A Rice University researcher is giving autonomous vehicles an “extra set of eyes.”

Current autonomous vehicles (AVs) can have an incomplete view of their surroundings, and challenges like pedestrian movement, low-light conditions and adverse weather only compound these visibility limitations.

Kun Woo Cho, a postdoctoral researcher in the lab of Rice professor of electrical and computer engineering Ashutosh Sabharwal, has developed EyeDAR to help address such issues and enhance the vehicles’ sensing accuracy. Her research was supported in part by the National Science Foundation.

The EyeDAR is an orange-sized, low-power, millimeter-wave radar that could be placed at streetlights and intersections. Its design was inspired by that of the human eye. Researchers envision that the low-cost sensors could help ensure that AVs always pick up on emergent obstacles, even when the vehicles are not within proper range for their onboard sensors and when visibility is limited.

“Current automotive sensor systems like cameras and lidar struggle with poor visibility such as you would encounter due to rain or fog or in low-lighting conditions,” Cho said in a news release. “Radar, on the other hand, operates reliably in all weather and lighting conditions and can even see through obstacles.”

Signals from a typical radar system scatter when they encounter an obstacle. Some of the signal is reflected back to the source, but most of it is often lost. In the case of AVs, this means that "pedestrians emerging from behind large vehicles, cars creeping forward at intersections or cyclists approaching at odd angles can easily go unnoticed," according to Rice.

EyeDAR, however, works to capture lost radar reflections, determine their direction and report them back to the AV in a sequence of 0s and 1s.

“Like blinking Morse code,” Cho added. “EyeDAR is a talking sensor⎯it is a first instance of integrating radar sensing and communication functionality in a single design.”

After testing, EyeDAR was able to resolve target directions 200 times faster than conventional radar designs.

While EyeDAR currently targets risks associated with AVs, particularly in high-traffic urban areas, researchers also believe the technology behind it could complement artificial intelligence efforts and be integrated into robots, drones and wearable platforms.

“EyeDAR is an example of what I like to call ‘analog computing,’” Cho added in the release. “Over the past two decades, people have been focusing on the digital and software side of computation, and the analog, hardware side has been lagging behind. I want to explore this overlooked analog design space.”

Digital Health Institute's new exec director aims to lead innovation and commercialization efforts

new hire

Though our existences have become deeply entangled with technology, our health has been slower to catch up. The creation late last year of the Digital Health Institute was a major step into the future for both Rice University and Houston Methodist, for whom the institute is a joint venture.

The latest news for the Digital Health Institute is the appointment of Pothik Chatterjee to the role of executive director.

“The Digital Health Institute’s collaborative model is uniquely powerful,” Chatterjee told Rice University’s office of media relations. “By bringing together clinicians, engineers and entrepreneurs, we’re building an ecosystem designed to transform how care is delivered and experienced.”

Chatterjee’s role is to help grow the collaboration between the institutions, but the Digital Health Institute already boasts more than 20 active projects, each of which pairs Rice faculty and Houston Methodist clinicians.

“Research is great, but what we really want at the Digital Health Institute is to translate those research findings into products and services that can be used at the patient's bedside,” Chatterjee explained to InnovationMap.

Once the research is in place, it’s up to Chatterjee to find commercial opportunities within the research portfolio. Those include everything from hospital-grade medical imaging wearables to the creation of digital twins for patients to help better treat them.

“As we move from vision to execution, Pothik’s expertise will be essential in helping us strengthen the institutional alignment needed to deliver at scale,” Dr. Khurram Nasir, Houston Methodist’s William A. Zoghbi Centennial Chair in Cardiovascular Medicine and division chief of cardiovascular prevention and wellness, told Rice. “From my vantage point of a health system, the real value lies not just in innovation, but in implementation.”

Nasir’s co-founder is Ashutosh Sabharwal, Rice’s Ernest Dell Butcher Professor of Engineering and professor of electrical and computer engineering.

“The Digital Health Institute is a key step toward advancing health and health care for the benefit of humanity,” Sabharwal said. “We’re thrilled to welcome Pothik to our growing team. His background in health care innovation, research administration and venture investing will be instrumental in translating cutting-edge research into impactful digital health solutions. From leading innovation strategy and forging strong partnerships to driving fundraising and grant development, his leadership will help shape the institute’s long-term success.”

Though Chatterjee has previously worked around the country, including in Boston and Baltimore, he says he believes Houston is uniquely positioned to thrive in the digital health space.

“Houston is the best place to do it, because we have Rice and Houston Methodist,” he told InnovationMap. “[People] want to help keep that innovation in Houston, not just send it off to Silicon Valley or New York or Boston. There seems to be a lot of appetite from the philanthropic community to have homegrown Houston digital health innovation.”

collaboration station

Rice University and Houston Methodist have established through a multi-year joint effort the Digital Health Institute, which aims to transform healthcare through advanced technology and the collaborative expertises of the university and hospital.

Rice’s leadership in engineering, digital health and artificial intelligence will combine with Houston Methodist’s academic medicine and research infrastructure.

“This partnership embodies Rice’s bold vision to lead at the forefront of innovation in health and responsible AI,” Rice President Reginald DesRoches says in a news release. “By combining our strengths with Houston Methodist, we are creating a transformative platform to address critical challenges in healthcare with solutions that are ethical, accessible and impactful. This initiative exemplifies our commitment to driving interdisciplinary collaboration and advancing global health for the benefit of humanity.”

Leading the initiative will be Rice’s Ashutosh Sabharwal, the Ernest Dell Butcher Professor of Engineering and professor of electrical and computer engineering, and Houston Methodist’s Dr. Khurram Nasir, the Centennial Chair in Cardiovascular Medicine, and Dr. William Zoghbi, division chief of cardiovascular prevention and wellness. Rice and Houston Methodist have worked previously with the Center for Neural Systems Restoration that opened earlier this year and the Center for Human Performance that was established in 2022.

The Digital Health Institute allows for both institutions to share data, and resources that focus on key areas like the early detection through AI algorithms for early diagnosis of cancer, infections, cardiovascular diseases and other conditions, predictive analytics that utilize real-time monitoring that can predict and prevent events such as strokes and heart failure, and the development of novel sensors, wearables and ingestibles to innovate new remote monitoring and care pathways.

The Digital Health Institute will also work to utilize more personalized medicine efforts, developments of new novel and assistive technologies, expansion of telemedicine, and proactive self-care management through AI-driven patient self-management.

“This partnership between our institutions marks a bold new chapter in driving meaningful innovation at the intersection of healthcare and technology through solutions that are both visionary and practical,” Dr. Marc Boom, president and CEO of Houston Methodist, adds. “Our long-standing relationship with Rice University has produced impactful collaborations, but this initiative is by far the most transformative endeavor in our shared commitment of leading medicine through innovation.”

Houston organizations issue seed grants to fuel AI-driven equity, digital health innovation

fresh funding

Three Houston organizations have doled out seed grants for research initiatives focused on digital health and equity.

Rice University's Educational and Research Initiatives for Collaborative Health (ENRICH) office — in partnership with Baylor College of Medicine and the Houston Methodist Academic Institute — has awarded a total of $50,000 to two projects. BCM and Rice announced three other grants earlier this year.

The seed grants were deployed earlier this year at the Health Equity Workshop from Rice’s Digital Health Initiative and chaired by Momona Yamagami, an assistant professor of electrical and computer engineering at Rice.

“To achieve equitable health outcomes, a comprehensive approach is essential — one that spans all phases of digital health from technology design and development to implementation, dissemination and long-term sustainability,” says Ashutosh Sabharwal, who leads the Digital Health Initiative and serves as Rice’s Ernest Dell Butcher Professor of Engineering and a professor of electrical and computer engineering, in a news release.

Both the workshop and the grant opportunity help to allow collaboration between researchers and health care providers working on health equity research across disciplines.

“This seed grant not only fosters interdisciplinary collaborations between Rice University and the Texas Medical Center but also enables us to leverage our combined knowledge to enhance innovations in health equity and digital health, ultimately creating impactful solutions for improving patient care,” adds Sharon Pepper, executive director of ENRICH.

The two projects receiving funding, according to Rice's release, include:

  • Evaluating Equity and Community-Level Vulnerabilities in the Use of Generative Artificial Intelligence-based Symptom Checkers for Self-diagnosis — Using AI-based symptom checkers, the project aims to mitigate vulnerabilities for patients using and improve data precision specifically when it comes to patients' social and cultural differences.
  • Al-Driven ECG Analysis for Equitable Cardiovascular Risk Assessment and Prevention: Leveraging Transformer Models and Big Data to Reduce Health Disparities — Also backed by AI, this project will harness the untapped potential of electrocardiogram data for improving cardiovascular risk assessment, hopefully reducing cost and invasiveness of the standard practice of care.

Rice lands federal funding for new 5G testing framework

money moves

A team of Rice University engineers has secured a $1.9 million grant from the U.S. Department of Commerce’s National Telecommunications and Information Administration to develop a new way to test 5G networks.

The project will focus on testing 5G networks for software-centric architectures, according to a statement from Rice. The funds come from the NTIA's most recent round of grants, totaling about $80 million, as part of the $1.5 billion Public Wireless Supply Chain Innovation Fund. Other awards went to Virginia Tech, Northeastern University, DISH Wireless, and more.

The project at Rice will be led by Rahman Doost-Mohammady, an assistant research professor of electrical and computer engineering; and Ashutosh Sabharwal, the Ernest Dell Butcher Professor of Engineering and chair of the Department of Electrical and Computer Engineering. Santiago Segarra, assistant professor of electrical and computer engineering and an expert in machine learning for wireless network design, is also a co-principal investigator on this project.

"Current testing methodologies for wireless products have predominantly focused on the communication dimension, evaluating aspects such as load testing and channel emulation,” said Doost-Mohammady said in a statement. “But with the escalating trend toward software-based wireless products, it’s imperative that we take a more holistic approach to testing."

The new framework will be used to "assess the stability, interoperability, energy efficiency and communication performance of software-based machine learning-enabled 5G radio access networks (RANs)," according to Rice, known as ETHOS.

Once created, the team of researchers will use the framework for extensive testing using novel machine learning algorithms for 5G RAN with California-based NVIDIA's Aerial Research Cloud (ARC) platform. The team also plans to partner with other industry contacts in the future, according to Rice.

“The broader impacts of this project are far-reaching, with the potential to revolutionize software-based and machine learning-enabled wireless product testing by making it more comprehensive and responsive to the complexities of real-world network environments,” Sabharwal said in the statement. “By providing the industry with advanced tools to evaluate and ensure the stability, energy efficiency and throughput of their products, our research is poised to contribute to the successful deployment of 5G and beyond wireless networks.”

Late last year, the Houston location of Greentown Labs also landed funds from the Department of Commerce. The climatetech startup incubator was named to of the Economic Development Administration's 10th cohort of its Build to Scale program and will receive $400,000 with a $400,000 local match confirmed.

5 Houston inventors named fellows of a prestigious international program

top researchers

The National Academy of Inventors has recognized 175 scientists from across the world as NAI Fellows — and five of those inventors are based at Houston institutions.

The program honors academic inventors who, according to NAI, "have demonstrated a spirit of innovation in creating or facilitating outstanding inventions that have made a tangible impact on quality of life, economic development and the welfare of society."

The five Houston inventors join the ranks of a group of individuals who have generated over 13,000 licensed technologies and companies, and created more than 19 million jobs, according to the announcement.

These are the scientists from Houston organizations:

  • Ananth Annapragada of Baylor College of Medicine is professor of radiology and obstetrics and gynecology, vice chief of research and director of basic research at Baylor College of Medicine and Texas Children's Hospital as well as a member of the Dan L Duncan Comprehensive Cancer Center.
  • Ronald Biediger of the Texas Heart Institute is associate director of chemistry, Wafic Said Molecular Cardiology Research Laboratories and leading a group of chemists developing small molecule integrin antagonists and agonists for use as therapies, or as adjuncts to cell based therapies, for heart, lung and vascular disease
  • Mark Clarke of the University of Houston is associate provost for faculty development and faculty affairs at the University of Houston.
  • Ashutosh Sabharwal of Rice University is professor and Ph.D of electrical engineering and was named Fellow of the Institute of Electrical and Electronics Engineers in 2014 for contributions to the theory and experimentation of wireless systems and networks.
  • Jia Zhou of The University of Texas Medical Branch is professor in the Department Pharmacology and Toxicology focusing on drug discovery of bioactive molecules to probe biological systems or act as potential therapeutic agents in neuroscience, cancer/inflammation, infectious diseases, and other human conditions.

The new class of inventors will be inducted on June 8 at the 10th Annual Meeting of the National Academy of Inventors in Tampa, Florida.

These scientists have already established dozens of patents between the five of them across fields and industries. Clarke specifically holds 13 U.S. patents, seven NASA technology innovation awards, and has founded two life science startup companies to commercialize his technologies, according to a news release from UH.

"Most faculty inventors, including myself, do not begin their research careers focused on creating or commercializing new technologies, nor do they usually know where to start when presented with such an opportunity," Clarke says in the release. "Helping faculty members and students transition fundamental discoveries into commercially valuable technologies and products is not only a key part of our mission as a Tier One research university, it is critical to our region's economic prosperity and ensuring that the U.S. remains competitive in an innovation-driven global economy."

From BCM, Annapragada holds 15 patents in the United States and close to 100 worldwide. The majority of his patents are in next generation imaging technologies, CT vascular imaging, and MR molecular imaging, according to a BCM release, and Annapragada is the founder of two active startup companies — Alzeca Inc. and Sensulin LLC.

Houston Methodist receives record $110M gift, names future tower

historic gift

Houston Methodist has received the largest gift in the health system's history to establish new funds for neurological, neuroscience, and women’s health research and treatment.

The $110 million gift comes from Houston-based The Brockman Medical Research Foundation, which supports education and research in the science, medicine and healthcare fields. In response, Houston Methodist announced that it will name its forthcoming 26-story hospital facility the Brockman Centennial Tower.

The tower’s entrance will be named the Anna Margaret Bellows Centennial Hall to honor Anna Margaret Bellows, a young camper who died during the Camp Mystic flooding last summer.

“This extraordinary gift accelerates discovery and transforms how care is delivered,” Dr. Marc Boom, president and CEO of Houston Methodist, said in a news release. “We are grateful to The Brockman Medical Research Foundation for its incredible generosity and vision that will help change the lives of generations of patients. Naming Centennial Tower in recognition of this gift reflects the scale of this commitment and its impact on the future of neuroscience, neurological care and women’s health.”

The gift will be divided into two parts:

  • $100 million will go toward creating an innovation fund within the Houston Methodist Academic Institute and the Houston Methodist Neurological Institute
  • $10 million will be devoted to Houston Methodist's Department of Obstetrics and Gynecology

“This tremendous gift will accelerate translational research that broadens our understanding of neurological and other diseases,” Dr. Jenny Chang, president and CEO of the Houston Methodist Academic Institute, added in the release. “It will allow us to leverage state-of-the-art platforms to detect, diagnose and deliver therapeutics, keeping patient care at the center of our mission.”

The Brockman Centennial Tower is expected to open next year in the Texas Medical Center. Spanning more than 1 million square feet, it will house 400 patient beds, an expanded emergency department, new operating rooms and a rooftop garden. It will be connected to Houston Methodist's flagship Paula and Joseph C. “Rusty” Walter III Tower, which opened in 2018. The Centennial Tower was estimated to cost $1.4 billion when announced in 2022.

In addition to the news of the Brockman gift, Houston Methodist also announced this month that it has launched the Houston Methodist Center for Cell and Gene Therapy and tapped an internationally recognized scientist as its leader.

The new center is focused on discovering and developing innovative and cost-effective therapies for a variety of congenital and acquired diseases, including cancer, HIV and cardiovascular disease.

Dr. Malcolm Brenner has been named as the center's inaugural leader and will assume the role starting in October. He will work alongside scientists and support staff from Baylor College of Medicine and Texas Children's Hospital.

Brenner is a professor of pediatrics, medicine, molecular and human genetics and translational biology at Baylor College of Medicine. He is known for making early advances in using bone marrow transplantation as a form of cell therapy and in engineered immune-cell treatments for cancer and infections, according to a release from Houston Methodist.

“Malcolm Brenner is a pioneer in the field of cell and gene therapy and is uniquely qualified to lead Houston Methodist’s research efforts in this field,” Chang added. “His vision and leadership will play a pivotal role in advancing our work in this space.”

Report: Houston reclaims top 10 ranking among America's best cities

Houston has made a triumphant return to America's 10 best cities for 2026, certifying the city is a cornerstone of the country's growth and economic prosperity.

Houston ranks No. 9 nationwide in the annual "America's Best Cities" report from Canada-based real estate and tourism marketing firm Resonance Consultancy. Each year, the report ranks the relative qualities of livability, cultural "lovability," and economic prosperity in 393 American cities with metropolitan populations of 500,000 or more.

Dallas surpassed H-Town as the No. 8 best city in America, and the Lone Star State boasts a strong presence among the top 25. Austin and San Antonio, respectively, were named the 11th and 24th best American cities this year.

Previously, Houston was dubbed the 13th best American city in 2025, down from its No. 10 ranking in the 2024 report.

Rather than profiling each individual city like in past reports, the 2026 edition focuses on regional and state prosperity. Texas' economic dominance is second only to Florida's, and the state's growth is solidified by the Dallas-Houston-Austin "triangle," where each metro has its own distinct economic identity, but when combined "form one of the most formidable regional economies in the world."

"In our 2026 survey, Dallas ranks third nationally as the place Americans believe offers the best job opportunities, Austin fifth, and Houston seventh," the report's author wrote. "That concentration of perceived economic opportunity in a single state is unmatched, and the GDP data confirms it isn’t just perception."

After being named one of the best places to start a business or a career earlier in 2026, Houston has continued to punch above its weight with its success in tourism, education, and housing growth.

Overall, the report found a correlation between a city's population growth and its latest ranking, with bigger cities appearing higher up on the list. The top three best American cities — New York, Los Angeles, and Chicago — are coincidentally the three largest metros, while Dallas and Houston are the fourth and fifth largest but appear eighth and ninth on the list.

"Scale compounds at the large city level — more people generate more economic activity, more cultural infrastructure, more employer presence, which attracts more people," the report said.

The top 10 best cities in America for 2026 are:

  • No. 1 – New York
  • No. 2 – Los Angeles
  • No. 3 – Chicago
  • No. 4 – Miami
  • No. 5 – San Francisco
  • No. 6 – Seattle
  • No. 7 – Las Vegas
  • No. 8 – Dallas
  • No. 9 – Houston
  • No. 10 – Boston

New probe into Tesla after vehicle slams into Houston-area home at high speed

Tesla Talk

The top U.S. auto regulator opened an investigation Monday, June 22, after a Tesla using an automated driving feature slammed into a Texas home at high speed and killed a 76-year-old woman standing inside.

The National Highway Traffic Safety Administration said it's opening a special investigation into the Tesla Model 3 crash on Friday near Houston, a significant probe because the car was using technology that Elon Musk considers key to the company's future.

The Tesla CEO is rolling out robotaxis using automated software in several U.S. cities this year and plans to invite Tesla owners to put their cars into the fleet using the same system across the country.

The driver told the Harris County Sheriff's Office that he was using the technology, according to a police report on the crash, but it's not clear what role, if any, it played in the incident.

Tesla did not respond to a request for comment but the head of the company's artificial intelligence efforts suggested on social media later Monday that the self-driving feature was not to blame.

“In this case, the driver manually overrode self-driving by pressing the accelerator all the way to 100% of the accel pedal in this residential area,” wrote Ashok Elluswamy on X, the platform that is now part of Musk's rocket company, SpaceX. “They reached a speed of 73 mph during the crash, and had the accelerator pressed even after the crash.”

The police report noted that the driver was not drunk and is cooperating. It identified the woman killed as Martha Avila.

Video obtained by KHOU-TV shows the car traveling at top speed over the front lawn of a brick home in Katy, then ramming into a front room. The next shot shows the car encased in the home amid piles of crumbling plaster, split beams and bits of furniture.

The auto safety regulator, known as NHTSA, has launched several investigations into Tesla, including one late last year into 58 incidents in which Teslas reportedly violated traffic safety laws while using self-driving technology, leading to more than a dozen crashes and fires and nearly two dozen injuries.

A few months earlier, the NHTSA opened an investigation into why Tesla apparently had not been reporting crashes promptly as required.

As for special crash investigations, the NHTSA has opened 46 involving Teslas using self-driving or driver-assistance technology over the past decade, according to the agency's records. In more than a dozen of those crashes, at least one person — a driver, passenger or pedestrian — was killed.

Tesla stock fell sharply early last year as car sales plunged amid a boycott of Musk after he waded into politics, leading President Donald Trump's budget-cutting Department of Government Efficiency initiative and embracing European extremist candidates.

Musk has since shifted the Tesla story to one less about car sales and more about AI and robotaxis, and done so successfully. The stock is up 16% in the past year.
