalls/" target="_blank">Paris Smalls</a>, Eden’s CEO, founded the company in 2017 as a 23-year-old graduate student at MIT. For his Ph.D. in civil and environmental engineering, he was studying the effects of electricity on rock strength and became interested in enhanced geothermal systems, which require fracturing hot, dry rocks to circulate water through them for extracting heat. This is typically done by hydraulic fracturing, or fracking—a technique borrowed from the oil-and-gas industry that involves injecting high-pressure fluids.</p><p>Fracking is controversial because it can cause earthquakes and groundwater contamination, and many regions have banned the practice. From an engineering perspective, it’s also imprecise. The fractures it forms are large and difficult to control. “You can’t get enough fractures where you want because the water ends up just going through the same cracks,” Smalls explains. Electricity, he knew from his Ph.D. work, could create more extensive and finely tuned fracture networks, enabling geothermal systems to produce more heat with less environmental risk.</p><p class="shortcode-media shortcode-media-rebelmouse-image"> <img alt="A set of pipes and hoses connected together on a makeshift box.

But he hadn’t considered using it to make hydrogen. So when Wicks invited him to apply for the hydrogen program at ARPA-E, he was confused. “I didn’t get it at all,” Smalls says. “I’m like, ‘I break rocks. How am I going to generate hydrogen?’”</p><p>Not long after, Smalls met <a href="https://www.colorado.edu/earthscience/alexis-templeton" target="_blank">Alexis Templeton</a>, a geomicrobiologist at the University of Colorado Boulder who had become an expert in geologic hydrogen by studying microbes that consume the gas and the mineralogical transformations that create it. “There was a lot of early interest in whether or not you could engineer the production of hydrogen from rocks,” Templeton recalls. “And the rocks with some of the best potential have all the right chemistry, but they need water. Nobody was excited to do hydraulic fracturing. So everyone was wondering, ‘Well, how are we going to get the water in?’”</p><p>Eden’s technology, Templeton understood, could be the answer. She agreed to join the company part-time as its lead geochemist, a position she held from 2023 to 2025. During that time, Eden ran its first pilot experiment, in an oil field in Oman, near where Templeton was already doing her own hydrogen research. The initial setup used DC power to send a steady flow of tens of kilowatts between electrodes in two wells. When Smalls’s team tested it in a petroleum reservoir made of soft, chalky carbonate, the rock fractured readily, increasing oil production by 30 percent.</p><p>But when they did the same test in hard rocks, like those needed for hydrogen and geothermal systems, they didn’t fracture much at all. So the team went back to the drawing board and came up with a fix: pulsed power.</p><h2>Using Pulsed Power for Rock Fracturing</h2><p>The idea of breaking things using pulsed power—short, concentrated bursts of electrical energy—originated with a mid-20th-century experiment in Soviet-era Russia. As the story goes, a physicist and inventor named Lev Yutkin was out in a thunderstorm when he saw lightning strike a log underwater. Rather than burn, as it would in air, the log exploded, as if blown up by dynamite. Intrigued, Yutkin tried to reproduce the spectacle in his lab. He placed a dinner plate in a water tank, dipped in two wire electrodes, and released a high-voltage pulse. The ensuing spark, he discovered, instantly ionized the water molecules between the electrodes into a plasma channel, which then rapidly expanded, creating a shock wave that shattered the plate.</p><p>Yutkin described the phenomenon in his 1955 book <em><em>Electrohydraulic Effect</em></em>. He later proposed numerous fanciful uses for it, such as cleaning pipes or breaking up kidney stones, which inspired real tools in use today, including electrohydraulic drills and rock-crushers, and a kidney-stone-busting medical device called a lithotripter. The following decades saw advances in pulsed-power systems and experimental techniques to better understand the complex physical processes involved. By the 2020s, when Smalls’s team began investigating it for subterranean rock fracturing, the technology seemed ripe for use, although that particular application had been little explored outside the laboratory.</p><p class="shortcode-media shortcode-media-rebelmouse-image"> <img alt="Man sitting on a stool in a lab coat.

Instead of submerging each sample in water, however, they placed a pair of electrodes at opposite ends of the cylinder and delivered pulses directly to the rock. Using this dry-pulse method, drawn from Smalls’s and others’ research, the team found they could form plasma in tiny, moist pockets between mineral grains. “We essentially generate a plasma channel in the rock itself,” explains <a href="https://www.linkedin.com/in/rvillamor/" target="_blank">Rafael Villamor-Lora</a>, Eden’s vice president of research and development. With enough pulses, the fast-swelling channel, as in Yutkin’s investigation, induces a shock wave that fractures the rock.</p><p>To bring the technology to the field, Eden needed voltage high enough to break through meters of solid rock. The obvious solution was a Marx generator, which converts low-voltage DC power into high-voltage bursts by slowly charging and then rapidly discharging multiple capacitors in parallel. (Marx generators are commonly used in high-energy physics experiments and to simulate lightning strikes on power lines.) Eden custom-built two devices—named Zeus and Thor after the gods of thunder—which together can release a surge of several hundred kilovolts.</p><p>This time, the plan worked. In 2025, in an abandoned gold-and-silver mine in Colorado, Eden used Thor to successfully fracture a hard, igneous column, increasing its permeability tenfold.</p><p class="shortcode-media shortcode-media-rebelmouse-image"> <img alt="Man in a hard hat and overalls works on a chest-high metal box that reads \u201cDanger High Voltage.\u201d" class="rm-shortcode" data-rm-shortcode-id="dbe66496644de4788f791cc787c1d1ed" data-rm-shortcode-name="rebelmouse-image" id="904b5" loading="lazy" src="https://spectrum.ieee.org/media-library/man-in-a-hard-hat-and-overalls-works-on-a-chest-high-metal-box-that-reads-u201cdanger-high-voltage-u201d.jpg?id=67599118&width=980"/> <small class="image-media media-caption" placeholder="Add Photo Caption...">Ezra Frank, a mechanical engineer at Eden, works on Zeus, Eden’s custom Marx generator.  </small><small class="image-media media-photo-credit" placeholder="Add Photo Credit...">Bob O’Connor</small></p><p>In March this year, the company began setting up the test site on the Massachusetts horse farm to refine its systems and gather more data on how the technology performs in different geologic environments. Its engineers are also designing more powerful generators to discharge stronger and faster pulses. Because Zeus and Thor consume very little power—akin to running a toaster or two—it takes about a minute to store enough energy to fire a maximal pulse. It then takes around 100 pulses to penetrate around 10 meters of hard rock. So fracturing over longer distances or at multiple depths can take hours to days. That means Eden’s biggest cost is labor, not energy.</p><p>Smalls says Eden signed an agreement with a geologic hydrogen startup—he declined to say which one—to demonstrate electrical fracturing in a field pilot of stimulated hydrogen, which could begin late next year. Eden will need to prove its technology can help coax the gas from the ground at a profitable rate and cost.</p><p>“It’s no question whether we can produce hydrogen,” Villamor-Lora says. “The question is whether we can produce it fast enough to be economical.” In the lab, Eden researchers found they could generate up to four times more hydrogen from rock samples using the pulsed-power technique, compared with the amount found in unfractured samples. But that may not be enough to make stimulated hydrogen commercially viable without some additional technology.</p><h2>Other Approaches to Stimulated Geologic Hydrogen</h2><p>One of the biggest challenges in stimulating hydrogen is that there’s no obvious go-to recipe. Beyond the basic ingredients of water and iron, many factors affect how much hydrogen is generated and for how long, and fractures are only one factor. Laboratory studies have shown, for example, that the ideal temperature for maximizing hydrogen production is around 200 to 300 °C. Acidity, rock and water chemistry, and microbial inhabitants are other important considerations.</p><p>Making the puzzle more complex, each rock formation is different and may require different stimulation techniques or a combination of them. “There isn’t a single solution that will work everywhere,” says <a href="https://www.linkedin.com/in/alexei-tcherniak-1780b83a/" target="_blank">Alexei Tcherniak</a>, CEO of the hydrogen startup <a href="https://geokiln.com/" target="_blank">GeoKiln</a>. “You have to know the geology you’re operating in.”</p><p>Some promising rock formations, he points out, may already be fractured or porous enough to become saturated with water but too cool to make ample hydrogen naturally. To solve this problem, his company, based in Houston, uses a system of underground heaters originally developed for improving flow in heavy oil reservoirs and converting solid organic matter in young shale rock into extractable oil and gas. The heaters, which are commercially available, can be installed in boreholes drilled into hydrogen source rocks, similar to Eden’s electrodes. Tcherniak says that GeoKiln is ready to start field testing as soon as it can raise the capital.</p><p>Other researchers are exploring the use of catalysts—metal or chemical salts that speed hydrogen-generating reactions—which, they say, could replace or complement fracturing or heating to increase hydrogen production at less cost. <a href="https://www.vema.earth/" target="_blank">Vema Hydrogen</a>, for instance, is betting on a mixture of boiler-heated water and proprietary catalysts. “What I can say about our catalysts is basically what they are not, which is not toxic, not expensive, and not dangerous,” says <a href="https://www.linkedin.com/in/florian-osselin-80714a75/" target="_blank">Florian Osselin</a>, Vema’s chief science officer. The company, also headquartered in Houston, has begun drilling pilot wells in Canada to test its mysterious brew. By injecting it into semi-permeable rock, Vema expects to achieve commercial production rates without fracturing. “We’ve done field-scale numerical simulations that give us a lot of confidence,” Osselin says.</p><p>Another stimulation method, proposed by the Denver-based startup <a href="https://www.koloma.com/" target="_blank">Koloma</a>, aims to expose more rock surface for generating hydrogen by mimicking natural weathering. The technique involves adding carbon dioxide to water and injecting the fluid at specific times to control for factors like acidity and gas concentrations. The carbon dioxide reacts with the water to form an acid that breaks down mineral chains in rock pores, thereby increasing the pores’ surface area, explains <a href="https://www.linkedin.com/in/tom-darrah-785b5613/" target="_blank">Tom Darrah</a>, the company’s CTO, who studied and patented the method as a professor at Ohio State University. “I call it micro-pitting because the texture goes from smooth to rough,” he says. As with fracturing, more surface area means more hydrogen production—if you can get the formula right.</p><p><a href="https://engineering.tamu.edu/petroleum/profiles/okoroafor-rita-esuru.html" target="_blank">Rita Esuru Okoroafor</a>, an energy resources engineer at Texas A&M University, is studying the effects of various stimulation approaches, including fracturing, catalysts, and carbon-dioxide injection, on hydrogen generation. Her data, based on laboratory tests of rock samples from around the world and numerical models of stimulated geologic hydrogen systems, suggest that none of these approaches alone will sustain hydrogen production at rates needed for long-term commercial development. “We’re still fine-tuning our models, but they’re telling us that we’re going to need a lot of fracturing, we’re going to need catalysts, and then we’re going to need restimulation,” she says.</p><p>The process of generating hydrogen, Okoroafor explains, will eventually consume all the readily available iron in exposed rock surfaces, causing production to plummet. By accelerating hydrogen generation, catalysts also accelerate its decline. “When these reactions happen very fast, they also die very fast,” she says. They also leave behind mineral precipitates that can clog existing cracks. In a recent study, she found that hydrochloric acid helps clear the debris, expose fresh rock surfaces, and reopen water pathways to restore production.</p><p>It’s too early to know which technologies will win out in the race for geologic hydrogen and if stimulation will even be needed to make it a viable industry. What’s more, production is just the first step toward commercialization. Many questions remain. Once hydrogen is flowing from the ground, how will the gas be purified? How will it be stored and transported? How will the industry be regulated? What are the environmental risks, and how will they be mitigated? What will be the cost?</p><p>“With all these wars and gas prices going up, we need to be preparing for the future,” Smalls says. But as is often the case with nascent technology development, life gets in the way. At the horse farm, fracturing started in June after being delayed for months, first by a snowstorm and then minor equipment failures and other logistical snags. “Everything takes longer than you think,” Smalls says. Still, he’s unfazed, ever the optimist. “I like to go after things that other people are afraid to.” <span class="ieee-end-mark"></span></p>]]></description><pubDate>Tue, 11 Aug 2026 13:00:01 +0000</pubDate><guid>https://spectrum.ieee.org/stimulated-geologic-hydrogen</guid><category>Hydrogen</category><category>Green-hydrogen</category><category>Electrical-stimulation</category><category>Fracking</category><category>Hydraulic-fracturing</category><category>Hydrogen-production</category><dc:creator>Ariel Bleicher</dc:creator><media:content medium="image" type="image/jpeg" url="https://spectrum.ieee.org/media-library/on-the-left-a-man-in-a-collared-shirt-stands-smiling-with-hands-in-his-pockets-and-lab-equipment-in-the-background-on-the-ri.jpg?id=67598580&amp;width=980"></media:content></item><item><title>Navigating the Pivot From Tech Expert to Organizational Leader</title><link>https://spectrum.ieee.org/navigating-pivot-tech-expert-leader</link><description><![CDATA[

Not yet. </p><p>It was just 10 years ago that the Third-Generation Partnership Project (<a href="https://www.3gpp.org/" rel="noopener noreferrer" target="_blank">3GPP</a>) released its <a href="https://www.3gpp.org/news-events/3gpp-news/v2x-r14" rel="noopener noreferrer" target="_blank">initial cellular V2X standard</a>. The 3GPP have <a href="https://www.qualcomm.com/news/onq/2020/07/propelling-5g-forward-closer-look-3gpp-release-16" rel="noopener noreferrer" target="_blank">refined V2X</a> over three <a href="https://radcom.com/release-17-whats-new" rel="noopener noreferrer" target="_blank">major releases</a> since. In the U.S. and the EU, the FCC and related European agencies have put forward <a href="https://www.ettifos.com/post/dsrc-vs-cv2x" rel="noopener noreferrer" target="_blank">other standards</a> for short-range <a href="https://www.etsi.org/deliver/etsi_en/303700_303799/303797/02.01.01_60/en_303797v020101p.pdf" rel="noopener noreferrer" target="_blank">wireless V2X communication protocols</a>.</p><p>However, no consensus standard has yet emerged. So, lacking any clear, unambiguous guidance on the future of V2X networks, autonomous-car makers—like <a href="https://spectrum.ieee.org/full-autonomy-waymo-driver" target="_self">Waymo</a>, <a href="https://spectrum.ieee.org/robotics-experts-tesla-bot-optimus/experts-on-optimus" target="_self">Tesla</a>, <a href="https://spectrum.ieee.org/meet-zoox-the-robotaxi-startup-taking-on-google-and-uber" target="_self">Zoox</a>, and <a href="https://spectrum.ieee.org/gm-says-look-ma-no-steering-wheel" target="_self">Cruise</a>—have leaned more on self-reliance, bulking up each vehicle with as many sensors and GPUs as possible.</p><p>Here, though, is where O-RAN might be able to help. </p><p>A little like APIs (a.k.a. <a href="https://www.ibm.com/think/topics/api" rel="noopener noreferrer" target="_blank">application program interfaces</a>) connect one app to another on your smartphone, O-RAN serves as an API for the network itself. And because of O-RAN’s open standards, a wireless network becomes programmable, vendor-neutral, and open to custom applications called <a href="https://www.i14y-lab.com/glossary/xapp#:~:text=An%20xApp%20is%20a%20software,optimizing%20RAN%20functions%20and%20resources." rel="noopener noreferrer" target="_blank">xApps</a>.</p><p>To test our proof-of-concept framework, I have been part of a team simulating five minutes of O-RAN V2X network traffic over one square kilometer of urban area, using real buildings and real-world road layouts from <a href="https://www.openstreetmap.org/" rel="noopener noreferrer" target="_blank">OpenStreetMap</a> and traffic patterns generated by the modeling package <a href="https://en.wikipedia.org/wiki/Simulation_of_Urban_MObility" rel="noopener noreferrer" target="_blank">SUMO</a>. The simulations assumed a traffic density of 50-70 vehicles per kilometer—not rush hour but not light traffic either. In our simulation, we assumed vehicles communicated via a millimeter-wave frequency of 28 gigahertz and that each component of our O-RAN V2X system had its own dedicated xApp.</p><p>Taken together, these inputs—real geometry, real traffic, and each vehicle’s live GPS position—constitute what network researchers call a <a href="https://spectrum.ieee.org/tag/digital-twins" target="_self">digital twin</a> of the urban environment. That’s a virtual replica detailed enough for the network to reason about the physical world in real time.</p><p>This virtual world gave us a real result, too.</p><p>The simulations, published <a href="https://ieeexplore.ieee.org/document/10937198" rel="noopener noreferrer" target="_blank">recently in <em><em>IEEE Network</em></em></a>, revealed that existing V2X standards—in which cars uncoordinatedly spit out messages into the network—result in signals “talking” over each other some 80-100 percent of the time. However, using O-RAN signal coordination, the message “collision” rate dropped to near zero.</p><p>And that matters because a seized-up V2X network doesn’t just fail quietly. It can fail in ways that might make a road turn treacherous. </p><h3>How O-RAN Can Coordinate V2X Traffic</h3><p>High-frequency data links between cars are already difficult to maintain, even on a clear day with no buildings or city infrastructure getting in the way.</p><p>Yet, in this situation, existing V2X networks leave a car to conduct blind searches for each dropped signal beam. Traveling at highway speeds, that search takes long enough for the surrounding world to change completely.</p><p>An O-RAN network continuously <a href="https://www.o-ran.org/specifications" rel="noopener noreferrer" target="_blank">tracks signal conditions across the network</a>, and in O-RAN V2X simulations, we also gave the network access to a detailed map of the urban environment—building positions, road geometry, intersection layouts—combined with each vehicle’s GPS trajectory. Together, these parameters let the <a href="https://en.wikipedia.org/wiki/OSI_model#Layer_3:_Network_layer" rel="noopener noreferrer" target="_blank">network’s control layer</a> predict where and when a signal link is about to fail and instruct each car’s antenna to adjust before the connection drops.</p><p>Signal pointing is one failure mode. Losing the connection entirely—because no direct path exists at all—is another.</p><p>Consider, for instance, a crossroads of two busy streets, with a few alleys and parking lots adding to the list of potential dangers.</p><p>If a signal from car A cannot reach car B directly, or if the path length is too far for an individual beam to travel, the signal must find an intermediary car or stationary sensor nearby that can pass along the message. And existing V2X standards are slow and reactive—polling potential relay vehicles one-by-one: <em><em>Are you available? Can you redirect this message?</em></em></p><p>By contrast, O-RAN keeps a running graph of optimized message routes, accounting for a range of real-world constraints. So when an O-RAN link fails (whether that link is direct from sender to receiver—or indirect), the system already has a reroute mapped out.</p><p>This is partly why we included “<a href="https://www.mdpi.com/1424-8220/23/9/4203" rel="noopener noreferrer" target="_blank">multi-hop routing</a>” in the O-RAN V2X simulations.</p><p>Multi-hop V2X O-RAN routing complicated three separate elements of the simulation: for each signal’s middleman (some cars may be ideally positioned to relay a signal from car A to car B, but we made the simulation neglect any cars that were also overwhelmed with their own signals and signal-processing needs); for each signal’s strength (we required that every intermediate link be able to maintain a stable network connection, factoring in distance and traffic conditions); and for each signal’s latency (we required a realistic accounting for added signal latency time for each additional hop in a multi-hop routing).</p><p>And with each added complication, O-RAN V2X multi-hop routing continued to extend the network’s capacity from 25 percent of nearby cars connected (without multi-hop) to nearly 100 percent (with multi-hop). </p><p>These complications, at least at the simulation level, did not slow down the V2X network. </p><h3>How Could O-RAN Ever Be Scaled Up for the Real World?</h3><p>We are in touch with potential collaborators and institutions to develop testbeds, prototype hardware, and tester vehicles for potential proving grounds. <a href="https://www.titech.ac.jp/english" rel="noopener noreferrer" target="_blank">The Institute of Science Tokyo</a>, for instance, has already expressed interest in working on some of these early-stage problems.</p><p>To date, our published research on O-RAN V2X has centered around a computer simulation only. Real-world hardware will undoubtedly surface challenges our simulation could not. So, questions of network latency and the computational overhead needed for O-RAN V2X signaling remain as yet unresolved.</p><p>Plus, concerns about full interoperability and realistic security will each demand their own investigations. After all, no one will trust a V2X network to do anything if that network’s cyber vulnerabilities haven’t been anticipated and patched in advance.</p><p>Realizing the O-RAN V2X vision will require progress on multiple fronts simultaneously. On the standards side, O-RAN’s vehicular extensions—the interfaces that allow vehicles to participate in the network as managed elements rather than passive users—would ultimately need to be formally adopted by the <a href="https://www.o-ran.org/" rel="noopener noreferrer" target="_blank">O-RAN Alliance</a> and recognized by <a href="https://www.3gpp.org/specifications-technologies/releases/release-14" rel="noopener noreferrer" target="_blank">3GPP’s V2X specifications</a>. That process takes years.</p><p>On the industry side, there is a more immediate problem that our architecture is already positioned to solve: interoperability.</p><p>Today, a car made by one manufacturer cannot necessarily parse V2X sensor data sent from a car made by another. Firmware is proprietary; data formats differ. But an O-RAN control layer would act as a universal translator—normalizing each vehicle’s data into a common format and accelerating a push toward true multi-platform vehicle-to-vehicle communications. A more widespread and truly universal standard would, by itself, represent a substantial step forward for V2X.</p>]]></description><pubDate>Fri, 07 Aug 2026 13:00:01 +0000</pubDate><guid>https://spectrum.ieee.org/v2x-technology-5g-open-ran</guid><category>Connected-vehicles</category><category>V2x</category><category>Vehicle-to-everything</category><category>5g</category><category>O-ran</category><dc:creator>Francesco Linsalata</dc:creator><media:content medium="image" type="image/jpeg" url="https://spectrum.ieee.org/media-library/an-illustration-of-two-cars-with-cell-towers-on-top-communicating-via-speech-bubbles.jpg?id=67571736&amp;width=980"></media:content></item><item><title>IEEE Course Teaches How to Use AI to Modernize Power Grids</title><link>https://spectrum.ieee.org/ieee-course-ai-power-grids</link><description><![CDATA[
<img src="https://spectrum.ieee.org/media-library/conceptual-illustration-of-a-man-holding-a-ginormous-lightbulb-with-ai-written-on-it.jpg?id=67568096&width=1245&height=700&coordinates=0%2C187%2C0%2C188"/><br/><br/><p>Today’s U.S. electrical grid, among the largest, most complex systems ever built, is operating at its limit. The combination of rapid industrial growth, more frequent extreme weather, and a record surge in electricity use has <a href="https://www.energy.gov/policy/electricity-demand-growth-resource-hub" rel="noopener noreferrer" target="_blank">pushed the grid to its breaking point</a>, according to the <a href="https://www.energy.gov/" rel="noopener noreferrer" target="_blank">U.S. Department of Energy</a>.</p><p>Built decades ago for a more predictable world in which power came mostly from centralized coal or gas plants and electricity use grew at a steady pace, the grid faces <a href="https://spectrum.ieee.org/data-centers-grid-instability" target="_self">unanticipated strain</a> due in part to growing demand from data centers. The jobs of professionals managing the infrastructure have evolved from traditional engineering tasks to complex, fast-moving challenges.</p><p>Industry reports show that millions of modern digital sensors, smart meters, and grid monitors are generating nonstop waves of information. The sheer volume of data requires instant, automated computer analysis because human operators cannot process it fast enough.</p><p>Pressure on utilities stems from two sources: a spike in electricity demand and a shift in how power is generated.</p><p>An example of the operational strain can be seen at the regional level. With the recent deployment of artificial intelligence tools and high-performance computing, data centers require <a href="https://spectrum.ieee.org/dcflex-data-center-flexibility" target="_self">immense amounts of energy</a> to operate. The largest power transmission utility in Texas recently reported a <a href="https://www.cnbc.com/2025/12/12/ai-data-center-flood-texas-on-massive-scale.html" rel="noopener noreferrer" target="_blank">staggering 220 gigawatts</a> of new connection requests, driven largely by a surge in AI and cloud-computing facilities, according to a <a href="https://www.cnbc.com/" rel="noopener noreferrer" target="_blank">CNBC </a>report.</p><p>Alongside the rise in regional demand, global energy networks are absorbing an unpredictable variety of weather-dependent renewable energy such as wind and solar. The switch creates a volatile operating environment wherein supply and demand are balanced, second by second, to prevent blackouts.</p><p>The challenges are compounded by the vulnerability of the grid’s physical and digital framework.</p><p>More-frequent severe weather events cause costly disruptions, such as the devastating winter freeze that crippled the Texas grid and record-breaking heat waves that have overloaded transformers.</p><p>Simultaneously, the energy networks’ digital architecture faces threats. As utilities replace outdated analog equipment with smart meters and control systems, they are increasingly vulnerable to <a href="https://spectrum.ieee.org/power-grid-attack-security-gridex" target="_self">cyberattacks</a>.</p><p>To overcome physical and digital vulnerabilities, grid reliability organizations, such as those conducting North American security simulations like <a href="https://spectrum.ieee.org/power-grid-attack-security-gridex" target="_self">GridEx</a>, emphasize that the grid must become smarter, more agile, and completely automated. Energy researchers are noting that the key to this change lies in integrating AI across every layer of utilities’ operations.</p><h2>The AI imperative</h2><p>According to energy industry experts, using AI to manage power systems is no longer a futuristic research project; it has become a baseline operational necessity. Grid analysts emphasize that traditional grid-planning methods are too slow to handle <a href="https://spectrum.ieee.org/ai-designed-thermoelectric-generator" target="_self">rapid energy dynamics</a> or to balance volatile renewable energy in real time within decentralized power systems such as microgrids.</p><p>AI can fill the gap by processing vast amounts of data instantly. Machine learning algorithms can quickly analyze information from thousands of sensors, historical usage patterns, and weather forecasts to predict issues before they happen.</p><p>An industrial digitization study conducted by <a href="https://www.mckinsey.com/~/media/McKinsey/Business%20Functions/McKinsey%20Digital/Our%20Insights/Digital%20in%20industry%20From%20buzzword%20to%20value%20creation/Digital-in-industry-From-buzzword-to-value-creation.pdf" rel="noopener noreferrer" target="_blank">McKinsey & Co.</a> indicated that integrating advanced data and automation across infrastructure networks could reduce system design errors, decrease equipment downtime by up to 50 percent through predictive maintenance, and extend the lifespan of power machinery by up to 40 percent.</p><p>From forecasting energy spikes to automatically fixing localized voltage drops, AI acts as the digital backbone of a self-healing grid, experts say. Deploying the complex systems requires a new workforce: power engineers who understand data science, as well as data scientists who understand electricity.</p><h2>Upgrading the Workforce</h2><p>To bridge the gap between groundbreaking AI research and practical field deployment, <a href="https://ea.ieee.org" rel="noopener noreferrer" target="_blank">IEEE Educational Activities</a>, in partnership with the <a href="https://ieee-pes.org/" rel="noopener noreferrer" target="_blank">IEEE Power & Energy Society</a>, has launched the online <a href="https://iln.ieee.org/public/contentdetails.aspx?id=48A92EF8188E4D2E8331E1381CAF98E7&utm_campaign=InstArticle&utm_source=ieee-spectrum&utm_medium=article&utm_content=InstArticle" rel="noopener noreferrer" target="_blank">Artificial Intelligence for Power and Energy Systems</a> course program.</p><p>The program explores core challenges threatening modern utilities.

Many patients can access their electronic medical records from home.</p><p>The platforms exist thanks to pioneering efforts such as the <a href="https://dl.acm.org/doi/pdf/10.1145/89482.89511" rel="noopener noreferrer" target="_blank">Medical Information System</a> (MIS-I). The first hospital-wide computer system, it was developed in the 1960s by <a href="https://www.lockheedmartin.com/en-us/index.html" rel="noopener noreferrer" target="_blank">Lockheed Martin</a> (then known as Lockheed Missiles and Space Co.) in partnership with <a href="https://www.elcaminohealth.org/" rel="noopener noreferrer" target="_blank">El Camino Hospital</a>, in Mountain View, Calif. Doctors and nurses used MIS-I (pronounced <em><em>miss-ONE</em></em>) to admit patients, order lab work and imaging, schedule follow-up appointments, and issue hospital bills, according to a 1973 article published by <a href="https://www.datamation.com/" rel="noopener noreferrer" target="_blank"><em><em>Datamation</em></em></a>.</p><p>Although many people now know how to type on a keyboard, in the 1960s, most did not. Therefore, MIS-I included a light pen, which worked like a stylus for today’s touchscreens.</p><p>MIS-I was recognized as an <a href="https://ieeemilestones.ethw.org/Main_Page" rel="noopener noreferrer" target="_blank">IEEE Milestone</a> during a ceremony on 14 May at El Camino Hospital. The <a href="https://ieeescv.org/" rel="noopener noreferrer" target="_blank">IEEE Santa Clara Valley Section</a> sponsored the Milestone.</p><p>“The medical information system was more than a technological breakthrough; it was proof of what can happen when clinicians, engineers, administrators, and community leaders unite around a common goal: improving care for patients,” <a href="https://www.elcaminohealth.org/about-us/hospital-leadership/executive-team/dan-woods" rel="noopener noreferrer" target="_blank">Dan Woods</a> said at the event. He is chief executive of <a href="https://www.elcaminohealth.org/" rel="noopener noreferrer" target="_blank">El Camino Health</a>, the nonprofit organization that maintains the hospital.</p><p>“This pioneering work helped establish the foundation for the modern medical informatics industry,” Woods said. “The legacy of Lockheed’s innovation continues to benefit patients and health care providers around the world, making this achievement truly worthy of lasting recognition.”</p><h2>Bringing technology into clinical care</h2><p>Prior to Lockheed’s effort, health records remained paper-based. They often were stored in dedicated rooms within the hospital. Files were kept in heavy-duty manila folders organized on mechanized open-shelf filing systems, revolving rotary files, or locked steel filing cabinets, according to <a href="https://www.eojohnson.com/blog/digitizing-medical-records" rel="noopener noreferrer" target="_blank">EO Johnson Business Technologies</a>. The process of retrieving a patient’s medical history was cumbersome and could hamper decision-making in a life-or-death situation. Paper records were prone to human error, according to an <a href="https://www.ehrinpractice.com/problem-with-paper-charting.html" rel="noopener noreferrer" target="_blank">EHR in Practice article</a>. In addition, upkeep could be costly due to administrative expenses such as transcribing doctors’ notes, storing patient charts, adding medical codes, and managing insurance claims.</p><p>Companies and universities including <a href="https://www.ge.com/about-us" rel="noopener noreferrer" target="_blank">General Electric</a>, <a href="https://www.ibm.com/us-en" rel="noopener noreferrer" target="_blank">IBM</a>, and <a href="https://www.harvard.edu/" rel="noopener noreferrer" target="_blank">Harvard</a> began exploring how to use computers to improve clinical care. They developed several systems for hospital laboratories to track test orders and results, as explained in the <a href="https://ethw.org/Milestones:Pioneering_Medical_Information_System,_1965-1974" rel="noopener noreferrer" target="_blank">Milestone webpage</a>.</p><p>In 1964 Lockheed was looking to diversify its portfolio, <a href="https://www.linkedin.com/in/melville-hodge-90a48b77/" rel="noopener noreferrer" target="_blank">Melville Hodge</a>, who helped lead the MIS development, said at the dedication ceremony. The company decided to apply its expertise to health care, and later that year this focus-area became part of a new information systems division.

Below that monitor was a keyboard, and to its right was a printer. Doctors and nurses would swipe their ID badge to access the system, then use the keyboard to put information into the patient’s file or send a request to a pharmacy or laboratory. They also could print documents.</p><p>But one problem kept cropping up: Most doctors didn’t know how to type. The computer mouse was still in its infancy, and Hodge suspected it would not solve the problem, according to a video shown at the dedication ceremony. Instead, he “borrowed technology from a then-secret satellite program,” he said.</p><p>That technology was the light pen, which was used with <a href="https://ethw.org/Milestones:Whirlwind_Computer,_1944-59" rel="noopener noreferrer" target="_blank">MIT’s Whirlwind Computer</a> in the 1950s.</p><p>“The insight that physicians could not and would not learn to type, combined with the innovative solution of light pen interaction, transformed an impossible dream into practical reality,” the Milestone proposers wrote.</p><p>To display text, the system used matrix programming, a 2D data structure consisting of rows and columns. Using the light pen, a doctor or nurse would select text from a list of general categories on the monitor. The options included the patient’s personal and medical information, family medical history, current illness, and physical exam findings, according to a 1968 article in the medical journal <a href="https://jamanetwork.com/journals/jama" rel="noopener noreferrer" target="_blank"><em><em>JAMA</em></em></a>. The computer would display the requested information or list the next steps to complete tasks such as sending a prescription to a pharmacy. The keyboard remained part of the setup because it could allow users to input new information and update patient records.</p><p>To further develop the system, they submitted a proposal to the U.S. Department of Health, Education, and Welfare (now split into the Departments of <a href="https://www.hhs.gov/" rel="noopener noreferrer" target="_blank">Health and Human Services</a> and <a href="https://www.ed.gov/" rel="noopener noreferrer" target="_blank">Education</a>) to secure additional funding, but it was rejected.</p><p><a href="https://www.nytimes.com/1993/10/02/obituaries/herschel-j-brown-88-a-leader-at-lockheed.html" rel="noopener noreferrer" target="_blank">Herschel Brown</a>, Lockheed’s executive vice president, and <a href="https://www.almanacnews.com/morgue/2004/2004_01_28.obits.shtml" rel="noopener noreferrer" target="_blank">Kenneth Larkin</a>, its director of information systems, decided to fund its commercial development, Hodge wrote.</p><p>When the company’s contract with the Mayo Clinic ended, the Lockheed team returned to Sunnyvale, California to refine, test, and deploy the system at El Camino Hospital.</p><p>“I admire <a href="https://obits.cleveland.com/person/R.-Edwin-Hawkins-30037082" rel="noopener noreferrer" target="_blank">Ed Hawkins</a>, who was its first administrator, for having the courage to take on this kind of project while running a hospital that was only four years old at the time,” Hodge said at the dedication ceremony.</p><h2>Making MIS-I a commercial success</h2><p>Starting in 1968, early prototypes were installed in the hospital’s M.D. lounges and nursing station at El Camino Hospital. The organizations worked to configure the system so it met the hospital’s needs.</p><p>By 1969, a number of monitors had been installed, including in admissions, pharmacy, and radiology. The information from all the connected machines was stored in a data center housed in a separate location outside the hospital.</p><p>In 1971 Lockheed encountered difficulties with its <a href="https://www.af.mil/About-Us/Fact-Sheets/Display/Article/1529718/c-5-abc-galaxy-and-c-5m-super-galaxy/" rel="noopener noreferrer" target="_blank">C-5A</a> and <a href="https://en.wikipedia.org/wiki/Lockheed_L-1011_TriStar" rel="noopener noreferrer" target="_blank">L-1011</a> aircraft programs, according to Hodge. The company was forced to curtail discretionary new business programs including MIS-I. The program was sold to <a href="https://www.technicon.com/" rel="noopener noreferrer" target="_blank">Technicon</a> of Tarrytown, N.Y., a leader in clinical laboratory automation.</p><p>The medical information system business operated independently as a subsidiary unit, and the transition marked the beginning of MIS-I’s commercial expansion.</p><p>That same year, MIS-I went live for hospital-wide use. Physicians’ orders were communicated to other departments, test results and radiology reports were retrieved, and nursing care planning and documentation were available, according to the <em><em>Journal of Nursing Scholarship</em></em>. MIS-I supported most information handling for nurses, physicians, and other medical personnel in the hospital.</p><p>But the change was not welcomed by all, according to the video about the technology. Nurses tended to praise the system, but many doctors had a hard time transitioning from paper to computers. They complained they were “spending more time fighting a machine” than interacting with their patients, according to the video. Some even retired to avoid learning the system. But nurses fought to keep it, emphasizing to doctors how much it improved patient care.</p><p>In 1974 El Camino Hospital held a vote of medical staff to determine whether to keep the system or return to paper-based records. About 60 percent of doctors and more than 90 percent of nurses voted in favor of keeping it, according to the Milestone webpage.</p><p class="pull-quote">“The medical information system was more than a technological breakthrough; it was proof of what can happen when clinicians, engineers, administrators, and community leaders unite around a common goal: improving care for patients.” <strong>—Dan Woods, El Camino Health CEO</strong></p><p>In 1975 nonprofit <a href="https://www.battelle.org/" target="_blank">Battelle</a> of Columbus, Ohio, evaluated how well the system was working for El Camino Hospital. It <a href="https://ethw-images.s3.us-east-va.perf.cloud.ovh.us/ieee/4/4f/Technicon_19751219_ECH_Battelle.pdf" target="_blank">found that MIS-I</a> reduced the time nursing staff spent on clerical tasks, improved communications among departments, and facilitated better planning of patient care. The survey also showed that more readily available, complete, and accurate information was being used to administer care and monitor patient progress, according to the report.</p><p>By 1993, the technology was installed in more than 200 hospitals in the United States, Canada, and Europe, according to the Milestone entry.</p><p>El Camino Hospital used MIS-I for 34 years, until its decommissioning in 2005. It was initially replaced by <a href="https://www.biospace.com/b-eclipsys-sunrise-clinical-manager-tm-b-3-5-xa-tm-activated-by-b-cottage-health-system-b-santa-barbara" rel="noopener noreferrer" target="_blank">Eclipsys Sunrise XA</a> and then ultimately by Epic.</p><h2>Honoring an IEEE Milestone</h2><p>The dedication ceremony brought together IEEE leaders, hospital staff, and government representatives. Hodge and his family also attended. IEEE President-Elect <a href="https://spectrum.ieee.org/2026-ieee-president-elect-gostin" target="_self">Jill Gostin</a> made a presentation about IEEE, and Brian Berg of the IEEE History Committee discussed the organization’s Milestone program.</p><p>Hodge participated in a Q&A session with <a href="https://www.elcaminohealth.org/about-us/hospital-leadership/executive-team/debbi-muro" rel="noopener noreferrer" target="_blank">Deb Muro</a>, chief information officer of El Camino Health. He told a story about the early days of MIS-I that he said he will never forget. During a hospital board meeting at which physicians were complaining about the system, an announcement was made over the hospital’s public address system that MIS-I wasn’t working.</p><p>“I had to ignore it to survive,” Hodge said, laughing. “As physicians got more used to it, and with a phenomenal poking from the nurses, doctors who wouldn’t use it were forced to.”</p><p>A bronze plaque recognizing the MIS-I as an IEEE Milestone has been installed in the lobby of the hospital in Mountain View. The plaque reads:</p><p><em>From 1965 to 1974, the first hospital-wide computerized medical information system was created by Lockheed Missiles and Space Co. in partnership with El Camino Hospital. Innovative light-pen terminals enabled physicians and staff across all departments to efficiently and accurately access patient data and enter work orders. By providing immediate feedback and seamless communication, it reduced costs and errors, improved safety and outcomes, and led the way to modern medical and clinical informatics.</em></p><p>Reviewed by the <a href="https://history.ieee.org/about/ieee-history-committee/" rel="noopener noreferrer" target="_blank">IEEE History Committee</a> and approved by the <a href="https://www.ieee.org/about/corporate/board" rel="noopener noreferrer" target="_blank">IEEE Board of Directors</a>, IEEE Milestones recognize outstanding technical developments around the world that are at least 25 years old.

Other applications driving this demand include wind farms, data centers, and server farms, to name a few. As the interest for high-voltage electronics increases, the risks associated with their sudden failure must be considered. </p><p>Much of what causes high-voltage equipment to malfunction can be linked to the conditions of the climate in which it operates. Specifically, condensation on electronic surfaces caused by humidity can lead to corrosion, which can result in stray leak current and dendrite shorting during Electrochemical Migration (ECM). </p><p>Predicting, mitigating, and helping proactively design to account for corrosion is the focus of the <a href="https://celcorr.dtu.dk/" target="_blank">Centre for Electronic Corrosion (CELCORR)</a> research group at the <a href="https://www.dtu.dk/english" target="_blank">Technical University of Denmark (DTU)</a>. The group’s researchers are working with industry partners to develop models and simulation apps that will help in building robust electronics designs. Their goal is to develop knowledge that can be used for manufacturing electronics to withstand humid operating conditions.</p><h2>Electronic Failure: “It’s Not the Heat; It is the Humidity”</h2><p>Automotive electrification and renewable energy systems rely on electronics at all stages of the energy chain. When these electronics, such as the example PCB in Figure 1, are exposed to the effects of moisture, they can become potential failure points.</p><p> “Anywhere you are producing, converting, transporting, and using energy, you need these high-power electronic systems that get affected by the humidity,” explained <a href="https://orbit.dtu.dk/en/persons/rajan-ambat/" target="_blank">Dr. Rajan Ambat</a>, DTU professor and manager of CELCORR. Ambient moisture can seep into the devices and machines that require these electronics and cause unexpected functional issues through corrosion. When these electronics are involved in particularly high-voltage applications (such as wind farms, data centers, electric vehicles, and server farms), failure due to humidity exposure can even lead to fire.</p><p>“There might be a situation where somebody installs a solar panel near the seashore or in an area with high humidity, and within a short period of time, a conducive condition forms inside the electronics that results in a failure,” Ambat said. “This is why we need to understand exactly how the conducive condition of condensation is created, when the condition is created, and how the system is failing.”</p><p class="shortcode-media shortcode-media-rebelmouse-image"> <img alt="Heatmap of electrolyte potential and tangential current density on a metal plate" class="rm-shortcode" data-rm-shortcode-id="e93a191d5911faa67541c2d4ee4964df" data-rm-shortcode-name="rebelmouse-image" id="9f056" loading="lazy" src="https://spectrum.ieee.org/media-library/heatmap-of-electrolyte-potential-and-tangential-current-density-on-a-metal-plate.png?id=67522194&width=980"/><small class="image-media media-caption" placeholder="Add Photo Caption...">Figure 1. The electrolyte potential and current density distributions on a PCB surface (with pinholes).</small><small class="image-media media-photo-credit" placeholder="Add Photo Credit...">CELCORR/DTU</small></p><p><span>Identifying corrosion as the underlying cause of some electronic failures is still a challenge. “Fifty percent of failures in electronics are currently branded with an unidentified root cause,” Ambat explained. “When engineers open up the system, they do not realize that the failure was due to corrosion, because moisture disappears without leaving any sign of corrosion unless there is ECM dendrite formation.” </span></p><p><span>This lack of awareness was a strong motivator for CELCORR, which turned to multiphysics simulation as a supplementary tool to help its partner organizations to better predict humidity-related issues at the design stage.</span></p><h2>Modeling Moisture and Measuring Parameter Changes in PCBs</h2><p>CELCORR believes the best way to identify and avoid electronic failures is to build more effective designs that better prevent corrosion from developing or can withstand a higher humidity load. Its research team applies its expertise in modeling to generate simulation apps that will help partner industries to evaluate safe designs for humidity robustness.</p><p>“We are at the intersection of materials science and the electronics industry. We work as a bridge between materials and electronics disciplines, using both kinds of language,” Dr. Anish Rao Lakkaraju, a postdoctoral researcher at CELCORR, explained.</p><p>To understand potential design issues, Ambat emphasized the importance of virtually breaking down systems to identify where problems may arise. “We need simulation software to analyze potential uses of designs and whether new designs are good or bad,” Ambat said.</p><p class="pull-quote"><span>Researchers at the Technical University of Denmark (DTU) are using simulation apps to predict corrosion and design electronics proactively to mitigate or withstand its effects.</span></p><p><span>Using the COMSOL Multiphysics</span><span> software for investigation, the CELCORR research team together with other research partners (Aalborg University) built an example model with a simple PCB geometry that matched both its test circuit boards as well as the design of a device used by one of its partner companies. The team then added a water film layer on top to act as the relative humidity. From there, the team could introduce variation. </span><span>“We change the layout, geometry, distance between electrodes, thickness of the water film, and conductivity of the water film depending on the conditions,” Ambat said.</span></p><p>Ambat and his team generate data on the effect of these variations and can identify which has the greatest impact on the device’s performance and whether any alterations can improve the device’s anticorrosion robustness. “We assume there is condensation forming on the electronic surfaces (Figure 2) and compute the electrochemical leak current for different design elements,” Ambat said. “The value of the computed electrochemical current between the parts will give us an indication of whether the PCB will be affected or not.”</p><p class="shortcode-media shortcode-media-rebelmouse-image"> <img alt="Finite-element contour map of tangential electrolyte current density in a cell housing" class="rm-shortcode" data-rm-shortcode-id="ccb9635dd389dfed1512e6ba97b5ec58" data-rm-shortcode-name="rebelmouse-image" id="150b7" loading="lazy" src="https://spectrum.ieee.org/media-library/finite-element-contour-map-of-tangential-electrolyte-current-density-in-a-cell-housing.png?id=67522196&width=980"/><small class="image-media media-caption" placeholder="Add Photo Caption...">Figure 2. A 10-µm water film condensation effect on an example PCB.</small><small class="image-media media-photo-credit" placeholder="Add Photo Credit...">CELCORR/DTU</small></p><p><span>Altering the design elements and solving the model equations again and again allows the team to better understand what makes a design effective. “Now, we are at the current form of the model, and we are quite happy with where the physics are at this point,” Lakkaraju said. This modeling, however, was just the first part of CELCORR’s overarching goal of illuminating the destructive potential of corrosion in electronics and the best ways to avoid it.</span></p><h2>Using Simulation Apps to Test Real-World Designs</h2><p>To open up and ease access to these models, CELCORR used the Application Builder in COMSOL Multiphysics to create simulation applications for the members of the industrial consortium. Built with a simple 3D circuit board geometry with two oppositely biased electrodes and a water layer to replicate corrosion-causing moisture, the apps provide a pared-back, straightforward interface where users can vary model inputs. “We focused on fundamental aspects,” Lakkaraju said. “We boiled down our partners’ overarching concerns to create two apps with very simple geometries and the simplistic stuff that can be varied over multiple parameters.”</p><p>The simple simulation apps shown in Figures 3 and 4 are designed to show companies how the distance between the electrodes and the thickness of the moisture layer affect the leak current through the water film depending on different parameters. By analyzing multiple design elements and parameters, users can determine the relative benefits of certain design elements on the humidity robustness. “The apps we have built have really helped because they give the electronics engineers a plug-and-play sort of approach,” Lakkaraju explained.</p><p class="shortcode-media shortcode-media-rebelmouse-image"> <img alt="COMSOL simulation of electrode surface current density with 3D and 2D heatmap views" class="rm-shortcode" data-rm-shortcode-id="047f8706395c84f3e9c65ce1a612f617" data-rm-shortcode-name="rebelmouse-image" id="8261f" loading="lazy" src="https://spectrum.ieee.org/media-library/comsol-simulation-of-electrode-surface-current-density-with-3d-and-2d-heatmap-views.png?id=67522370&width=980"/><small class="image-media media-caption" placeholder="Add Photo Caption...">Figure 3.

To do this, Ambat and his team are undertaking multiple projects, including actively adding greater complexity to their models. In a tertiary current distribution model they are building, the team is drilling down into each of the basic inputs used in a secondary current distribution model, zooming in to examine the effects of the set of even more detailed inputs each basic input comprises.</p><p>“The next point is to study what each of these detailed inputs does,” Lakkaraju said. In particular, the team is examining mass transport properties and the chemical reactions’ rate constants.</p><p>In addition to these ongoing studies, CELCORR is expanding the scope of its research to investigate corrosion in high-power, high-voltage systems. Thanks to a 2024 grant from the Grundfos Foundation, CELCORR was able to establish the Centre for Climate Robust Electronics Design (CRED). The center’s lab facilities and expertise are being developed to address the humidity-robustness requirements of today’s high-voltage and high-power electronic equipment. “Using CELCORR’s uniquely deep understanding of materials and corrosion, we are equipped to find the root cause and provide knowledge for environmentally robust designs,” said Ambat.</p><p>For all of its investigation, CELCORR continues to rely on the agility of the COMSOL Multiphysics software. As Lakkaraju explained, “It is really quite nice how a model can be adapted to a variety of combinations of materials, geometries, and parameters and how the software allows you to keep building on from there.”</p>]]></description><pubDate>Mon, 03 Aug 2026 11:38:22 +0000</pubDate><guid>https://spectrum.ieee.org/electronics-corrosion-multiphysics-simulation</guid><category>Electronics</category><category>Multiphysics-simulation</category><category>Electronic-failures</category><category>Corrosion</category><category>Comsol</category><dc:creator>Joseph Carew</dc:creator><media:content medium="image" type="image/png" url="https://assets.rbl.ms/67522155/origin.png"></media:content></item><item><title>This Hi-Fi Tape Recorder Changed Radio Forever</title><link>https://spectrum.ieee.org/magnetophon-laugh-track</link><description><![CDATA[

The hit of the Berlin Radio Show when it debuted in 1935, it was developed by the German electronics manufacturer AEG. The magnetic tape was produced by I.G. Farben (now known as BASF).</p><p class="shortcode-media shortcode-media-rebelmouse-image rm-float-left rm-resized-container rm-resized-container-25" data-rm-resized-container="25%" style="float: left;"> <img alt="Black and white photo of a balding white man with a mustache and pince nez.

In the early 1920s, Pfleumer was working on industrial paper products in Dresden. At the time, fancy cigarettes had gold leaf to decorate the tip. Cheaper manufacturers achieved a similar effect using colored paper, but the dye could stain smokers’ lips, and no one wanted that. Pfleumer devised a less expensive process using powdered bronze to simulate the gold band.</span></p><p>Pfleumer didn’t work in the recording industry, but he was familiar with the technology of electromechanical recording, which was done on metal wire—a 1898 invention of the Danish engineer Valdemar Poulsen. Pfleumer thought he could do something similar with paper by replacing his powdered bronze with a magnetized material. He patented his “sounding paper” in 1928 and also invented an audio tape recorder to go with it. The sound quality wasn’t great, and the paper tore easily, but it was the start of a promising idea. Two points in its favor: The paper could be sliced, allowing edits, and it could be erased and re-recorded over.</p><p>Pfleumer knew he needed to partner with a larger company to commercialize his idea, and so he signed a contract with AEG in 1932. Hermann Bücher, chairman of the AEG board of directors, took a personal interest in the project, helping shepherd it to completion. Although AEG originally planned on developing both a recorder and the tape, it didn’t take long for Bücher to reach out to his friend Wilhelm Gaus, managing director at I.G. Farben. AEG developed the hardware, while I.G. Farben worked on the tape.</p><p>The two teams dubbed their product the Magnetophon, or magnetic phonograph, and planned on launching it at the 1934 Berlin Radio Show to compete directly with machines that recorded on steel tape or wire. But the product wasn’t quite ready. Two days before the show, they canceled the debut. </p><p>A year later, the bugs had been worked out. The Magnetophon’s introduction at the 1935 show was a resounding success. AEG fielded inquiries for many variations on the recorder, including one that combined the recorder with a telephone, a player for prerecorded music, and a special version to add artificial reverberation for recording open-air concerts. Over the next three years, AEG developed several iterations, resulting in the Magnetophon K4 in 1938, its first commercially successful tape recorder.</p><p>The K4 eliminated the hiss and distortion that magnetic recordings previously suffered from by incorporating AC bias, which added a high-frequency signal, typically around 40 to 150 kilohertz, to the recording. Inaudible to the human ear, the signal reduced distortion, especially when recording quieter passages. The fidelity of the Magnetophon was such that radio listeners couldn’t distinguish between live broadcasts and prerecorded performances.</p><h2>The Magnetophon During and After the War</h2><p><span>This is where the Nazis come in. Adolf Hitler and his propaganda minister, Joseph Goebbels, understood the power of radio. The Magnetophon became a powerful tool for both political messaging and military strategy. Because the device could record and play back sound at the same quality as a live radio broadcast, it allowed Hitler’s recorded speeches to be aired from one radio station while the dictator was in another part of the country. This made it more difficult for the Allies to pinpoint his location.</span></p><p class="ieee-inbody-related">RELATED: <a href="https://spectrum.ieee.org/inside-the-third-reichs-radio" target="_self">Inside the Third Reich’s Radio</a></p><p>Meanwhile, World War II disrupted the exchange of technical information and prevented Americans from learning about the Magnetophon until after the war.

After the war, he got approval [bottom] to ship two of the disassembled machines and reels of magnetic tape back to the U.S.</small><small class="image-media media-photo-credit" placeholder="Add Photo Credit...">Top: Pavek Museum; Bottom: Richard L.

Engel’s account in the book <em><em>Magnetic Recording: The First 100 Years</em></em>, which provides a wealth of detail about the Magnetophon. Among other things, Engel notes that the AEG affiliate in Schenectady, N.Y., received a Magnetophon in November 1937, well before the United States entered the war, and AEG engineers demonstrated it for their colleagues at nearby General Electric. The GE engineers dismissed the technology out of hand, though, and so Americans had to wait until after the war for the Magnetophon to be reintroduced.</p><p>We have electrical engineer <a href="https://magazine.scu.edu/magazines/summer-2006/the-man-behind-the-sound/" target="_blank">John T. “Jack” Mullin</a> to thank for that reintroduction. Mullin served in the U.S. Army Signal Corps, stationed in the United Kingdom and Paris during the war, and he liked listening to the radio. He realized that “live” orchestral broadcasts coming from Germany in the middle of the night, when no musicians would have actually been in the studio, lacked the telltale hiss and crackle of prerecorded music. Clearly, German engineers had recording technology far superior to the Americans’. </p><p> Sent to Germany at the war’s end, Mullin eventually came across that technology at a radio station, and in 1945 when he returned home to California, he shipped two disassembled Magnetophons, a case of tape, schematic drawings, and the determination to change the U.S. recording industry. </p><h2>Bing Crosby Championed the Magnetophon</h2><p>Enter Bing Crosby. In the 1940s, Crosby was perhaps the most popular performer on the radio. But he was tired of performing two weekly shows three hours apart (one for each coast). He wanted to prerecord his performances and take a break. He sent in his lawyers to talk to executives at NBC, which aired his program. The audio recording technology at the time used vinyl or shellac transcription discs, but radio listeners could hear the pops and hisses and knew it wasn’t live. NBC refused Crosby’s request, and so Crosby took a year off from radio and then signed with the upstart network ABC, which was willing to let him record his shows for later airing. </p><p class="shortcode-media shortcode-media-rebelmouse-image"> <img alt="Black and white photo of two men in suits facing each other and standing in front of radio equipment.

In October 1946, Crosby’s technical producer, Murdo MacKenzie, heard about the demonstrations and arranged one for Crosby at the Metro-Goldwyn-Mayer studios in Hollywood. Crosby was delighted and promptly invested US $50,000 (about $800,000 today) in Ampex, the company working with Mullin to engineer an American version of the Magnetophon. Mullin became Crosby’s chief engineer. 3M developed the magnetic tape.</p><p>In 1947, Crosby became the first major radio star in the United States to prerecord performances. Much of the success was due to the recording equipment, but Mullin was also an excellent editor. Crosby and his team would record multiple takes, and Mullin would deftly splice together the best to create a seamless performance.</p><p class="shortcode-media shortcode-media-rebelmouse-image rm-float-left rm-resized-container rm-resized-container-25" data-rm-resized-container="25%" style="float: left;"> <img alt="Black and white photo of a smiling man in a suit and hat sitting next to a reel to reel tape recorder." class="rm-shortcode" data-rm-shortcode-id="51792aecb456a95cdbdb670621fdcb1b" data-rm-shortcode-name="rebelmouse-image" id="745e9" loading="lazy" src="https://spectrum.ieee.org/media-library/black-and-white-photo-of-a-smiling-man-in-a-suit-and-hat-sitting-next-to-a-reel-to-reel-tape-recorder.jpg?id=67529086&width=980"/> <small class="image-media media-caption" placeholder="Add Photo Caption...">After seeing a demo of the Magnetophon, Bing Crosby invested $50,000 in Ampex, which developed a U.S. version of the tape recorder. </small><small class="image-media media-photo-credit" placeholder="Add Photo Credit...">Cinematic/Alamy</small></p><p>One day a guest told a joke that was uproariously funny, but a little too spicy for radio. Even though the joke couldn’t be aired, the audience’s laughter was worth keeping. Soon, the producers created a whole catalog of different laugh tracks. If a joke didn’t land, it didn’t matter. The editor could just add a laugh in postproduction, from polite titters to hearty guffaws.</p><p>According to Crosby’s daughter Mary, Bing didn’t have a problem with this type of editing. The live audience was immaterial as long as the jokes were funny. But according to Mullin’s daughter, Eve Mullin Collier, the manipulation didn’t sit well with <em><em>her</em></em> father. He disliked the inauthenticity of the moment, of editing joy.</p><p>The history of technology is filled with such episodes of unintended consequences. Mullin admired the Magnetophon precisely because it could faithfully record a performance, an event, a moment in time. He worked tirelessly to refine the machine for the benefit of radio audiences everywhere. And so I understand why its appropriation for capturing canned reactions and manipulating reality must have rankled. He championed the technology, but ultimately it moved beyond his control. </p><p><em><em>Part of a </em></em><a href="https://spectrum.ieee.org/collections/past-forward/" target="_self"><em><em>continuing series</em></em></a><em> </em><em><em>looking at historical artifacts that embrace the boundless potential of technology.</em></em></p><p><em><em>An abridged version of this article appears in the August 2026 print issue as “Birth of the Laugh Track.”</em></em></p><h3>References</h3><br/><p>Luis Felipe Eguiarte Souza, curator at the <a href="https://pavekmuseum.org/" target="_blank">Pavek Museum of Electronic Communication</a>, in St. Louis Park, Minn., first told me about the Magnetophon and its link to the laugh track.

Then in 2005 we decided to do a special report, focusing on the challenges of enterprise software development. I suggested we invite IEEE Life Senior Member <a href="https://spectrum.ieee.org/u/robert-n-charette" target="_self">Robert N. Charette</a>, a self-described risk ecologist, prolific book author, and leading authority on risk management and software engineering, to explore in our pages the myriad reasons software projects fail. His seminal article “<a href="https://spectrum.ieee.org/why-software-fails" target="_self">Why Software Fails</a>” is still read in university engineering classes today. </p><p class="shortcode-media shortcode-media-rebelmouse-image rm-float-left rm-resized-container rm-resized-container-25" data-rm-resized-container="25%" style="float: left;"> <img alt="Older white man with a white beard and glasses." class="rm-shortcode" data-rm-shortcode-id="37a735d53f7a52f5fb654540dfd5f024" data-rm-shortcode-name="rebelmouse-image" id="946ad" loading="lazy" src="https://spectrum.ieee.org/media-library/older-white-man-with-a-white-beard-and-glasses.jpg?id=67541843&width=980"/> <small class="image-media media-caption" placeholder="Add Photo Caption...">IEEE Life Senior Member Robert N.

Charette</small></p><p>It was, as they say, the beginning of a beautiful friendship. I had found my rabbi, one who shared my love of writing. We settled into a rhythm that would last more than 20 years, talking on Friday mornings about a range of topics including the growing ubiquity of software in our lives. </p><p>So when I became <em><em>Spectrum</em></em>’s website editor in 2007, he was the first contributor I tapped to start a regular blog (remember those?). The<em><em> Risk Factor</em></em> was born and over the course of more than 10 years and 1,750 posts, Bob chronicled hundreds of software debacles, culminating in “<a href="https://spectrum.ieee.org/the-making-of-lessons-from-a-decade-of-it-failures" target="_self">Lessons From a Decade of IT Failures</a>,” which won a Jesse H. Neal Award for Best Infographics in 2016. Ironically, yet predictably, those infographics were created in a software package that is no longer supported and thus are lost to the bits of time.</p><p class="shortcode-media shortcode-media-rebelmouse-image"> <img alt="Blue heron with a fish in its beak." class="rm-shortcode" data-rm-shortcode-id="3c28540208ed1e6beda3f245eb07a9d4" data-rm-shortcode-name="rebelmouse-image" id="560cc" loading="lazy" src="https://spectrum.ieee.org/media-library/blue-heron-with-a-fish-in-its-beak.jpg?id=67541851&width=980"/> <small class="image-media media-caption" placeholder="Add Photo Caption...">“I like the expression on the fish just before it’s going to be swallowed by the heron.”</small><small class="image-media media-photo-credit" placeholder="Add Photo Credit...">Robert N. Charette</small></p><p>Bob, however, was not a one-trick pony. In between his full-time job running his two management consultancies and raising a future biochemist and a future civil engineer, his daughters Maura and Megan, he also wrote many deeply reported and insightful articles. These include last year’s “<a href="https://spectrum.ieee.org/electronic-health-records" target="_self">The Doctor Will See Your Electronic Health Record Now</a>,” the eye-opening 12-part series and e-book <a href="https://spectrum.ieee.org/ev-transition-explained-ebook" target="_self"><em><em>The EV Transition Explained</em></em></a>, and my personal favorite “<a href="https://spectrum.ieee.org/automated-to-death" target="_self">Automated to Death</a>,” about the deadly consequences of the automation paradox as manifested by the cyberphysical systems that pilot planes, trains, and automobiles. </p><p class="shortcode-media shortcode-media-rebelmouse-image"> <img alt="Juvenile bald eagle over water, yellow talons extended as it prepares to snag a fish." class="rm-shortcode" data-rm-shortcode-id="59fb0851070219f49af30d572b876bc7" data-rm-shortcode-name="rebelmouse-image" id="93b22" loading="lazy" src="https://spectrum.ieee.org/media-library/juvenile-bald-eagle-over-water-yellow-talons-extended-as-it-prepares-to-snag-a-fish.jpg?id=67541848&width=980"/> <small class="image-media media-caption" placeholder="Add Photo Caption...">“The young bald eagle I photographed in September 2024 had bands that I could read which identified it as a female born in May 2024, near Lexington Park, St. Mary’s County, Maryland, about 65 miles away from where I live.”</small><small class="image-media media-photo-credit" placeholder="Add Photo Credit...">Robert N. Charette</small></p><p>His main goal all along has been to make software visible, as he told me one Friday in July. “Software is all around us, but we don’t recognize it at all,” he said. “I really wanted my stories to help people better understand complex software systems. You can’t see software, you can’t touch it, you can’t taste it. You may feel the consequences of software failure, but you never see the reason itself.”</p><p>When he told me that he was hanging up his hat as a contributing editor to focus on nature photography and to write a handful of fictional trilogies, including one entitled “The STEM Murders” featuring an engineer-turned-detective and <em><em>his</em></em> rabbi, I asked him which of his <em><em>Spectrum</em></em> articles had the biggest impact. </p><p class="shortcode-media shortcode-media-rebelmouse-image"> <img alt="Humming bird feeding from a long red flower." class="rm-shortcode" data-rm-shortcode-id="66a9ecd4251fb7cd155942daf87afc00" data-rm-shortcode-name="rebelmouse-image" id="c1933" loading="lazy" src="https://spectrum.ieee.org/media-library/humming-bird-feeding-from-a-long-red-flower.jpg?id=67541845&width=980"/> <small class="image-media media-caption" placeholder="Add Photo Caption...">“The hummingbird I caught with the yellow of a road curb behind it.”</small><small class="image-media media-photo-credit" placeholder="Add Photo Credit...">Robert N.

Until then, people didn’t really realize how much of the STEM crisis was a mythology that was perpetuated by employers and the academic community and was foisted on the IEEE community,” he said.</p><p>Charette made a career of questioning assumptions. The best way to mitigate risk, he told me as our Friday chat drew to a close, is to be careful making assumptions in the first place. “My main risk maxim is assumptions made are risks accepted.”</p>]]></description><pubDate>Sat, 01 Aug 2026 12:00:01 +0000</pubDate><guid>https://spectrum.ieee.org/risk</guid><category>Software</category><category>Robert-n-charette</category><category>It</category><category>Risk-analysis</category><category>Systems-engineering</category><dc:creator>Harry Goldstein</dc:creator><media:content medium="image" type="image/jpeg" url="https://spectrum.ieee.org/media-library/a-greenish-yellow-waxwing-bird-sitting-on-a-twig-eating-a-berry.jpg?id=67541842&amp;width=980"></media:content></item><item><title>IEEE Publishing Ethics Team Upholds Research Integrity</title><link>https://spectrum.ieee.org/ieee-publishing-ethics-research-integrity</link><description><![CDATA[

The group also works to increase the organization’s visibility in the broader publishing ethics area and helps IEEE volunteers write new policies.</p><p>Here are some highlights of the team’s activities last year. </p><h2>New detection tools</h2><p>IEEE conducted a pilot program in 2024 to integrate tools from the <a href="https://stm-assoc.org/" rel="noopener noreferrer" target="_blank">International Association of Scientific, Technical, and Medical Publishers</a> (STM) <a href="https://stm-assoc.org/what-we-do/strategic-areas/research-integrity/integrity-hub/" rel="noopener noreferrer" target="_blank">Integrity Hub</a> into the peer-review workflow of <a href="https://ieeexplore.ieee.org/xpl/RecentIssue.jsp?punumber=6287639" rel="noopener noreferrer" target="_blank"><em><em>IEEE Access</em></em></a>. The multidisciplinary, fully gold-open-access journal publishes research results across all IEEE fields of interest.</p><p>STM created the hub so scholarly publishers could access a suite of integrated, commercial, third-party research integrity tools as well as those developed by <a href="https://stm-assoc.org/what-we-do/core-services/stm-solutions/" rel="noopener noreferrer" target="_blank">STM Solutions</a>. The tools help the publishing group avoid printing problematic content upon manuscript receipt, rather than reacting postpublication.</p><p>The new features include the <a href="https://stm-assoc.org/stm-integrity-hub-incorporates-clear-skies-papermill-alarm-screening-tool/" rel="noopener noreferrer" target="_blank">Clear Skies Papermill Alarm</a>, which helps identify potentially fraudulent manuscripts at submission. Another is an integration with the <a href="https://stm-assoc.org/integrity-hub-continues-to-gain-momentum-with-inclusion-of-pubpeer-database-in-screening-tool/" rel="noopener noreferrer" target="_blank">PubPeer database</a>, which allows users to check whether references in a manuscript have received previous PubPeer comments or have been retracted—both of which can indicate quality or integrity issues. The <a href="https://stm-assoc.org/stm-integrity-hub-launches-new-research-integrity-tool/" rel="noopener noreferrer" target="_blank">duplicate submissions detector</a> can determine whether the same manuscript has been submitted to multiple journals by different publishers, often a sign of academic “paper mill” activity.</p><p>Following the success of the pilot, IEEE began working last year to expand the services to all its periodicals. It is anticipated that all IEEE periodicals will be included in the Integrity Hub screening by the end of this year.</p><h2>Raising visibility</h2><p>The team participated in industry-wide initiatives with STM. It also renewed membership in groups including the <a href="https://publicationethics.org/" rel="noopener noreferrer" target="_blank">Committee on Publication Ethics</a>, and the team continued its work sponsoring and presenting at conferences.</p><p>At a panel presentation during the <a href="https://www.councilscienceeditors.org/annual-meeting-2025" rel="noopener noreferrer" target="_blank">Council of Science Editors annual meeting</a> last year, <a href="https://www.linkedin.com/in/sulicz/" rel="noopener noreferrer" target="_blank">Amanda Sulicz</a>, manager of IEEE Research Integrity, participated in the Research Integrity Investigation panel session<em><em>.</em></em> She also presented at the Standardization of Publishing Integrity Norms and Corrective Actions poster session during the <a href="https://customer.sspnet.org/SSP/ssp/AM25/Home.aspx?hkey=ea26b5cc-0f12-4dc2-9401-f3be2e8148bf" rel="noopener noreferrer" target="_blank">Society for Scholarly Publishing</a>’s annual meeting, held 28 to 30 May 2025.</p><p><a href="https://www.linkedin.com/in/luigi-longobardi-38390819/" rel="noopener noreferrer" target="_blank">Luigi Longobardi</a>, the IEEE Publishing Ethics and Conduct director, gave a presentation at the Communication and Collaboration With Institutions session during <a href="https://stm-assoc.org/events/stm-innovation-integrity-days-2025/" rel="noopener noreferrer" target="_blank">STM Innovation and Integrity Days</a>, which took place 9 and 10 December.</p><p>IEEE was a sponsor of the <a href="https://sites.northwestern.edu/ncri2025/" rel="noopener noreferrer" target="_blank">National Conference on Research Integrity</a>, held 20 to 22 May 2025, and the <a href="https://peerreviewcongress.org/" rel="noopener noreferrer" target="_blank">International Congress on Peer Review and Scientific Publication</a>, held 3 to 5 September.</p><h2>Ethics reports</h2><p>The team is responsible for tracking <a href="https://spectrum.ieee.org/proposed-ieee-code-of-ethics-revisions" target="_self">ethics-related</a> complaints for all IEEE publications, including articles published in periodicals and conference proceedings. When complaints regarding an article’s integrity are received, either via email at <a href="mailto:pub-ethics@ieee.org" rel="noopener noreferrer" target="_blank">pub-ethics@ieee.org</a> or the anonymous <a href="https://secure.ethicspoint.com/domain/media/en/gui/20410/index.html" rel="noopener noreferrer" target="_blank">ethics reporting line</a>, the team works with IEEE volunteers to open a case, investigate the complaint, and resolve the matter.</p><p>Last year 591 cases were opened, a 56 percent increase over 2024. Of the 591 reports, 317 were closed and 274 are still under investigation. Of the complaints, 88 percent were research-related, including issues with plagiarism, AI-generated text, and falsification of—or unauthorized use of—data. The other 12 percent involved alleged misconduct by editors, reviewers, and conference organizers.</p><p>The complexity of the reported cases has expanded. An increasing number of the complaints deal with more than one article or complicated situations such as editorial misconduct or peer-review manipulation.</p><h2>Conference publications</h2><p>For the second consecutive year, the team participated in the joint <a href="https://events.ieee.org/ieee-conferences-committee/rosters-charters/" rel="noopener noreferrer" target="_blank">IEEE Publication Services and Products Board/IEEE Conferences Committee’s ad hoc committee on conference publication quality</a>. The committee is tasked with analyzing and reviewing problematic conference papers and enhancing quality screening of articles prior to publication to detect integrity issues such as plagiarism and tortured phrases. The committee also updates educational modules on organizing and managing conferences.</p><p>As part of the review process, the committee focused on conference articles that contained tortured phrases, which are nonstandard English expressions that are imprecise or erroneous and give the impression of technical jargon.</p><p>Many of the articles reviewed by the ad hoc committee were identified by the <a href="https://arxiv.org/abs/2210.04895" rel="noopener noreferrer" target="_blank">Problematic Paper Screener</a>, a free online tool that uses application programming interfaces to screen papers published online for potentially problematic content, such as tortured phrases, machine-generated content (<a href="https://pdos.csail.mit.edu/archive/scigen/" rel="noopener noreferrer" target="_blank">SCIgen</a> or <a href="https://thatsmathematics.com/mathgen/" rel="noopener noreferrer" target="_blank">Mathgen</a>, for example), or references to retracted content.</p><p>The ad hoc committee was responsible for reviewing and recommending the retraction of more than 1,700 problematic conference articles last year. </p><h2>Case studies</h2><p>From the cases the team reviewed, IEEE learned valuable information to help update its publishing policies and best practices.</p><p>Here are examples of two anonymized cases reported to the team last year.</p><h3>Case Study 1</h3><br/><p><strong>Updated Policies</strong></p><p>Occasionally, a misconduct case is so complicated that it requires an update to the <a href="https://pspb.ieee.org/images/files/opsmanual.pdf" rel="noopener noreferrer" target="_blank">PSPB Operations Manual</a>.</p><p>In this particular case, Coauthor 1 reported to the Publishing Ethics Team that the work was reused in an IEEE publication without proper credit. The new work also listed two coauthors not part of the original document. Coauthor 1 also reported the case to their university’s research integrity officer (RIO) for additional investigation.</p><p>Initially, adjudicating the case proved challenging because under the PSPB policies at the time, the issue would have been classified as a multiple publication, which typically results only in a warning for the authors of the new work.</p><p>With the assistance of the RIO, it was determined that the methodological and theoretical portions of the paper were previously derived in the university’s lab; therefore, the contributions of the two new authors were not substantial enough to warrant authorship.</p><p>After deliberations by the IEEE Publishing Conduct Committee and eventually the IEEE Document Working Group, which is responsible for updates to the Operations Manual, <a href="https://www.ieee.org/publications/rights/Investigating-misconduct" rel="noopener noreferrer" target="_blank">IEEE PSPB Policy 8.2.4</a> was updated to clarify policies regarding the adjudication process for reuse of material and the proper crediting of coauthors when material has been reused.</p><h3></h3><br/><div class="horizontal-rule"></div><h3>Case Study 2</h3><br/><p><strong>Faked Reviewers</strong></p><p>Using the screening tools and data available to IEEE periodical editors, an editor in chief was alerted to suspicious reviewer activity. Specifically, two of the reviewers assigned to an article submitted the exact same review text.

Astronomers don’t know. But they’ve determined that this invisible material must be far more abundant than the stars and nebulas that they can see. They’ve surmised as much from observing the gravitational effects of all this perplexing dark stuff, launching a decades-long campaign to understand its nature.</p><p>I recently learned that it is possible to sense the presence of dark matter using a small radio telescope such as the Discovery Dish<a href="https://spectrum.ieee.org/software-defined-radio" target="_self"> covered in these pages</a> last year. The trick is to know what observations to collect and how to analyze them. I’ll sketch that out below, but first let me describe the homemade radio telescope I put together for this project.</p><p>It’s a pyramidal-horn antenna, not unlike <a href="https://www.radio-astronomy.org/pdf/70th%20AnniversaryDiscNeutralH_David%20Ewen.pdf" rel="noopener noreferrer" target="_blank">the horn antenna first used in 1951</a> to detect the 1,420.4-megahertz radio emissions from interstellar clouds of neutral hydrogen in space. These emissions hold the key to confirming the presence of dark matter because such clouds can be found all over the galaxy, and their motions reflect what’s happening in different parts of the Milky Way.</p><p>I used an <a href="https://hornantennacalculator.blogspot.com/p/calculator.html" rel="noopener noreferrer" target="_blank">online calculator</a> to help me design my antenna, adopting dimensions I knew I could achieve using a US $25 <a href="https://www.acehardware.com/departments/building-supplies/roofs-and-gutters/roof-flashings/5172184?x429=true&gclsrc=aw.ds&gad_source=1&gad_campaignid=20155429886&gclid=EAIaIQobChMIi8ai2aejlQMVF1tHAR0slhjnEAQYAiABEgL8_vD_BwE" rel="noopener noreferrer" target="_blank">10-by-2-foot roll of roof flashing</a> and an emptied one-gallon paint-thinner can. (Next time, I’ll just buy an empty F-style can.)</p><p class="shortcode-media shortcode-media-rebelmouse-image"> <img alt="The major components of the radio telescope." class="rm-shortcode" data-rm-shortcode-id="81560265bb5c209e498dc0245e2600a3" data-rm-shortcode-name="rebelmouse-image" id="8128e" loading="lazy" src="https://spectrum.ieee.org/media-library/the-major-components-of-the-radio-telescope.png?id=67528495&width=980"/> <small class="image-media media-caption" placeholder="Add Photo Caption...">The horn antenna is made from tape, an empty paint-thinner can, and a roll of metal roof flashing [bottom row]. Signals are picked up with a low-noise amplifier [top middle] and passed to a software-defined radio receiver [top left].</small><small class="image-media media-photo-credit" placeholder="Add Photo Credit...">James Provost</small></p><p>Construction of the antenna itself was similar to that of the <a href="https://spectrum.ieee.org/track-the-movement-of-the-milky-way-with-this-diy-radio-telescope" target="_self">slightly smaller horn antenna I described in these pages in 2019</a>. I made my new antenna bigger, though, because I needed better angular resolution, allowing me to scan smaller regions of the sky.</p><p>To pick up the emissions from interstellar hydrogen, I used Nooelec’s $45 <a href="https://www.amazon.com/Nooelec-SAWbird-H1-Applications-Frequency/dp/B07XPV9RX2" target="_blank">SAWBird+ H1</a>, a device that combines two low-noise amplifiers with a standing-acoustic-wave filter centered on 1,420 MHz, in combination with a <a href="https://www.amazon.com/SDR-V4-RTL2832U-Software-Defined-Receiver/dp/B0GWVMVZ7R" target="_blank">RTL-SDR V4 dongle</a>. So it’s not too hard to put together the hardware needed to measure signals from hydrogen clouds. But how do you pull the signature of dark matter out of those signals?</p><p>The answer is that you use such measurements to gauge the speed at which clouds located at different distances from the center of the Milky Way are moving in their orbits.</p><p class="pull-quote"><span>You just have to show that the speed at which material orbits the center of the galaxy doesn’t fall off with distance.</span></p><p>You might think that these clouds circle around the galactic center in the same way that planets orbit the sun or satellites orbit the Earth, with objects close in orbiting faster than those farther out. Mercury, for example, zips around the sun at 47.4 kilometers per second, whereas Neptune lumbers along at a leisurely 5.4 km/s.</p><p>The Milky Way contains a central bulge of stars surrounding a supermassive black hole. So at first blush, the mass of the galaxy appears to be concentrated near its center. If that were the case, stars and clouds of other material would orbit more slowly as their distance from the center increases. If, however, there were enormous amounts of invisible matter present throughout the galaxy, you wouldn’t expect orbital velocities to diminish in this way.</p><h2>How Do You Measure the Speed of Interstellar Clouds?</h2><p>So to detect dark matter, you just have to show that the speed at which material orbits the center of the galaxy doesn’t fall off with distance. And radio observations are the easiest way to do that, because you can gauge speeds by measuring how much the signal from hydrogen clouds is shifted by the Doppler effect.</p><p>By pointing your radio telescope at different parts of the sky, you pick up emissions from clouds located at various distances from the galactic center. The frequency offset of these emissions from 1,420 MHz reflects the speed of approach or recession of those clouds relative to Earth.</p><p>You need measurements from the plane of the galaxy, at galactic longitudes between 0 and 90 degrees (a galactic longitude of 0 degrees points directly toward the center of the galaxy and 180 degrees directly away from it). Applying some high school trigonometry lets you convert these figures into orbital speeds around the galactic center, a technique known as the <a href="https://physicsopenlab.org/2020/09/08/measurement-of-the-milky-way-rotation/" target="_blank">tangent-point method</a>.</p><p class="shortcode-media shortcode-media-rebelmouse-image"> <img alt="A diagram showing the geometrical arrangement of an observation of a cloud close to the center of the galaxy, and a chart showing a relatively flat black trace with red circles corresponding to distance far from the center lying on the trace.

The bottom graph shows the astronomical community’s measurements for velocities around the galactic center [in black], with the author’s results plotted in filled and open red circles.</small><small class="image-media media-photo-credit" placeholder="Add Photo Credit...">James Provost</small></p><p>Experiments aiming my horn antenna at an <a href="https://www.inmarsat.com/" target="_blank">Inmarsat</a> geostationary satellite revealed that the angular resolution of my little radio telescope is about 20 degrees. So with the help of the planetarium program <a href="https://stellarium.org/" target="_blank">Stellarium</a>, I pointed my antenna in the plane of the galaxy at galactic longitudes of about 15, 30, 45, 60, 75, and 90 degrees, spacing things out in an effort to make each set of measurements largely independent.</p><p>I used the <a href="https://airspy.com/download/" target="_blank">SDR#</a> software with a plug-in called <a href="https://www.astronomy.me.uk/latest-version-of-if-average-plug-in-for-sdr-sharp-software" target="_blank">IF Average</a> to read the raw measurements coming in from the antenna. This plug-in stacks up data received over a few minutes, allowing a weak signal to build up and produce a clean radio spectrum that shows the 1,420-MHz line. In reality, it looks more like a bump, or even a set of bumps due to Doppler shifted emissions from multiple clouds, located at different distances from the galactic center. Fortunately, you only have to care about the cloud that’s receding the fastest—the one with the largest <a href="https://en.wikipedia.org/wiki/Redshift" target="_blank">redshift</a>, in astronomer-speak.</p><p>I used Microsoft Excel to analyze the shapes of radio spectra I gathered, modeling them as the sums of individual bell-shaped contributions from different clouds. That allowed me to estimate the largest redshift for each galactic longitude I probed. Then, again using Excel, I applied formulas that transformed those six redshift values into six pairs of orbital velocities and distances from the galactic center.</p><p>The plot of my results matched reasonably <span>well with a recent paper, “<a href="https://www.ioa.s.u-tokyo.ac.jp/~sofue/papers/sofcomp/2025-pasj-Inner-Rot-Curve-MilkyWay.pdf" target="_blank">The</a> </span><span><a href="https://www.ioa.s.u-tokyo.ac.jp/~sofue/papers/sofcomp/2025-pasj-Inner-Rot-Curve-MilkyWay.pdf">Inner Rotation Curve of the Milky Way</a>,” </span><span>in </span><em>Publications of the Astronomical Socie</em><em>ty of Japan</em><span>.</span><span> Two innermost points did show anomalously low orbital velocities. Another shot at curve fitting in Excel brought these results closer to expectations, but they were still somewhat off.</span></p><p>In any case, the orbital velocities I estimated did not diminish with distance from the galactic center—quite the opposite. <em><em>Something</em></em> out there is putting its stamp on how the Milky Way turns. And that basic observation is what allows me to say that, with the help of some roof flashing and a paint-thinner can, I’ve been able to detect dark matter from my backyard.</p>]]></description><pubDate>Thu, 30 Jul 2026 14:00:03 +0000</pubDate><guid>https://spectrum.ieee.org/dark-matter</guid><category>Typedepartments</category><category>Astronomy</category><category>Radio-astronomy</category><category>Radio-telescope</category><category>Dark-matter</category><dc:creator>David Schneider</dc:creator><media:content medium="image" type="image/png" url="https://spectrum.ieee.org/media-library/an-inverted-pyramidal-antenna-sits-atop-a-metal-box-with-a-feed-running-to-a-nearby-laptop.png?id=67528383&amp;width=980"></media:content></item><item><title>A Remote Indigenous Community Built One of Canada’s Fastest Fiber Networks</title><link>https://spectrum.ieee.org/indigenous-fiber-network</link><description><![CDATA[

Before the network, the rescue squad relied on a few handheld radios to pass information along.

For the people of Fort Albany First Nation, accessing many vital supplies and services means traveling about 500 km to the regional city of Timmins. By land, the trip is possible for only a few weeks each winter, when the swampy tundra freezes hard enough to construct a temporary road. “The southern way of doing things is very different than how we here in remote areas piece things together,” says Nakogee.</p><p>Telecommunications giants long saw little profit in serving the subarctic coast of James Bay. But even as satellite internet started to become available in remote communities, WJBTN staff saw the value in building and owning its own hard-wired internet service instead of relying on outside companies. Today, the nonprofit operates one of the fastest networks in Canada, while keeping both infrastructure ownership and revenue within the First Nations communities it serves.</p><p>WJBTN is part of a broader movement among Indigenous and remote communities <a href="https://firstmile.ca/about/" target="_blank">seeking more control</a> over their telecommunications infrastructure. In the United States, <a href="https://communitynetworks.org/content/tribal-broadband-networks" target="_blank">30 tribes</a> now operate fiber-to-the-home networks, many launched during COVID. Canada has since created a dedicated <a href="https://www.canada.ca/en/radio-television-telecommunications/news/2026/03/backgrounder-crtc-making-it-easier-to-connect-indigenous-communities-to-high-speed-internet-and-cellphone-services.html" target="_blank">Indigenous broadband</a> funding stream. And as more communities <a href="https://tribalbroadbandbootcamp.org/" target="_blank">pursue the expertise</a> and funding to build their own networks, WJBTN’s experience offers a blueprint for what locally owned connectivity can look like in some of the hardest places to serve.</p><h2>How a Power Line Became a Broadband Backbone</h2><p>While many towns in North America were connecting to optical fiber in the early 2000s, the subarctic communities were left out.</p><p>The residents of Fort Albany saw the earliest sign of improvement in 2008. That’s when their locally owned power company, <a href="https://fivenations.ca/" target="_blank">Five Nations Energy Inc.</a> (FNEI), strung fiber-optic cable on the utility poles that were delivering electricity from the dusty railway town of <a href="https://en.wikipedia.org/wiki/Moosonee" target="_blank">Moosonee</a>, 135 km away across the peat bogs. On the shore of the Moose River, Moosonee is the last stop for Ontario’s telecommunications providers. Its only link to the province’s highways is a 5-hour train ride that shuttles passengers, freight, and vehicles through the Boreal forest.</p><p class="shortcode-media shortcode-media-rebelmouse-image rm-float-left rm-resized-container rm-resized-container-25" data-rm-resized-container="25%" style="float: left;"> <img alt="Person in gray cap and maroon hoodie looking thoughtfully to the side" class="rm-shortcode" data-rm-shortcode-id="4bda963cfb2cceedb3827bb3f6a37fac" data-rm-shortcode-name="rebelmouse-image" id="264ca" loading="lazy" src="https://spectrum.ieee.org/media-library/person-in-gray-cap-and-maroon-hoodie-looking-thoughtfully-to-the-side.jpg?id=67101714&width=980"/></p><p class="shortcode-media shortcode-media-rebelmouse-image rm-float-left rm-resized-container rm-resized-container-25" data-rm-resized-container="25%" style="float: left;"> <img alt="A photo that shows the screen of a cellphone displaying the words \u201cFort Albany Search & Rescue.\u201d  " class="rm-shortcode" data-rm-shortcode-id="2e219d32f60f9bca3aa4e7f36bfb5fb9" data-rm-shortcode-name="rebelmouse-image" id="f84cc" loading="lazy" src="https://spectrum.ieee.org/media-library/a-photo-that-shows-the-screen-of-a-cellphone-displaying-the-words-u201cfort-albany-search-rescue-u201d.jpg?id=67101713&width=980"/> <small class="image-media media-caption" placeholder="Add Photo Caption...">Elizabeth Kataquapit [top], former chief of Fort Albany First Nation, says high-speed internet has transformed her community. Search & Rescue volunteers now coordinate emergency responses through a Facebook group [bottom]. </small><small class="image-media media-photo-credit" placeholder="Add Photo Credit...">Gavin John </small></p><p>Soon after, regional Cree leaders formed WJBTN to provide high-speed telecommunications in Moosonee and the three Indigenous communities to the north. WJBTN would lease the fiber-optic backbone from the power company, with just 1 gigabit per second of total capacity for the entire population of about 6,000 people.</p><p>But the new fiber backbone did not mean fast internet for residents. One of WJBTN’s first commercial clients was a telecom company called <a href="https://www.xittel.net/en/residential.aspx" target="_blank">Xittel</a>, which used microwave links and local access points to beam wireless internet to homes across each town. It wasn’t what subscribers were hoping for. This system frustrated users with delays, glitches, and strict data caps. Kataquapit calls it a “turtle.”</p><p>Everybody complained about the wireless. Xittel advertised a 10 megabit-per-second connection, but speed tests consistently showed 3 Mb/s for both uploads and downloads. And customers paid dearly if they ever exceeded their data limit. “You were billed close to CA $7 per megabit,” Nakogee recalls.</p><p>WJBTN’s dream had always been to connect everyone’s home to fiber optic and make it affordable. Without a technical team, roads, or any major funding, the company just had to figure out how.</p><h2>Designing a Fiber Network for the James Bay Coast</h2><p>When Nakogee joined WJBTN in 2014, the telecom company was still in its infancy. It was “a department huddled in the corner, trying to latch onto the services of FNEI,” he says.</p><p>Nakogee was asked to prepare a proposal to deliver 40 Mb/s fiber connections to each of the roughly 1,000 homes and businesses spread across 300 km of the James Bay coast. Back then, WJBTN operated on revenue from its early commercial and institutional customers—including Xittel, local government offices, hospitals, air navigation facilities, and family service centers that were connected to the first few strands of fiber. To make a residential fiber network possible, WJBTN first had to build both revenue and trust within the communities it hoped to serve; it had to convince people that the small new organization would follow through on its plan.</p><p class="shortcode-media shortcode-media-rebelmouse-image"> <img alt="A photo shows a man holding a laptop and sitting in an office in front of a large computer monitor.

Through years of diplomacy, the budget grew enough to support a business proposal for a fiber-to-the-home network. Together with engineer Dirk MacLeod, in 2015 Nakogee began hashing out the details of a bare-bones version of the system. The plan required both upgrading the network’s long-distance fiber backbone—<a href="https://www.ceragon.com/what-is-backhaul" target="_blank">known in telecom as the backhaul</a>—while also building the local infrastructure that would connect individual homes to the internet.</p><p class="shortcode-media shortcode-media-rebelmouse-image"> <img alt="A man in an office points to something on a large piece of paper spread before him.

Using equipment from telecom supplier <a href="https://www.nokia.com/optical-networks/" target="_blank">Infinera</a>, the new backhaul would deliver 100 Gb/s to distribution points in each town, with redundancy in case a fiber line failed.</p><p>Next came the challenge of connecting individual homes. Rather than extend a direct line from the central office for every customer, the engineers designed the network around a telecom architecture called <a href="https://www.gpon.com/" target="_blank">GPON (Gigabit Passive Optical Network)</a>, which reduced the fiber needed to connect each customer to the network. Fiber from the backbone would run to networking equipment at each town’s electrical substation, where passive optical splitters would distribute the connection among many households without requiring powered equipment at every junction. In remote communities where maintenance and repair are difficult, reducing the amount of active infrastructure was a necessity.</p><p>The total estimated cost was <a href="https://www.northernontariobusiness.com/press-release/fibre-to-the-home-service-launched-in-fort-albany-first-nation-5392514" target="_blank">CA $4.7 million</a>, or CA $4,700 per household.

Fort Albany mental health counselor Thomas Scott says he “couldn’t wait.” People seeking guidance for addiction or grief typically called him on landlines, and it was hard to help them over the phone without seeing their faces. Businesses, too, rejoiced—including the Kataquapit family store, which relied on the phone system for transactions.</p><h2>Testing and Deploying a Remote Fiber Network</h2><p>Winning approval for the project was one thing; building it across hundreds of kilometers of remote subarctic terrain was another.</p><p>Dirk MacLeod started with a schematic documenting the GPS position of every house, pole, and length of cable that would ultimately form the network. When WJBTN hired Montreal-based <a href="https://www.fonex.com/" target="_blank">Fonex Data Systems</a> to upgrade the backhaul, the detailed plan made it easy for contractor Tasso Varvarikos to design the deployment. Still, tuning the optical system to operate reliably across transmission lines stretching hundreds of kilometers required extra care. “Once you go up north, there’s no fiber store,” he says,</p><p>To minimize surprises in the field, Varvarikos traveled to telecom supplier Infinera’s laboratory in Stockholm, where he and other engineers assembled and tested the network before shipping it to the installation site. The Stockholm lab gave the team access to testing tools and technical specialists who helped configure the system before deployment in the remote fly-in communities. Using Infinera’s simulation software, Varvarikos says he and his colleagues “kicked the crap out of it in the lab” until the network performed reliably.</p><p class="shortcode-media shortcode-media-rebelmouse-image"> <img alt="A map of northern Ontario shows the location of Moosonee, Fort Albany, Kashechewan, and Attawapiskat along the western shore of James Bay.

First, more than two pallets’ worth of Infinera equipment were squeezed onto two charter aircraft in Timmins. Bush pilots, unfazed by the stringent logistics, made sure that one box reached Moosonee; the other one, Attawapiskat. Varvarikos says they packed extra fiber-optic transceivers, <a href="https://en.wikipedia.org/wiki/Patch_cable" target="_blank">patch cables</a>, tools, and “the kitchen sink and then an extra sink just in case.” By May, the team was ready to install the new backhaul—a months-long process that necessarily preceded household connections. Once the equipment was in place, the engineers tested the network to make sure the systems in each community could communicate reliably and that data moved correctly across the backbone.</p><p>During the switchover to the new system, the MacLeod brothers worked from substations in different communities along the coast while Varvarikos coordinated from Fort Albany. Communicating over a spotty phone line, they started moving connections from the old network to the upgraded backhaul, carefully reconnecting cables and verifying that traffic still flowed correctly between communities. Within days, the anchor customers—including hospitals, schools, and air-navigation systems—were hardwired to a 100-Gb/s backbone.</p><p>However, households were still relying on the slow legacy network. WJBTN’s next step was flying huge reels of fiber-optic cable into the remote communities at enormous cost. Nakogee recalls cutting predetermined lengths of cable, then repackaging it onto spools to load onto cargo aircraft. The backbone was finally in place; now WJBTN had to bring fiber to every home.</p><h2>Training a Local Fiber Crew</h2><p>Then, in a turn of events that rocked the communities, lead engineer Dirk MacLeod had a heart attack and died in July 2019. “My chest was ripped open,” Nakogee says. The grieving company shut down for the summer.</p><p>WJBTN had intended to spend three summers training local crews from each community’s power company to maintain and manage the network. After MacLeod’s death, one line worker quietly took it upon himself to finish extending fiber to distribution points in Fort Albany. The team made a plan to begin connecting homes the following spring.</p><p class="shortcode-media shortcode-media-rebelmouse-image"> <img alt="A photo shows the streets of a town with utility poles carrying many wires.

People were screaming for better internet, he recalls, but they wouldn’t let outsiders in. So instead of training local crews and building each town’s network simultaneously as planned, WJBTN made a tantalizing offer: The first community to allow MacLeod in would have its fiber-to-the-home network completed first. Fort Albany jumped on it.</p><p>Peyton Reuben, a recent computer systems graduate in Fort Albany, was seeking a new job when his cousin mentioned that there was a “fiber guy” in town.

Nonetheless, he started work the day he met MacLeod and got a crash course in building an <a href="https://www.ppc-online.com/blog/key-factors-to-consider-with-aerial-fiber-deployments" target="_blank">aerial fiber network</a>, running cables from utility poles into neighborhood connection boxes that ultimately served individual homes. The fun part was reaching every pole in every neighborhood in a town crisscrossed by tributaries of the Albany River. “We didn’t have a bucket truck, so we had to climb up the poles,” says Reuben. “It was quite the experience, going through thick brush and thigh-deep water.”</p><p>The hard part was splicing the fiber—fusing together hair-thin glass strands that connected homes to the larger network. Inside each connection box, distribution fibers had to be joined to cables leading to individual houses, one strand at a time—around 150 in each box. Reuben’s first attempt “looked like a plate of spaghetti,” says MacLeod. More splicing waited back at the substation, where optical splitters connected neighborhood lines to the town’s central GPON equipment. “It took me four times as long as Andrew to complete a splice tray back then,” says Reuben.</p><p class="shortcode-media shortcode-media-rebelmouse-image"> <img alt="A photo shows a bucket truck with a man in the bucket approaching the top of a utility pole.

By springtime, aerial cables linked every house—and future building sites—to the substation. Reuben calls it “a spider web that goes everywhere across town.”</p><p>Without much fanfare, on a night in April 2022, WJBTN <a href="https://www.northernontariobusiness.com/press-release/fibre-to-the-home-service-launched-in-fort-albany-first-nation-5392514" target="_blank">flipped the switch in Fort Albany</a>. The next morning, Kataquapit woke up to a different world. With 250 Mb/s download and 30 Mb/s upload speeds, she found herself just a click away from her children in faraway cities.</p><h2>Why Not Starlink?</h2><p>MacLeod and Reuben continued working up the coast, splicing cables and adding connection boxes. As COVID eased, they hired more local help, and the power company lent a hand with bucket trucks. “We were working 12 hours a day, 7 days a week,” says MacLeod. “Guys were sitting in the heat, in bucket trucks, learning on the fly how to do splicing.” By late 2022, the network reached every home.</p><p class="shortcode-media shortcode-media-rebelmouse-image rm-float-left rm-resized-container rm-resized-container-25" data-rm-resized-container="25%" style="float: left;"> <img alt="Hand adjusting fiber-optic cables in a labeled network equipment panel" class="rm-shortcode" data-rm-shortcode-id="bc6869baf62c2f0fbc1fd0d068d9fd86" data-rm-shortcode-name="rebelmouse-image" id="4d079" loading="lazy" src="https://spectrum.ieee.org/media-library/hand-adjusting-fiber-optic-cables-in-a-labeled-network-equipment-panel.jpg?id=67102064&width=980"/></p><p class="shortcode-media shortcode-media-rebelmouse-image rm-float-left rm-resized-container rm-resized-container-25" data-rm-resized-container="25%" style="float: left;"> <img alt="Network server rack with labeled fiber optic cables and glowing status LEDs" class="rm-shortcode" data-rm-shortcode-id="af5ddba498dd226b1492f0b9bfba6ed2" data-rm-shortcode-name="rebelmouse-image" id="4f928" loading="lazy" src="https://spectrum.ieee.org/media-library/network-server-rack-with-labeled-fiber-optic-cables-and-glowing-status-leds.jpg?id=67102061&width=980"/></p><p class="shortcode-media shortcode-media-rebelmouse-image rm-float-left rm-resized-container rm-resized-container-25" data-rm-resized-container="25%" style="float: left;"> <img alt="Weathered wooden cable reels with exposed black wire, yellow wall and person in background" class="rm-shortcode" data-rm-shortcode-id="54b6fded93ea343559c95bab634de409" data-rm-shortcode-name="rebelmouse-image" id="a203f" loading="lazy" src="https://spectrum.ieee.org/media-library/weathered-wooden-cable-reels-with-exposed-black-wire-yellow-wall-and-person-in-background.jpg?id=67102053&width=980"/> <small class="image-media media-caption" placeholder="Add Photo Caption...">Fiber-optic cables and networking equipment inside the Fort Albany substation distribute internet service throughout the community [top, middle]. Large spools of fiber-optic cable were flown in to connect homes [bottom]. </small><small class="image-media media-photo-credit" placeholder="Add Photo Credit...">Gavin John</small></p><p>Around that time, <a href="https://spectrum.ieee.org/tag/starlink" target="_blank">Starlink</a>’s satellite internet service was becoming widely available. Many of WJBTN’s potential clients asked why they shouldn’t just purchase that instead of a fiber-optic connection that involved drilling into their homes. But speed tests comparing Xittel, Starlink, and the new WJBTN connections showed a major difference in latency: In applications like video calls, Xittel and Starlink’s round-trip signal delays became painfully obvious. Unlike satellite systems, fiber networks don’t need to send signals hundreds of kilometers into orbit and back. That gave WJBTN a significant performance advantage.</p><p>MacLeod recalls a conversation with one line worker who wanted to turn to Starlink. “We told him our latency is so much better,” MacLeod says, explaining that ISPs measure performance by both bandwidth and latency. From Attawapiskat, a data packet traveling over WJBTN’s fiber network reached Toronto in 20 milliseconds. Comparable satellite connections took <a href="https://www.satelliteinternet.com/resources/what-is-internet-latency/" target="_blank">closer to 60 milliseconds</a>. And Xittel’s latency was much worse, at several hundred milliseconds. (Since then, WJBTN has reduced latency further, to about 12 milliseconds.)</p><p>The team’s success has bolstered other Indigenous broadband companies. WJBTN representatives have shared their experiences at <a href="https://indigenousconnectivity.org/indigenous-connectivity-summit/" target="_blank">Indigenous Connectivity Summits</a> since 2017, and how-to workshops have sprung up <a href="https://indigenousconnectivity.org/icw/" target="_blank">across Canada</a> (and <a href="https://tribalbroadbandbootcamp.org/" target="_blank">the United States</a>). And Canada has since created a dedicated broadband funding stream for Indigenous communities. Within Fonex Data Systems, the company hired to do the backbone work, the WJBTN implementation is now considered the model for a successful installation in a remote location.</p><p>Nakogee says ownership remains the key advantage. Unlike earlier telecom providers that leased infrastructure or delivered service wirelessly, WJBTN owns the backbone fiber, the right-of-way, and the poles carrying the network. That makes it far harder for outside telecom companies to displace the service. “That’s our secret weapon,” he says.</p><p>Fundamentally, it’s about sovereignty. By controlling the infrastructure that carries internet traffic, the communities can govern and maintain the network according to their own priorities rather than the financial goals of distant providers.</p><h2>How Fiber Changed Daily Life</h2><p>Shortly after the fiber network was installed, <a href="https://www.timminstoday.com/local-news/fort-albany-elects-first-woman-chief-5901868" target="_blank">Elizabeth Kataquapit became chief</a> of Fort Albany First Nation. During her term as chief, she kicked the community’s digital era into full gear, encouraging individuals who couldn’t attend community meetings in person to join over Zoom.</p><p>Counselor Scott now conducts grief and addiction sessions both in person and via video calls and can connect immediately in a crisis even if he’s away. And as a search-and-rescue volunteer, he responded to the Facebook message when the young man got lost in a winter snowstorm on James Bay. “If we were a half hour later, the person would have [been] gone,” says Scott.</p><p>Broadband has also changed everyday life in quieter ways. Residents run small businesses from their homes. Telehealth links patients to specialists in southern cities. More people are working remotely and taking classes online. “Quality of life is so much better,” Reuben says.</p><p>But the network has also brought to these northern communities the more isolating side of fast internet. Community members stream more movies and play more video games, and they meet face-to-face less frequently. Standing beside an enormous canoe in his front yard, Scott explains that while he’s grateful for Fort Albany’s new connection to the outside world, he’s equally intent on preserving close connections within the community. Today, he says, as he starts loading fishing nets into the canoe, “I’m taking the kids out after school to harvest whitefish.” <span class="ieee-end-mark"></span></p><p><em>This article appears in the August 2026 print issue as “Wiring the North.”</em></p>]]></description><pubDate>Thu, 30 Jul 2026 13:00:01 +0000</pubDate><guid>https://spectrum.ieee.org/indigenous-fiber-network</guid><category>Canada</category><category>Bandwidth</category><category>Starlink</category><category>Fiber-optics</category><category>Connectivity</category><dc:creator>Rachel Berkowitz</dc:creator><media:content medium="image" type="image/jpeg" url="https://spectrum.ieee.org/media-library/an-aerial-photo-shows-utility-lines-stretching-across-a-river.jpg?id=67106655&amp;width=980"></media:content></item><item><title>Negotiating Your Salary Is About More Than Money</title><link>https://spectrum.ieee.org/how-to-negotiate-your-salary</link><description><![CDATA[

Take the offer.”</span><br/></p><p>I could not disagree more.</p><p>Negotiating your offer is not ungrateful, and it isn’t greedy. Done well, it’s good for you and good for the company hiring you. I misunderstood this early in my career, and it cost me.</p><h2>I didn’t know it was an option</h2><p>When I got my first job in tech, I didn’t know negotiation was even on the table. The recruiter asked what salary I wanted, and I gave a number below the bottom of their range. They came back with the lowest number in their band—still more than I had asked for—and I was thrilled. I had no idea I’d left money on a table I couldn’t see.</p><p>Then I started teaching at a Bay Area coding bootcamp in the evenings. A coworker mentioned what he made and it was nearly double my salary for roughly the same work. My jaw dropped. </p><p>During that time, I began interviewing and got an offer. I handed in my resignation and my manager countered with an offer for nearly 30K more. That money had been there the whole time. At that moment, I realized my salary was a business decision, not a measure of my worth.</p><h2>What it looks like from the other side</h2><p>Years later, I became an engineering manager and saw the salary discussion from a different angle: A position would open. Many interviews later, we’d find someone we wanted, and HR would hand me a salary range to make an offer. I was encouraged to make an initial offer near the bottom to leave room for, you guessed it, negotiations.</p><p>Most applicants didn’t negotiate.</p><p>The first offer is rarely the ceiling. It’s usually the floor. Companies extend a reasonable number and quietly hope you say yes.</p><h2>It’s not all about the money</h2><p>Negotiating isn’t only about a bigger paycheck. (But who doesn’t want that?) </p><p>Let’s say you’re on the job market, maybe recently laid off, and a low offer comes in. You take it out of relief. Then you start, you like the team, and you quietly resent the number. Now you’re stuck with it, and you’ll probably leave that role inside a year or whenever the market improves.</p><p>Nobody wins there. You’re back on the market starting over, and the company loses someone good and pays more to replace you, when a fair number up front would have cost far less. </p><p>Paying you fairly is cheaper than starting over.</p><h2>How to actually do it</h2><p>People overcomplicate this. Once I have an offer, I say some version of this:</p><p>“Thank you so much for the offer, and I’m genuinely excited to join the team. I’m hoping we can come in around [10 to 20 percent higher than the original number]. Is there any wiggle room here?”</p><p>Then I stop talking and let them respond.</p><p>Why 10 to 20 percent and not double? The number you ask for is itself a signal. Ask for something wildly out of range and you’ve told them you never learned what the role pays, or that your expectations are miles from reality. That’s what makes a company walk away. A calibrated request reads as someone who knows their worth and did their homework.</p><p>You’ve probably heard a horror story about someone who asked for more and had the offer yanked. Any company that would pull an offer over a reasonable question about pay is telling you exactly how they’ll treat you once you’re inside.</p><p>If the salary can’t move, it isn’t the only lever. I’ve negotiated more remote days, a later start to drop my kids off, and a sign-on bonus when the base was locked. Most people negotiate none of these perks.</p><h2>You have more leverage than you think</h2><p>Negotiating can feel like something you can only do from a position of power. But if you’re in the final stages of an offer, you already have it. They want to hire you. They’ve spent weeks finding you. Now they’re hoping you say yes.</p><p>That’s true even if you were recently laid off. Even if it’s your first job. Even if the number already looks higher than you expected.</p><p>The game is being played whether or not you join in. Sit it out, and you’re not just leaving money on the table. You may be quietly shortening your own stay at a job you could have been happy in. So ask.</p><p><span>—Brian</span></p><h2><a href="https://spectrum.ieee.org/technical-interview-ai-arms-race" target="_self">The AI Arms Race in Technical Interviews Is Escalating </a></h2><p>If you’ve been on the job market for a software engineering role recently, you’ve probably encountered—or used—AI tools in the hiring process.

<img src="https://spectrum.ieee.org/media-library/smiling-woman-in-nccu-eagles-jersey-stands-with-arms-crossed-in-front-of-red-mural.png?id=67527627&width=1245&height=700&coordinates=0%2C62%2C0%2C63"/><br/><br/><p>Artificial intelligence is reshaping the skills employers expect from new graduates. In response, universities are scrambling to launch new courses, research centers, and industry partnerships that prepare students for today’s workforce. But building a cutting-edge AI curriculum demands funding and access to industry networks, resources that remain unevenly distributed across higher education. </p><p>At North Carolina Central University, <a href="https://www.nccu.edu/employee/sday" rel="noopener noreferrer" target="_blank">Siobahn Day Grady</a> is trying to change that equation.</p><p>In January 2025, Grady, an associate professor in the <a href="https://www.nccu.edu/slis" rel="noopener noreferrer" target="_blank">NCCU School of Library and Information Sciences</a>, launched the first AI research institute at a historically Black college or university, or HBCU. The <a href="https://www.nccu.edu/research/institutes-and-special-facilities/iaier" rel="noopener noreferrer" target="_blank">Institute for Artificial Intelligence and Emerging Research</a> (IAIER) aims in part to help students and faculty across the university develop the skills needed to navigate a labor market increasingly transformed by AI.</p><p>“There used to be a time where people could say, ‘I don’t do tech,’ or ‘That’s not for me,’” Grady says. “But we’re in a stage now where you do need digital skills. Now it’s evolving into AI literacy.” </p><p>The approach reflects a broader shift in how many universities are thinking about AI education. AI skills are no longer confined to computer science and engineering departments—and at NCCU, they can’t be. The university does not yet have a dedicated computer science program, though it is developing one alongside a new AI minor. </p><p>The challenge of providing these resources is especially acute for historically Black institutions. Although HBCUs account for roughly 3 percent of four-year institutions in the United States, they receive less than 1 percent of federal research and development funding, according to a <a href="https://tmcf.org/new-data-reveals-disproportionately-low-rd-funds-awarded-to-hbcus/" rel="noopener noreferrer" target="_blank">2025 report </a>by the Center for American Progress and the Thurgood Marshall College Fund. The same report found that 17 of the 43 federal agencies that distributed research funding to universities in 2023 awarded no funding to HBCUs. </p><p>Yet less than two years since its launch, IAIER has emerged as a powerhouse for interdisciplinary AI education. Backed by a US $1 million <a href="https://google.org" rel="noopener noreferrer" target="_blank">Google.org</a> grant, the institute has engaged more than 2,800 students, faculty members, and community residents through research initiatives and training. Now the challenge is sustaining that momentum to keep up with rising demand.</p><p>“We have a guiding principle that we lead with on our campus,” Grady says. “AI is for everyone.”</p><h2>Why one research group wasn’t enough</h2><p>The mission to expand AI literacy grew out of Grady’s lifelong curiosity about technology. “I was born during a time [when] the internet did not exist,” she says. “Ever since the internet came to be, it’s changed our entire world.” </p><p>Grady was particularly drawn to the questions tech raises about privacy, identity, and human behavior. After receiving her bachelor’s degree in computer science and master’s degrees in AI and information science, Grady pursued a Ph.D. in computer science at the <a href="https://www.ncat.edu/" rel="noopener noreferrer" target="_blank">North Carolina Agricultural and Technical State University</a> to dig into those questions. </p><p>Her <a href="https://www.proquest.com/openview/2d76e0ff1f4fadb5fe010f0d5fca858f/" rel="noopener noreferrer" target="_blank">dissertation</a> focused on authorship attribution in social media, using machine learning and natural-language processing to determine whether a person’s writing style could reveal their identity. “I’ve always been intrigued by how much data we give for free,” Grady says. That work introduced her to the power of AI systems to detect patterns hidden within large datasets. </p><p class="pull-quote"><span>“We have a guiding principle that we lead with on our campus: AI is for everyone.”</span></p><p>After completing her doctorate in 2018, Grady joined NCCU as an assistant professor in the School of Library and Information Sciences. There, she researched machine learning applications for health care and autonomous vehicles. In 2020, she launched the Laboratory for Artificial Intelligence and Emerging Research at NCCU, giving students opportunities to participate in hands-on projects and explore AI beyond the classroom.</p><p>Then in 2024, an opportunity emerged to apply for a Google grant, and Grady began thinking beyond a single research group. Rather than building another faculty lab, she envisioned an institute that could serve the entire university during the AI boom. “We wanted to capitalize on the moment and make sure we don’t get left behind,” Grady says. </p><p>Since receiving the $1 million grant, Grady and her team have built a university-wide AI initiative, launched new academic programs, organized conferences, secured external support, and created research opportunities.</p><p>“We’ve really operated like a startup,” Grady says. </p><h2>AI beyond computer science</h2><p>As part of the institute’s goal of integrating AI education across disciplines, all NCCU freshmen are <a href="https://www.nccu.edu/news/nccu-among-first-hbcus-require-ai-training-freshmen" target="_blank">required to complete an introductory AI course</a>, designed in partnership with <a href="https://skillsbuild.org/" target="_blank">IBM</a>, to build foundational prompting skills. The institute has also worked with faculty development teams to help instructors integrate AI into their teaching.</p><p>Research is another part of the strategy. IAIER has awarded seed grants of up to $10,000 to faculty members exploring AI applications across departments. <a href="https://www.nccu.edu/research/institutes-and-special-facilities/iaier/seed-grant-program/2025-2026-iaier-seed-grant-funding-awardees" rel="noopener noreferrer" target="_blank">The first cohort</a> funded 11 projects spanning social work, digital archiving, health care, and information science. One project, for instance, is creating an AI lab where students in social work courses can practice client interactions through simulations. </p><p>“It’s really interesting to see the lens that our researchers take in trying to solve complex problems and also bring our students along with them,” Grady says.</p><p>The institute’s growth has been fueled by a mix of workforce training, interdisciplinary research, and, especially important, industry engagement. “Industry is where the advancements are really moving at that very fast rate,” Grady says, “not necessarily higher ed.”</p><p>To bridge that gap, IAIER hosts events that connect students and faculty with researchers, employers, and technology leaders. It has held sessions with companies including Deloitte, FICO, and Anthropic. Partnerships with Google and IBM let students gain recognized certificates and credentials. And last year, the institute hosted the first <a href="https://academy.openai.com/public/events/the-iaier-at-nccu-x-openai-academy-summit-hbcus-leading-the-future-ijyucx0rve?agenda_day=68484fd45114dd90aa5aa378&agenda_track=68484fd55114dd90aa5aa38d&agenda_stage=68484fd45114dd90aa5aa37e&agenda_filter_view=stage&agenda_view=list" rel="noopener noreferrer" target="_blank">OpenAI Academy Summit</a> held at an HBCU, drawing 444 participants from more than 40 institutions. </p><h2>Sustaining the vision</h2><p>The institute’s rapid growth has created a new challenge: continuing its momentum.</p><p>“Funding right now is the biggest barrier for [IAIER] to remain sustainable,” Grady says. As interest in the institute continues to grow, demand for its programs is beginning to outpace its capacity. “People just want more,” she says.</p><p>The bottleneck reflects a broader tension across higher education. <a href="https://spectrum.ieee.org/state-of-ai-index-2026" target="_blank">AI is evolving quickly</a>, while developing new academic programs, training faculty, and building research capacity takes time. The uncertainty is compounded by a shifting political landscape. As a whole, U.S. universities are grappling with proposed <a href="https://spectrum.ieee.org/harvard-funding-cuts" target="_blank">cuts to federal research spending</a> and increased scrutiny of diversity-focused initiatives under the Trump administration. However, in September 2025, the administration also announced a $500 million one-time investment in HBCUs and higher-ed institutions chartered by Native American tribal governments. </p><p>Meanwhile, NCCU has continued to attract new investment. Last September, in a collaboration with Howard University and two other institutions, IAIER <a href="https://nsf.elsevierpure.com/en/projects/research-coordination-network-on-assessing-and-predicting-jobs-ou-2/" rel="noopener noreferrer" target="_blank">received a nearly $500,000 award</a> through a <a href="https://www.aijobsrcn.org/" rel="noopener noreferrer" target="_blank">National Science Foundation research coordination network program</a> to help define emerging AI jobs, identify in-demand skills, and inform future credentials and curricula. That work will continue this fall when IAIER opens its first dedicated physical space on campus, Grady says.</p><p>Over the next several years, Grady plans to expand academic programming, launch the university’s computer science major and its AI minor, increase faculty research opportunities, and integrate AI more deeply across campus operations. She also plans to deepen the institute’s collaborations with industry partners.</p><p>Beyond program expansion, Grady sees the institute’s long-term success as linked to building a model other universities can adapt. “We’re creating a framework that can help not only HBCUs,” she says, “but also help any university looking to do similar work.” </p>]]></description><pubDate>Wed, 29 Jul 2026 14:00:02 +0000</pubDate><guid>https://spectrum.ieee.org/siobahn-day-grady-ai-hbcu</guid><category>Artificial-intelligence</category><category>Typedepartments</category><category>Ai-research</category><category>Universities</category><category>Higher-education</category><dc:creator>Aaron Mok</dc:creator><media:content medium="image" type="image/png" url="https://spectrum.ieee.org/media-library/smiling-woman-in-nccu-eagles-jersey-stands-with-arms-crossed-in-front-of-red-mural.png?id=67527627&amp;width=980"></media:content></item><item><title>AI Is Hyper-Scaling Digital Inequality</title><link>https://spectrum.ieee.org/ai-digital-divide</link><description><![CDATA[

It helps write emails and software code, filters job applications, powers recommendation systems, and is increasingly being integrated into education, health care, finance, and public administration. Industry leaders talk about “AI for everyone,” while governments rush to publish national AI strategies and build sovereign compute.</p><p>Yet over the past decade, working on digital inclusion and digital literacy projects in regions from Europe to sub-Saharan Africa and Southeast Asia, <a href="https://link.springer.com/book/10.1007/978-3-031-30808-6" rel="noopener noreferrer" target="_blank">I’ve seen the same pattern repeat</a>: Each new wave of “transformative” technology lands on a landscape already stratified by connectivity, skills, and institutional capacity. The current AI wave is no exception. If anything, it amplifies those underlying fractures.</p><p>Still, some countries are exploring ways of participating in AI development without directly replicating the frontier-model race dominated by the United States and China. Recent developments in South Africa and Indonesia illustrate both the possibilities and challenges. The stakes extend far beyond access to AI. Countries that remain primarily consumers rather than creators of AI risk losing opportunities to build local innovation ecosystems, strengthen public-sector capacity, and ensure that their own languages, cultures, and societal priorities are reflected in AI systems. In this sense, the AI divide is also becoming a divide in economic opportunity and technological influence.</p><h2>AI compute is clustering in a few places</h2><p>Recent analyses from Stanford University’s 2026 <a href="https://hai.stanford.edu/ai-index/2026-ai-index-report" rel="noopener noreferrer" target="_blank">AI Index report</a> that the United States alone hosts more than 5,000 data centers, over 10 times as many as any other single country. Because AI workloads are increasingly performed on cloud platforms rather than local infrastructure, this concentration of compute also becomes a concentration of dependency. According to <a href="https://www.worldbank.org/en/publication/dptr2025-ai-foundations" rel="noopener noreferrer" target="_blank">World Bank data</a>, in 2023 the United States accounted for roughly 87 percent of global exports of cloud computing and data-storage services.</p><p>For most countries, this means that <a href="https://spectrum.ieee.org/europe-tech-sovereignty-package" target="_self">AI development is not just technologically but commercially and geopolitically outsourced</a> and out of their control. The result is an AI ecosystem where a small number of states and firms host the computational engines that power globally deployed systems.</p><p>Systems trained, standardized, and governed within a narrow set of institutional and linguistic environments may struggle to serve a genuinely global public.</p><h2>Skills and AI literacy are deeply stratified</h2><p>Even where connectivity and cloud access exist, not everyone is equally positioned to make use of them. Across the Organisation for Economic Co-operation and Development (OECD) countries, only around <a href="https://www.oecd.org/en/publications/bridging-the-ai-skills-gap_66d0702e-en.html" rel="noopener noreferrer" target="_blank">40 percent of adults possess more than basic digital problem-solving skills</a>, while advanced computational and AI-related competences remain concentrated among highly educated workers and technology-intensive sectors.</p><p>At the same time, governments are racing to integrate AI into education, often starting at higher levels of schooling. UNESCO <a href="https://www.unesco.org/ethics-ai/en/node/367" rel="noopener noreferrer" target="_blank">has reported</a> growing efforts worldwide to integrate AI into education, while support for AI literacy in primary and lower secondary education, as well as ethical training for educators, remains uneven. </p><p>Those with robust schooling, advanced digital skills, and stable connectivity are best positioned to treat AI as a tool to extend their capabilities. <a href="https://www.oecd.org/en/publications/how-do-people-experience-new-technologies-and-generative-ai_49b8d10e-en/full-report.html" rel="noopener noreferrer" target="_blank">Recent OECD survey data</a> show that participation in AI-related training remains strongly stratified by educational attainment: 36 percent of respondents with tertiary education reported undertaking AI-related training in the previous year, compared with just 18 percent of those with upper-secondary education. Those on the wrong side of the divide are more likely to experience AI as an opaque system acting upon them, from algorithmic welfare systems such as the <a href="https://www.theguardian.com/technology/2020/feb/05/welfare-surveillance-system-violates-human-rights-dutch-court-rules" rel="noopener noreferrer" target="_blank">Dutch childcare benefits scandal</a> to AI-assisted hiring tools such as <a href="https://www.reuters.com/article/world/amazon-scraps-secret-ai-recruiting-tool-that-showed-bias-against-women-idUSKCN1MK08G/" rel="noopener noreferrer" target="_blank">Amazon’s discontinued AI recruiting system</a>, rather than as a technology they can actively interrogate or shape.</p><h2>Investment and governance: Who gets a seat at the table?</h2><p>The core agenda-setting power often remains with a narrow set of industry actors and a small group of technologically advanced states. Most other countries remain in a perpetual catch-up posture, adapting imported models, standards, and templates for “trustworthy AI” to their own contexts, and may have limited local capacity to assess trade-offs or propose alternatives. </p><p>In countries such as Indonesia and South Africa, communities generate data at massive scale yet still have little voice in how AI systems are designed, governed, or deployed. Their <a href="https://spectrum.ieee.org/indigenous-ai-voice-models-maori" target="_self">languages are underrepresented in training data</a>; their institutions are under-resourced in regulatory forums; their experiences rarely feature in benchmark datasets. For many countries in the global South, participation in AI still occurs largely through adapting imported systems rather than shaping how those systems are designed, governed, or deployed. </p><p>In South Africa, the Department of Communications and Digital Technologies released a <a href="https://www.techpolicy.press/south-africa-has-ai-leverage-its-draft-policy-leaves-it-unused/" rel="noopener noreferrer" target="_blank">draft national AI policy</a> in April 2026, proposing new oversight institutions. The department withdrew the draft days later after a journalist discovered that at least six of its academic citations did not exist, apparently AI-generated hallucinations. The minister called it <a href="https://www.reuters.com/world/africa/south-africa-withdraws-ai-policy-due-fake-ai-generated-sources-2026-04-27/" rel="noopener noreferrer" target="_blank">“an unacceptable lapse.</a>“ The episode sharply illustrates the gap between AI governance ambition and the institutional capacity needed to implement it, though the new AI panel the country has since constituted has a chance to use <a href="https://spectrum.ieee.org/south-africa-ai-policy" target="_self">South Africa’s unique leverage</a>.</p><p>Indonesia presents a case of deliberate, if constrained, public-sector agency. The National Research and Innovation Agency (BRIN) which now leads AI implementation under the national strategy, has built <a href="https://restofworld.org/2024/indonesia-ai-tools-brin-government-agency/" rel="noopener noreferrer" target="_blank">practical AI tools aimed at underserved communities</a> rather than frontier capabilities, including an app that uses satellite data and machine learning to help artisanal fishermen locate schools of fish, multilingual language models trained on Indonesian and local languages such as Javanese and Sundanese, and <a href="https://www.lightreading.com/ai-machine-learning/indonesia-s-upgraded-sahabat-ai-features-a-multilingual-chat-service" rel="noopener noreferrer" target="_blank">AI chatbots deployed in government services.</a> In August 2025, the Ministry of Communication and Digital Affairs released <a href="https://govinsider.asia/intl-en/article/indonesia-unveils-national-ai-roadmap" rel="noopener noreferrer" target="_blank">a national AI road map</a> with a target of training 100,000 AI-skilled workers annually. </p><p>The choice is not simply between “AI superpower” and “passive recipient.” </p><p>Regional cooperation may also become increasingly important. In 2024 African ministers adopted a Continental AI Strategy and African Digital Compact. Participants in the April 2025 <a href="https://dsup.substack.com/p/dsfsi-at-the-global-ai-summit-on" rel="noopener noreferrer" target="_blank">Global AI Summit on Africa in Kigali</a> explored how regional coordination, <a href="https://www.news.uct.ac.za/news/audio/-article/2026-05-04-uct-researchers-develop-ai-model-for-11-south-african-languages" rel="noopener noreferrer" target="_blank">local-language AI models</a>, public universities, and <a href="https://scienceforafrica.foundation/media-center/open-research-proposals-adopted-east-africas-ai-declaration" rel="noopener noreferrer" target="_blank">open-source ecosystems</a> might <a href="https://carnegieendowment.org/posts/2025/09/understanding-africas-ai-governance-landscape-insights-from-policy-practice-and-dialogue" rel="noopener noreferrer" target="_blank">reduce long-term dependence on externally developed AI systems</a>.</p><h2>A different way to think about the AI divide</h2><p>None of this means that people should slow or abandon AI, nor that cloud concentration or venture capital are inherently bad. Instead, when we talk about an “AI revolution,” we should also ask who can shape it and who can merely adapt to it.</p><p>Digital-divide debates once focused on devices and connectivity, later expanding toward skills and outcomes. But the current AI wave adds another layer: disparities in who can meaningfully participate in deciding what AI is for, which problems it is meant to solve, and which social priorities it ultimately serves.</p><p>For engineers and policymakers, this raises difficult but necessary questions. Are they designing AI systems and infrastructures that broaden, rather than narrow, participation in shaping technological change? When governments roll out national AI strategies or integrate AI into public services, whose constraints, languages, and institutional realities are they including?</p><p>Many observers frame the current AI moment as <a href="https://spectrum.ieee.org/state-of-ai-index-2026" target="_self">a competition</a>. But technological competition is never only about speed. It is also about who can influence the direction of change.</p><p>AI is already spreading globally. The deeper question is whether the technologists and policymakers responsible for it will ensure that meaningful participation in shaping that future will spread as well.</p>]]></description><pubDate>Wed, 29 Jul 2026 11:00:04 +0000</pubDate><guid>https://spectrum.ieee.org/ai-digital-divide</guid><category>Artificial-intelligence</category><category>Digital-divide</category><category>Digital-literacy</category><category>Education</category><dc:creator>Danica Radovanović</dc:creator><media:content medium="image" type="image/jpeg" url="https://spectrum.ieee.org/media-library/a-painting-with-overlapping-concentric-shapes-in-blue-and-yellow.jpg?id=67163886&amp;width=980"></media:content></item><item><title>Laboratoria’s Mariana Costa Empowers Women in Tech</title><link>https://spectrum.ieee.org/mariana-costa-women-in-tech</link><description><![CDATA[

And for too long, women across the region have been locked out of them, she says.</p><p>Costa is president of <a href="https://laboratoria.la/en" rel="noopener noreferrer" target="_blank">Laboratoria</a>, a U.S.-registered nonprofit based in Miami that she helped found. Laboratoria has trained thousands of women in 11 Latin American countries for technology careers. She has built training centers in the countries and has placed graduates at major companies. Meanwhile, she has become one of the most recognized voices in the region on workforce equity and tech education for women.</p><p>IEEE recognized her work with its <a href="https://corporate-awards.ieee.org/recipient/mariana-costa/" rel="noopener noreferrer" target="_blank">President’s Award</a> this year for her “distinguished leadership and contributions to the betterment of society.” Recipients of the award are selected by the IEEE president with the consent of the IEEE Board of Directors.</p><p>Costa says the recognition came as a surprise because she is not an engineer by training and had never considered becoming affiliated with IEEE.</p><p>She was presented with the award at the <a href="https://spectrum.ieee.org/ieee-celebrates-honors-ceremony-2026" target="_self">IEEE Honors Ceremony</a> on 24 April in New York City.</p><h2>Peru: a country of contrasts</h2><p>Costa grew up in Lima, Peru’s capital, in a household with no connection to engineering or technology. Her mother was an art historian and professor, and her father was a lawyer. The family was financially comfortable and traveled abroad regularly. Costa attended well-resourced schools.</p><p>That economic stability came with a reckoning, Costa says, in that she recognized early on that economic inequality had created separate societies inside Peru. Her parents, she says, made it “clear that my reality wasn’t the reality of most people in my country.”</p><p>Lima is a microcosm of the country, she says. The divide in the capital city is visible: A kilometers-long concrete wall topped with barbed wire separates wealthier neighborhoods from shantytowns, where residents lack running water.</p><p>Nationally, there are splits along ethnic and geographic lines. The highland and jungle regions remain home to mostly indigenous communities with limited educational access and a deep cultural distance from the Hispanic-dominated coast.</p><p>The questions that stirred in her as a child never left, she says.</p><p>“Why do I live in a country where so much depends on where you’re born?” she asked herself. “What does it mean to be Peruvian when individual realities are strikingly different?”</p><p>Those questions followed her to the <a href="https://www.getsmarter.com/products/universities/the-london-school-of-economics-and-political-science?gclsrc=aw.ds&&&ef_id=c:524987838476_d:c_n:g_ti:kwd-296547014814_p:_k:london%20school%20of%20economics_m:e_a:126288917990&gad_source=1&gad_campaignid=13137345744&gbraid=0AAAAADmgJP19b7OXwoaGcfVpuFd-lIRKm&gclid=Cj0KCQjwxvjRBhC2ARIsAI7KJa1xYb8TIS-QU7rdGmN50DDgNyqnsm5Wl90XqKbKb6XQBMVqjSLys0kaApqeEALw_wcB" rel="noopener noreferrer" target="_blank">London School of Economics</a>, where she studied international relations, graduating with a bachelor’s degree in 2007. She held onto the questions when she moved to Washington, D.C., where she spent the next four years working for the <a href="https://www.oas.org/en/" rel="noopener noreferrer" target="_blank">Organization of American States</a>, helping Latin American governments improve public services that fall under the heading of civil registration.</p><p class="pull-quote">“I said, ‘How can it be? The tech space has so many rich opportunities. Why aren’t any women here?’”</p><p>The OAS <a href="https://www.oas.org/ext/en/democracy/PUICA" target="_blank">Universal Civil Identity Program in the Americas</a> provides technical support to national civil registry institutions, modernizing them to foster social inclusion and ensuring the right to civil identity for all people. Without civil identity, a person can’t access education, health care, legal employment, social services, or the right to vote. People without the classification don’t exist in the eyes of the government. They also can’t own property, get married officially, or pass citizenship rights to their children.</p><p>Doing that work deepened her concern about the socioeconomic disparities in her homeland, she says. In search of practical solutions to those problems, she went to New York City in 2011 to further her education. She earned a master’s degree in public administration and development from <a href="https://www.columbia.edu/" target="_blank">Columbia</a> in 2013.</p><p>Technology was not yet part of a solution. But Costa already had met someone who would change that.</p><h2>Falling in love with a programmer</h2><p>While working in Washington, Costa met <a href="https://www.wearefamilyfoundation.org/mentors-2020/herman-marin" target="_blank">Herman Marìn</a>, a software engineer who used digital tools in support of social causes. Because he was doing work she had never associated with programmers before, her assumptions about the field dissolved quickly.</p><p>“I had a vision of [programmers doing] something not very social—strictly technical,” she says. “And my then-boyfriend, now husband, actually worked for different social movements that used technology to address social causes.”</p><p>That realization cracked something open, she says: “I said, ‘Oh! Technology can actually be a tool to address some of the more stubborn problems in our societies.’”</p><p>After earning her degree at Columbia, Costa returned to Lima with her husband. She had been abroad for nearly a decade and felt the pull of home.</p><p>“The thought of not moving back to my country was something that tormented me a bit,” she says. “I really felt I had to move back, at least to try it out and contribute somehow.”</p><h2>What Latin America’s tech space lacked</h2><p>When Costa, her husband, and a friend from graduate school moved to Lima, they had modest savings and big ambitions. They wanted to build something that combined technology with social impact.</p><p>They started with what they had: a small digital services agency, where they built websites for clients.</p><p>The business grew, and they hired more employees. Their team expanded to a dozen software engineers. And as it did, Costa noticed three things.</p><p>First, there weren’t enough trained developers to meet the demand. Second, many of their best hires did not have traditional computer science degrees. Some had never even finished college.</p><p>“There was no other space where you could actually build an amazing career and get a well-paying job without a good degree from a good school,” she says. “The tech world was different. It was open in ways other fields weren’t.”</p><p>Thirdly, she noticed that there were no women on the team. In the first six months, Costa says, they didn’t interview a single female developer.</p><p>Her colleagues shrugged. It’s just how it is, they told her.</p><p>Costa, the outsider, didn’t accept that.</p><p>“I said, ‘How can that be? The tech space has so many rich opportunities,’” she says. “‘Why aren’t there any women?’”</p><h2>Building Laboratoria</h2><p>In 2014 she decided to launch Laboratoria. The business model was simple: Find talented women who hadn’t yet broken into tech, train them quickly on practical skills, and connect them with employers who needed developers.</p><p>Laboratoria started offering a six-month immersive boot camp that covered Web development, UX design, <a href="https://ieeexplore.ieee.org/document/10765410" target="_blank">data literacy</a>, strategic use of <a href="https://spectrum.ieee.org/topic/artificial-intelligence/" target="_self">artificial intelligence</a>, and soft-skills coaching such as interview prep and projecting confidence.</p><p>Just as important for career success, Costa says, is a <a href="https://spectrum.ieee.org/ai-in-mathematics" target="_self">user-centered mindset</a>. She says Laboratoria’s program emphasizes the discipline of keeping the client’s needs in mind when designing the work.</p><p>The teaching model has evolved beyond the boot-camp structure, but the organization still focuses on helping Latin American women develop tech skills and land quality jobs in the digital age. These days, the training, conducted via twice-weekly live <a href="https://www.zoom.com/" target="_blank">Zoom</a> sessions, lasts six weeks.</p><p>“We needed developers ourselves,” she says of the company’s original logic. “I said, ‘Why don’t we run a program to train women—women who are incredibly talented but haven’t been given a chance yet—and help them gain the skills they need to get a great job as quickly as possible?’”</p><p class="shortcode-media shortcode-media-rebelmouse-image rm-float-left rm-resized-container rm-resized-container-25" data-rm-resized-container="25%" rel="float: left;" style="float: left;"> <img alt="Three smiling adults pose together on a green sofa in a bright living room." class="rm-shortcode" data-rm-shortcode-id="93d5a0060abb2c81ccd29705eed2f253" data-rm-shortcode-name="rebelmouse-image" id="2b804" loading="lazy" src="https://spectrum.ieee.org/media-library/three-smiling-adults-pose-together-on-a-green-sofa-in-a-bright-living-room.jpg?id=67546536&width=980"/> <small class="image-media media-caption" placeholder="Add Photo Caption..." style="max-width: 100%;">Mariana Costa [seated, right] poses with Laboratoria co-founder and CEO Gabriela Rocha and co-founder and chief product officer Rodulfo Prieto.</small><small class="image-media media-photo-credit" placeholder="Add Photo Credit..." style="max-width: 100%;">Valeria Martens</small></p><p>It worked. Laboratoria expanded from Lima to Santiago, Chile; Mexico City; São Paulo, Brazil; and Bogotá, Colombia. The organization eventually incorporated as a nonprofit in the United States. Today its programs are held remotely in Latin America’s major job markets. So far, Laboratoria has opened the doors to tech careers for more than 3,500 women.</p><p>Costa says she believes the most important skills Laboratoria’s graduates need aren’t purely technical. Close behind the growth mindset is self-confidence, she says.</p><p>“Knowing who you are, valuing who you are, and learning to trust yourself and your capacities are indispensable traits,” she says.</p><p>Networking, she adds, is the third pillar, and often the hardest to build for women without access to elite schools or flexible work schedules.</p><p>“When you go out in the market,” she says, “you realize that having a network of people who trust you and know your work is such a valuable and critical asset.”</p><h2>IEEE: a new connection</h2><p>Costa’s introduction to IEEE came late—but it landed hard.</p><p>She is not an IEEE member, so when she was contacted this year about receiving the President’s Award, she did her homework on the organization. What she found, she says, was a public charity whose reach and values aligned with her mission.</p><p>“IEEE is about expanding access to opportunities in the world of technology,” she says. “And that’s also the core of what we do at Laboratoria.”</p><p>She says she also sees IEEE as a living example of something her company preaches every day: “I was talking about the value of professional networks, and I think IEEE is such an amazing reference in that space. It exemplifies this belief that human connection—not only doing your work but also sharing and learning with others—is at the core of building thriving technology careers.”</p><p>The engineering organization found her well after she launched her tech-related career. But it wasn’t too late. She says she intends to make the most of the connection.</p>]]></description><pubDate>Tue, 28 Jul 2026 18:00:01 +0000</pubDate><guid>https://spectrum.ieee.org/mariana-costa-women-in-tech</guid><category>Ieee-member-news</category><category>Women-in-technology</category><category>Diversity</category><category>Ieee-presidents-award</category><category>Careers</category><category>Type-ti</category><dc:creator>Willie D.

He pioneered the use of graphics processing units (GPUs) to train deep learning models in the late 2000s with his students at <a href="https://stanfordmlgroup.github.io/" rel="noopener noreferrer" target="_blank">Stanford University</a>, cofounded <a href="https://research.google/teams/brain/" rel="noopener noreferrer" target="_blank">Google Brain</a> in 2011, and then served for three years as chief scientist for <a href="https://ir.baidu.com/" rel="noopener noreferrer" target="_blank">Baidu</a>, where he helped build the Chinese tech giant’s AI group. So when he says he has identified the next big shift in artificial intelligence, people listen. And that’s what he told <em>IEEE Spectrum</em> in an exclusive Q&A.</p><hr/><p>
	Ng’s current efforts are focused on his company 
	<a href="https://landing.ai/about/" rel="noopener noreferrer" target="_blank">Landing AI</a>, which built a platform called LandingLens to help manufacturers improve visual inspection with computer vision. He has also become something of an evangelist for what he calls the <a href="https://www.youtube.com/watch?v=06-AZXmwHjo" target="_blank">data-centric AI movement</a>, which he says can yield “small data” solutions to big issues in AI, including model efficiency, accuracy, and bias.

<strong>The great advances in deep learning over the past decade or so have been powered by ever-bigger models crunching ever-bigger amounts of data. Some people argue that that’s an <a href="https://spectrum.ieee.org/deep-learning-computational-cost" target="_self">unsustainable trajectory</a>. Do you agree that it can’t go on that way?</strong>
</p><p>
<strong>Andrew Ng: </strong>This is a big question. We’ve seen foundation models in NLP [natural language processing]. I’m excited about NLP models getting even bigger, and also about the potential of building foundation models in computer vision. I think there’s lots of signal to still be exploited in video: We have not been able to build foundation models yet for video because of compute bandwidth and the cost of processing video, as opposed to tokenized text. So I think that this engine of scaling up deep learning algorithms, which has been running for something like 15 years now, still has steam in it. Having said that, it only applies to certain problems, and there’s a set of other problems that need small data solutions.
</p><p>
<strong>When you say you want a foundation model for computer vision, what do you mean by that?</strong>
</p><p>
<strong>Ng:</strong> This is a term coined by <a href="https://cs.stanford.edu/~pliang/" rel="noopener noreferrer" target="_blank">Percy Liang</a> and <a href="https://crfm.stanford.edu/" rel="noopener noreferrer" target="_blank">some of my friends at Stanford</a> to refer to very large models, trained on very large data sets, that can be tuned for specific applications. For example, <a href="https://spectrum.ieee.org/open-ais-powerful-text-generating-tool-is-ready-for-business" target="_self">GPT-3</a> is an example of a foundation model [for NLP]. Foundation models offer a lot of promise as a new paradigm in developing machine learning applications, but also challenges in terms of making sure that they’re reasonably fair and free from bias, especially if many of us will be building on top of them.
</p><p>
<strong>What needs to happen for someone to build a foundation model for video?</strong>
</p><p>
<strong>Ng:</strong> I think there is a scalability problem. The compute power needed to process the large volume of images for video is significant, and I think that’s why foundation models have arisen first in NLP. Many researchers are working on this, and I think we’re seeing early signs of such models being developed in computer vision. But I’m confident that if a semiconductor maker gave us 10 times more processor power, we could easily find 10 times more video to build such models for vision.
</p><p>
	Having said that, a lot of what’s happened over the past decade is that deep learning has happened in consumer-facing companies that have large user bases, sometimes billions of users, and therefore very large data sets. While that paradigm of machine learning has driven a lot of economic value in consumer software, I find that that recipe of scale doesn’t work for other industries.
</p><p>
<a href="#top">Back to top</a>
</p><p>
<strong>It’s funny to hear you say that, because your early work was at a consumer-facing company with millions of users.</strong>
</p><p>
<strong>Ng: </strong>Over a decade ago, when I proposed starting the <a href="https://research.google/teams/brain/" rel="noopener noreferrer" target="_blank">Google Brain</a> project to use Google’s compute infrastructure to build very large neural networks, it was a controversial step. One very senior person pulled me aside and warned me that starting Google Brain would be bad for my career. I think he felt that the action couldn’t just be in scaling up, and that I should instead focus on architecture innovation.
</p><p class="pull-quote">
	“In many industries where giant data sets simply don’t exist, I think the focus has to shift from big data to good data. Having 50 thoughtfully engineered examples can be sufficient to explain to the neural network what you want it to learn.”<br/>
	—Andrew Ng, CEO & Founder, Landing AI
</p><p>
	I remember when my students and I published the first 
	<a href="https://nips.cc/" rel="noopener noreferrer" target="_blank">NeurIPS</a> workshop paper advocating using <a href="https://developer.nvidia.com/cuda-zone" rel="noopener noreferrer" target="_blank">CUDA</a>, a platform for processing on GPUs, for deep learning—a different senior person in AI sat me down and said, “CUDA is really complicated to program. As a programming paradigm, this seems like too much work.” I did manage to convince him; the other person I did not convince.
</p><p>
<strong>I expect they’re both convinced now.</strong>
</p><p>
<strong>Ng:</strong> I think so, yes.
</p><p>
	Over the past year as I’ve been speaking to people about the data-centric AI movement, I’ve been getting flashbacks to when I was speaking to people about deep learning and scalability 10 or 15 years ago. In the past year, I’ve been getting the same mix of “there’s nothing new here” and “this seems like the wrong direction.”
</p><p>
<a href="#top">Back to top</a>
</p><p>
<strong>How do you define data-centric AI, and why do you consider it a movement?</strong>
</p><p>
<strong>Ng:</strong> Data-centric AI is the discipline of systematically engineering the data needed to successfully build an AI system. For an AI system, you have to implement some algorithm, say a neural network, in code and then train it on your data set. The dominant paradigm over the last decade was to download the data set while you focus on improving the code. Thanks to that paradigm, over the last decade deep learning networks have improved significantly, to the point where for a lot of applications the code—the neural network architecture—is basically a solved problem. So for many practical applications, it’s now more productive to hold the neural network architecture fixed, and instead find ways to improve the data.
</p><p>
	When I started speaking about this, there were many practitioners who, completely appropriately, raised their hands and said, “Yes, we’ve been doing this for 20 years.” This is the time to take the things that some individuals have been doing intuitively and make it a systematic engineering discipline.
</p><p>
	The data-centric AI movement is much bigger than one company or group of researchers. My collaborators and I organized a 
	<a href="https://neurips.cc/virtual/2021/workshop/21860" rel="noopener noreferrer" target="_blank">data-centric AI workshop at NeurIPS</a>, and I was really delighted at the number of authors and presenters that showed up.
</p><p>
<strong>You often talk about companies or institutions that have only a small amount of data to work with. How can data-centric AI help them?</strong>
</p><p>
<strong>Ng: </strong>You hear a lot about vision systems built with millions of images—I once built a face recognition system using 350 million images. Architectures built for hundreds of millions of images don’t work with only 50 images. But it turns out, if you have 50 really good examples, you can build something valuable, like a defect-inspection system. In many industries where giant data sets simply don’t exist, I think the focus has to shift from big data to good data. Having 50 thoughtfully engineered examples can be sufficient to explain to the neural network what you want it to learn.
</p><p>
<strong>When you talk about training a model with just 50 images, does that really mean you’re taking an existing model that was trained on a very large data set and fine-tuning it? Or do you mean a brand new model that’s designed to learn only from that small data set?</strong>
</p><p>
<strong>Ng: </strong>Let me describe what Landing AI does. When doing visual inspection for manufacturers, we often use our own flavor of <a href="https://developers.arcgis.com/python/guide/how-retinanet-works/" rel="noopener noreferrer" target="_blank">RetinaNet</a>. It is a pretrained model. Having said that, the pretraining is a small piece of the puzzle. What’s a bigger piece of the puzzle is providing tools that enable the manufacturer to pick the right set of images [to use for fine-tuning] and label them in a consistent way. There’s a very practical problem we’ve seen spanning vision, NLP, and speech, where even human annotators don’t agree on the appropriate label. For big data applications, the common response has been: If the data is noisy, let’s just get a lot of data and the algorithm will average over it. But if you can develop tools that flag where the data’s inconsistent and give you a very targeted way to improve the consistency of the data, that turns out to be a more efficient way to get a high-performing system.
</p><p class="pull-quote">
	“Collecting more data often helps, but if you try to collect more data for everything, that can be a very expensive activity.”<br/>
	—Andrew Ng
</p><p>
	For example, if you have 10,000 images where 30 images are of one class, and those 30 images are labeled inconsistently, one of the things we do is build tools to draw your attention to the subset of data that’s inconsistent. So you can very quickly relabel those images to be more consistent, and this leads to improvement in performance.
</p><p>
<strong>Could this focus on high-quality data help with bias in data sets? If you’re able to curate the data more before training?</strong>
</p><p>
<strong>Ng:</strong> Very much so. Many researchers have pointed out that biased data is one factor among many leading to biased systems. There have been many thoughtful efforts to engineer the data. At the NeurIPS workshop, <a href="https://www.cs.princeton.edu/~olgarus/" rel="noopener noreferrer" target="_blank">Olga Russakovsky</a> gave a really nice talk on this. At the main NeurIPS conference, I also really enjoyed <a href="https://neurips.cc/virtual/2021/invited-talk/22281" rel="noopener noreferrer" target="_blank">Mary Gray’s presentation,</a> which touched on how data-centric AI is one piece of the solution, but not the entire solution. New tools like <a href="https://www.microsoft.com/en-us/research/project/datasheets-for-datasets/" rel="noopener noreferrer" target="_blank">Datasheets for Datasets</a> also seem like an important piece of the puzzle.
</p><p>
	One of the powerful tools that data-centric AI gives us is the ability to engineer a subset of the data. Imagine training a machine-learning system and finding that its performance is okay for most of the data set, but its performance is biased for just a subset of the data. If you try to change the whole neural network architecture to improve the performance on just that subset, it’s quite difficult. But if you can engineer a subset of the data you can address the problem in a much more targeted way.
</p><p>
<strong>When you talk about engineering the data, what do you mean exactly?</strong>
</p><p>
<strong>Ng: </strong>In AI, data cleaning is important, but the way the data has been cleaned has often been in very manual ways. In computer vision, someone may visualize images through a <a href="https://jupyter.org/" rel="noopener noreferrer" target="_blank">Jupyter notebook</a> and maybe spot the problem, and maybe fix it. But I’m excited about tools that allow you to have a very large data set, tools that draw your attention quickly and efficiently to the subset of data where, say, the labels are noisy. Or to quickly bring your attention to the one class among 100 classes where it would benefit you to collect more data. Collecting more data often helps, but if you try to collect more data for everything, that can be a very expensive activity.
</p><p>
	For example, I once figured out that a speech-recognition system was performing poorly when there was car noise in the background. Knowing that allowed me to collect more data with car noise in the background, rather than trying to collect more data for everything, which would have been expensive and slow.
</p><p>
<a href="#top">Back to top</a>
</p><p>
<strong>What about using synthetic data, is that often a good solution?</strong>
</p><p>
<strong>Ng: </strong>I think synthetic data is an important tool in the tool chest of data-centric AI. At the NeurIPS workshop, <a href="https://tensorlab.cms.caltech.edu/users/anima/" rel="noopener noreferrer" target="_blank">Anima Anandkumar</a> gave a great talk that touched on synthetic data. I think there are important uses of synthetic data that go beyond just being a preprocessing step for increasing the data set for a learning algorithm. I’d love to see more tools to let developers use synthetic data generation as part of the closed loop of iterative machine learning development.
</p><p>
<strong>Do you mean that synthetic data would allow you to try the model on more data sets?</strong>
</p><p>
<strong>Ng: </strong>Not really. Here’s an example. Let’s say you’re trying to detect defects in a smartphone casing. There are many different types of defects on smartphones. It could be a scratch, a dent, pit marks, discoloration of the material, other types of blemishes. If you train the model and then find through error analysis that it’s doing well overall but it’s performing poorly on pit marks, then synthetic data generation allows you to address the problem in a more targeted way. You could generate more data just for the pit-mark category.

	“In the consumer software Internet, we could train a handful of machine-learning models to serve a billion users. In manufacturing, you might have 10,000 manufacturers building 10,000 custom AI models.”<br/>
	—Andrew Ng
</p><p>
	Synthetic data generation is a very powerful tool, but there are many simpler tools that I will often try first. Such as data augmentation, improving labeling consistency, or just asking a factory to collect more data.
</p><p>
<a href="#top">Back to top</a>
</p><p>
<strong>To make these issues more concrete, can you walk me through an example? When a company approaches <a href="https://landing.ai/" rel="noopener noreferrer" target="_blank">Landing AI</a> and says it has a problem with visual inspection, how do you onboard them and work toward deployment?</strong>
</p><p>
<strong>Ng: </strong>When a customer approaches us we usually have a conversation about their inspection problem and look at a few images to verify that the problem is feasible with computer vision. Assuming it is, we ask them to upload the data to the <a href="https://landing.ai/platform/" rel="noopener noreferrer" target="_blank">LandingLens</a> platform. We often advise them on the methodology of data-centric AI and help them label the data.
</p><p>
	One of the foci of Landing AI is to empower manufacturing companies to do the machine learning work themselves. A lot of our work is making sure the software is fast and easy to use. Through the iterative process of machine learning development, we advise customers on things like how to train models on the platform, when and how to improve the labeling of data so the performance of the model improves. Our training and software supports them all the way through deploying the trained model to an edge device in the factory.
</p><p>
<strong>How do you deal with changing needs? If products change or lighting conditions change in the factory, can the model keep up?</strong>
</p><p>
<strong>Ng:</strong> It varies by manufacturer. There is data drift in many contexts. But there are some manufacturers that have been running the same manufacturing line for 20 years now with few changes, so they don’t expect changes in the next five years. Those stable environments make things easier. For other manufacturers, we provide tools to flag when there’s a significant data-drift issue. I find it really important to empower manufacturing customers to correct data, retrain, and update the model. Because if something changes and it’s 3 a.m. in the United States, I want them to be able to adapt their learning algorithm right away to maintain operations.
</p><p>
	In the consumer software Internet, we could train a handful of machine-learning models to serve a billion users. In manufacturing, you might have 10,000 manufacturers building 10,000 custom AI models. The challenge is, how do you do that without Landing AI having to hire 10,000 machine learning specialists?
</p><p>
<strong>So you’re saying that to make it scale, you have to empower customers to do a lot of the training and other work.</strong>
</p><p>
<strong>Ng: </strong>Yes, exactly! This is an industry-wide problem in AI, not just in manufacturing. Look at health care. Every hospital has its own slightly different format for electronic health records. How can every hospital train its own custom AI model? Expecting every hospital’s IT personnel to invent new neural-network architectures is unrealistic. The only way out of this dilemma is to build tools that empower the customers to build their own models by giving them tools to engineer the data and express their domain knowledge. That’s what Landing AI is executing in computer vision, and the field of AI needs other teams to execute this in other domains.
</p><p>
<strong>Is there anything else you think it’s important for people to understand about the work you’re doing or the data-centric AI movement?</strong>
</p><p>
<strong>Ng: </strong>In the last decade, the biggest shift in AI was a shift to deep learning. I think it’s quite possible that in this decade the biggest shift will be to data-centric AI. With the maturity of today’s neural network architectures, I think for a lot of the practical applications the bottleneck will be whether we can efficiently get the data we need to develop systems that work well. The data-centric AI movement has tremendous energy and momentum across the whole community. I hope more researchers and developers will jump in and work on it.

Engineers and designers can do only so much to <a href="https://spectrum.ieee.org/ibm-introduces-the-worlds-first-2nm-node-chip" target="_self">miniaturize transistors</a> and <a href="https://spectrum.ieee.org/cerebras-giant-ai-chip-now-has-a-trillions-more-transistors" target="_self">pack as many of them as possible into chips</a>. So they’re turning to other approaches to chip design, incorporating technologies like AI into the process.</p><p>Samsung, for instance, is <a href="https://spectrum.ieee.org/processing-in-dram-accelerates-ai" target="_self">adding AI to its memory chips</a> to enable processing in memory, thereby saving energy and speeding up machine learning. Speaking of speed, Google’s TPU V4 AI chip has <a href="https://spectrum.ieee.org/heres-how-googles-tpu-v4-ai-chip-stacked-up-in-training-tests" target="_self">doubled its processing power</a> compared with that of  its previous version.</p><p>But AI holds still more promise and potential for the semiconductor industry. To better understand how AI is set to revolutionize chip design, we spoke with <a href="https://www.linkedin.com/in/heather-gorr-phd" rel="noopener noreferrer" target="_blank">Heather Gorr</a>, senior product manager for <a href="https://www.mathworks.com/" rel="noopener noreferrer" target="_blank">MathWorks</a>’ MATLAB platform.</p><p><strong>How is AI currently being used to design the next generation of chips?</strong></p><p><strong>Heather Gorr:</strong> AI is such an important technology because it’s involved in most parts of the cycle, including the design and manufacturing process. There’s a lot of important applications here, even in the general process engineering where we want to optimize things. I think defect detection is a big one at all phases of the process, especially in manufacturing. But even thinking ahead in the design process, [AI now plays a significant role] when you’re designing the light and the sensors and all the different components. There’s a lot of anomaly detection and fault mitigation that you really want to consider.</p><p class="shortcode-media shortcode-media-rebelmouse-image rm-resized-container rm-resized-container-25 rm-float-left" data-rm-resized-container="25%" style="float: left;">

So, looking back at that historical data of when you’ve had those moments where maybe it took a bit longer than expected to manufacture something, you can take a look at all of that data and use AI to try to identify the proximate cause or to see  something that might jump out even in the processing and design phases. We think of AI oftentimes as a predictive tool, or as a robot doing something, but a lot of times you get a lot of insight from the data through AI.</p><p><strong>What are the benefits of using AI for chip design?</strong></p><p><strong>Gorr:</strong> Historically, we’ve seen a lot of physics-based modeling, which is a very intensive process. We want to do a <a href="https://en.wikipedia.org/wiki/Model_order_reduction" rel="noopener noreferrer" target="_blank">reduced order model</a>, where instead of solving such a computationally expensive and extensive model, we can do something a little cheaper. You could create a surrogate model, so to speak, of that physics-based model, use the data, and then do your parameter sweeps, your optimizations, your <a href="https://www.ibm.com/cloud/learn/monte-carlo-simulation" rel="noopener noreferrer" target="_blank">Monte Carlo simulations</a> using the surrogate model. That takes a lot less time computationally than solving the physics-based equations directly. So, we’re seeing that benefit in many ways, including the efficiency and economy that are the results of iterating quickly on the experiments and the simulations that will really help in the design.</p><p><strong>So it’s like having a digital twin in a sense?</strong></p><p><strong>Gorr:</strong> Exactly. That’s pretty much what people are doing, where you have the physical system model and the experimental data. Then, in conjunction, you have this other model that you could tweak and tune and try different parameters and experiments that let sweep through all of those different situations and come up with a better design in the end.</p><p><strong>So, it’s going to be more efficient and, as you said, cheaper?</strong></p><p><strong>Gorr:</strong> Yeah, definitely. Especially in the experimentation and design phases, where you’re trying different things. That’s obviously going to yield dramatic cost savings if you’re actually manufacturing and producing [the chips]. You want to simulate, test, experiment as much as possible without making something using the actual process engineering.</p><p><strong>We’ve talked about the benefits. How about the drawbacks?</strong></p><p><strong>Gorr: </strong>The [AI-based experimental models] tend to not be as accurate as physics-based models. Of course, that’s why you do many simulations and parameter sweeps. But that’s also the benefit of having that digital twin, where you can keep that in mind—it’s not going to be as accurate as that precise model that we’ve developed over the years.</p><p>Both chip design and manufacturing are system intensive; you have to consider every little part. And that can be really challenging. It’s a case where you might have models to predict something and different parts of it, but you still need to bring it all together.</p><p>One of the other things to think about too is that you need the data to build the models. You have to incorporate data from all sorts of different sensors and different sorts of teams, and so that heightens the challenge.</p><p><strong>How can engineers use AI to better prepare and extract insights from hardware or sensor data?</strong></p><p><strong>Gorr: </strong>We always think about using AI to predict something or do some robot task, but you can use AI to come up with patterns and pick out things you might not have noticed before on your own. People will use AI when they have high-frequency data coming from many different sensors, and a lot of times it’s useful to explore the frequency domain and things like data synchronization or resampling. Those can be really challenging if you’re not sure where to start.</p><p>One of the things I would say is, use the tools that are available. There’s a vast community of people working on these things, and you can find lots of examples [of applications and techniques] on <a href="https://github.com/" rel="noopener noreferrer" target="_blank">GitHub</a> or <a href="https://www.mathworks.com/matlabcentral/" rel="noopener noreferrer" target="_blank">MATLAB Central</a>, where people have shared nice examples, even little apps they’ve created. I think many of us are buried in data and just not sure what to do with it, so definitely take advantage of what’s already out there in the community. You can explore and see what makes sense to you, and bring in that balance of domain knowledge and the insight you get from the tools and AI.</p><p><strong>What should engineers and designers consider wh</strong><strong>en using AI for chip design?</strong></p><p><strong>Gorr:</strong> Think through what problems you’re trying to solve or what insights you might hope to find, and try to be clear about that. Consider all of the different components, and document and test each of those different parts. Consider all of the people involved, and explain and hand off in a way that is sensible for the whole team.</p><p><strong>How do you think AI will affect chip designers’ jobs?</strong></p><p><strong>Gorr:</strong> It’s going to free up a lot of human capital for more advanced tasks. We can use AI to reduce waste, to optimize the materials, to optimize the design, but then you still have that human involved whenever it comes to decision-making. I think it’s a great example of people and technology working hand in hand. It’s also an industry where all people involved—even on the manufacturing floor—need to have some level of understanding of what’s happening, so this is a great industry for advancing AI because of how we test things and how we think about them before we put them on the chip.</p><p><strong>How do you envision the future of AI and chip design?</strong></p><p><strong>Gorr</strong><strong>:</strong> It’s very much dependent on that human element—involving people in the process and having that interpretable model. We can do many things with the mathematical minutiae of modeling, but it comes down to how people are using it, how everybody in the process is understanding and applying it. Communication and involvement of people of all skill levels in the process are going to be really important. We’re going to see less of those superprecise predictions and more transparency of information, sharing, and that digital twin—not only using AI but also using our human knowledge and all of the work that many people have done over the years.</p>]]></description><pubDate>Tue, 08 Feb 2022 14:00:01 +0000</pubDate><guid>https://spectrum.ieee.org/ai-chip-design-matlab</guid><category>Chip-fabrication</category><category>Matlab</category><category>Moores-law</category><category>Chip-design</category><category>Ai</category><category>Digital-twins</category><dc:creator>Rina Diane Caballar</dc:creator><media:content medium="image" type="image/jpeg" url="https://spectrum.ieee.org/media-library/layered-rendering-of-colorful-semiconductor-wafers-with-a-bright-white-light-sitting-on-one.jpg?id=29285079&amp;width=980"></media:content></item><item><title>Atomically Thin Materials Significantly Shrink Qubits</title><link>https://spectrum.ieee.org/2d-hbn-qubit</link><description><![CDATA[

Of these challenges two critical issues stand out: miniaturization and qubit quality.</p><p>IBM has adopted the superconducting qubit road map of <a href="https://spectrum.ieee.org/ibms-envisons-the-road-to-quantum-computing-like-an-apollo-mission" target="_self">reaching a 1,121-qubit processor by 2023</a>, leading to the expectation that 1,000 qubits with today’s qubit form factor is feasible. However, current approaches will require very large chips (50 millimeters on a side, or larger) at the scale of small wafers, or the use of chiplets on multichip modules. While this approach will work, the aim is to attain a better path toward scalability.</p><p>Now researchers at <a href="https://www.nature.com/articles/s41563-021-01187-w" rel="noopener noreferrer" target="_blank">MIT have been able to both reduce the size of the qubits</a> and done so in a way that reduces the interference that occurs between neighboring qubits. The MIT researchers have increased the number of superconducting qubits that can be added onto a device by a factor of 100.</p><p>“We are addressing both qubit miniaturization and quality,” said <a href="https://equs.mit.edu/william-d-oliver/" rel="noopener noreferrer" target="_blank">William Oliver</a>, the director for the <a href="https://cqe.mit.edu/" target="_blank">Center for Quantum Engineering</a> at MIT. “Unlike conventional transistor scaling, where only the number really matters, for qubits, large numbers are not sufficient, they must also be high-performance. Sacrificing performance for qubit number is not a useful trade in quantum computing. They must go hand in hand.”</p><p>The key to this big increase in qubit density and reduction of interference comes down to the use of two-dimensional materials, in particular the 2D insulator hexagonal boron nitride (hBN). The MIT researchers demonstrated that a few atomic monolayers of hBN can be stacked to form the insulator in the capacitors of a superconducting qubit.</p><p>Just like other capacitors, the capacitors in these superconducting circuits take the form of a sandwich in which an insulator material is sandwiched between two metal plates. The big difference for these capacitors is that the superconducting circuits can operate only at extremely low temperatures—less than 0.02 degrees above absolute zero (-273.15 °C).</p><p class="shortcode-media shortcode-media-rebelmouse-image rm-resized-container rm-resized-container-25 rm-float-left" data-rm-resized-container="25%" style="float: left;">

<small class="image-media media-caption" placeholder="Add Photo Caption..." style="max-width: 100%;">Superconducting qubits are measured at temperatures as low as 20 millikelvin in a dilution refrigerator.</small><small class="image-media media-photo-credit" placeholder="Add Photo Credit..." style="max-width: 100%;">Nathan Fiske/MIT</small></p><p>In that environment, insulating materials that are available for the job, such as PE-CVD silicon oxide or silicon nitride, have quite a few defects that are too lossy for quantum computing applications. To get around these material shortcomings, most superconducting circuits use what are called coplanar capacitors. In these capacitors, the plates are positioned laterally to one another, rather than on top of one another.</p><p>As a result, the intrinsic silicon substrate below the plates and to a smaller degree the vacuum above the plates serve as the capacitor dielectric. Intrinsic silicon is chemically pure and therefore has few defects, and the large size dilutes the electric field at the plate interfaces, all of which leads to a low-loss capacitor. The lateral size of each plate in this open-face design ends up being quite large (typically 100 by 100 micrometers) in order to achieve the required capacitance.</p><p>In an effort to move away from the large lateral configuration, the MIT researchers embarked on a search for an insulator that has very few defects and is compatible with superconducting capacitor plates.</p><p>“We chose to study hBN because it is the most widely used insulator in 2D material research due to its cleanliness and chemical inertness,” said colead author <a href="https://equs.mit.edu/joel-wang/" rel="noopener noreferrer" target="_blank">Joel Wang</a>, a research scientist in the Engineering Quantum Systems group of the MIT Research Laboratory for Electronics. </p><p>On either side of the hBN, the MIT researchers used the 2D superconducting material, niobium diselenide. One of the trickiest aspects of fabricating the capacitors was working with the niobium diselenide, which oxidizes in seconds when exposed to air, according to Wang. This necessitates that the assembly of the capacitor occur in a glove box filled with argon gas.</p><p>While this would seemingly complicate the scaling up of the production of these capacitors, Wang doesn’t regard this as a limiting factor.</p><p>“What determines the quality factor of the capacitor are the two interfaces between the two materials,” said Wang. “Once the sandwich is made, the two interfaces are “sealed” and we don’t see any noticeable degradation over time when exposed to the atmosphere.”</p><p>This lack of degradation is because around 90 percent of the electric field is contained within the sandwich structure, so the oxidation of the outer surface of the niobium diselenide does not play a significant role anymore. This ultimately makes the capacitor footprint much smaller, and it accounts for the reduction in cross talk between the neighboring qubits.</p><p>“The main challenge for scaling up the fabrication will be the wafer-scale growth of hBN and 2D superconductors like [niobium diselenide], and how one can do wafer-scale stacking of these films,” added Wang.</p><p>Wang believes that this research has shown 2D hBN to be a good insulator candidate for superconducting qubits. He says that the groundwork the MIT team has done will serve as a road map for using other hybrid 2D materials to build superconducting circuits.</p>]]></description><pubDate>Mon, 07 Feb 2022 16:12:05 +0000</pubDate><guid>https://spectrum.ieee.org/2d-hbn-qubit</guid><category>Quantum-computing</category><category>2d-materials</category><category>Ibm</category><category>Qubits</category><category>Hexagonal-boron-nitride</category><category>Superconducting-qubits</category><category>Mit</category><dc:creator>Dexter Johnson</dc:creator><media:content medium="image" type="image/jpeg" url="https://spectrum.ieee.org/media-library/a-golden-square-package-holds-a-small-processor-sitting-on-top-is-a-metal-square-with-mit-etched-into-it.jpg?id=29281587&amp;width=980"></media:content></item></channel></rss>
