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.”

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.

New UT Austin med center, anchored by MD Anderson, gets $1 billion gift

Future of Health

A donation announced Tuesday, April 21, breaks a major record at the University of Texas at Austin. Michael and Susan Dell are now UT Austin's first supporters to give $1 billion. In response, the university will create the UT Dell Campus for Advanced Research and the UT Dell Medical Center to "advance human health," per a press release.

The release also records "significant support" for undergraduate scholarships, student housing, and the Texas Advanced Computing Center for supercomputing research.

Both the new research campus and the UT Dell Medical Center will integrate advanced computing into their research and practices. At the medical center, the university hopes that will lead to "earlier detection, more precise and personalized care, and better health outcomes." The University of Texas MD Anderson Cancer Center will also be integrated into the new medical center.

That comes with a numeric goal measured in 10s: raise $10 billion and rank among the top 10 medical centers in the U.S., both in the next decade.

In the shorter term, the university will break ground on the medical center with architecture firm Skidmore, Owings & Merrill (SOM) "later this year."

“UT Austin, where Dell Technologies was founded from a dorm room, has always been a place where bold ideas become real-world impact,” said Michael and Susan Dell in a joint statement.

They continued, “What makes this moment so meaningful is the opportunity to build something that brings every part of the journey together — from how students learn, to how discoveries are made, to how care reaches families. By bringing together medicine, science and computing in one campus designed for the AI era, UT can create more opportunity, deliver better outcomes, and build a stronger future for communities across Texas and beyond.”

This is the second major gift this year for the planned multibillion-dollar medical center. In January, Tench Coxe, a former venture capitalist who’s a major shareholder in chipmaking giant Nvidia, and Simone Coxe, co-founder and former CEO of the Blanc & Otus PR firm, contributed $100 million$100 million.

Baylor scientist lands $2M grant to explore links between viruses and Alzheimer’s

Alzheimer’s research

A Baylor College of Medicine scientist will begin exploring the possible link between Alzheimer’s disease and viral infections thanks to a $2 million grant awarded in March.

Dr. Ryan S. Dhindsa is an assistant professor of pathology & immunology at Baylor and a principal investigator at Texas Children’s Duncan Neurological Research Institute (Duncan NRI). He hypothesizes that Alzheimer’s may have some link to previous viral infections contracted by the patient. To study this intriguing possibility, the American Brain Foundation has gifted him the Cure One, Cure Many award in neuroinflammation.

“It is an honor to receive this support from the Cure One, Cure Many Award. Viral infections are emerging as a major, underappreciated driver of Alzheimer's disease, and this award will allow our team to conduct the most comprehensive screen of viral exposures and host genetics in Alzheimer's to date, spanning over a million individuals,” Dhindsa said in a news release. “Our goal is to identify which viruses matter most, why some people are more vulnerable than others, and ultimately move the field closer to new therapeutic strategies for patients.”

Roughly 150 million people worldwide will suffer from Alzheimer’s by 2050, making it the most common cause of dementia in the world. Despite this, scientists are still at a loss as to what exactly causes it.

Dhindsa’s research is part of a new range of theories that certain viral infections may trigger Alzheimer’s. His team will take a two-fold approach. First, they will analyze the medical records of more than a million individuals looking for patterns. Second, they will analyze viral DNA in stem cell-derived brain cells to see how the infections could contribute to neurological decay. The scale of the genomic data gathering is unprecedented and may highlight a link that traditional studies have missed.

Also joining the project are Dr. Caleb Lareau of Memorial Sloan Kettering Cancer Center and Dr. Artem Babaian of the University of Toronto. Should a link be found, it would open the door to using anti-virals to prevent or treat Alzheimer’s.
