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.

Italian aerospace company sets up first U.S. office at Houston Spaceport

welcome to houston

Como, Italy-based aerospace company Involve Space recently made the Houston Spaceport the site of its first U.S. office.

Involve Space develops high-altitude balloon platforms for Earth observation, scientific research and hardware testing. The balloons carry instruments into the stratosphere (a layer of the upper atmosphere) to collect images and data, conduct experiments and test technology.

The company plans to launch its first commercial missions from Houston by the end of this year, according to a news release.

“Houston is the global center of aerospace, and our presence at Houston Spaceport strengthens our international growth trajectory,” Jonathan Polotto, founder and CEO of Involve Space, said in the release.

Founded in 2021, Involve Space incorporates aerospace hardware, AI and geospatial tools into its offerings. Its proprietary CLEAR platform uses conversational AI to help customers interpret data and support decision-making.

Located at Ellington Airport, the Houston Spaceport provides a base for Involve Space’s North American operations, including business development and partnerships with aerospace companies and researchers.

Other tenants at the Houston Spaceport include NASA, Axiom Space, Venus Aerospace and Intuitive Machines.

Involve Space’s relationship with the Houston Spaceport began in January 2025, when it conducted its first U.S. pilot launch. During the five-hour mission, the balloon reached an altitude of about 85,000 feet and traveled about 250 miles across Texas.

One of Involve Space’s first U.S. customers is Houston-based Rhodium Scientific, a space biotech company. Polotto and Rhodium Scientific founder and CEO Olivia Gamez Holzhaus signed a deal to conduct biotech experiments aboard Involve Space’s stratospheric balloon platforms before planned missions to orbit.

“The presence of innovative platforms like those developed by Involve strengthens the Spaceport’s role as a site for testing, validating, and deploying advanced technologies between aeronautics and space,” Jim Szczesniak, director of aviation for Houston Airports, added in the release.

UH lands $3M grant to expand opioid overdose training

Overdose Response

The University of Houston has received a $3 million federal grant to expand its potentially life-saving overdose response training program.

The grant will support the Houston Health Department’s FRONTLINES program that trains first responders in Harris and Fort Bend counties to recognize opioid overdoses and administer the drug naloxone, which can counter the effects of an opioid overdose. The four-year grant comes from the Substance Abuse and Mental Health Services Administration within the Department of Health and Human Services, and it builds on eight years of work at UH, according to a release from the university.

As part of the expansion, UH medical, social work and psychology students will now also be able to take part in FRONTLINES’ overdose-response training. Some of the students will also be selected to help train community members, ultimately passing along the life-saving skills throughout Houston.

FRONTLINES is a collaboration with the City of Houston, the Fertitta College of Medicine, Baylor College of Medicine and the Houston Recovery Center. It was co-founded by Dr. James Bray, chair of the Department of Behavioral and Social Sciences at the University of Houston’s Tilman J. Fertitta Family College of Medicine, in 2018.

“When someone experiencing an opioid overdose is reached in time, naloxone can save their life,” Bray said in a news release. “We’ve seen the impact this training can have in Houston, and now we have an opportunity to extend that reach across Harris and Fort Bend counties, putting lifesaving knowledge and tools into the hands of more first responders.”

In 2024, around 450 residents of Harris County died from opioid overdoses, according to a Texas Department of State Health Services report. The report found that fentanyl was involved in about three-quarters of the deaths.

In 2025, UH also received a $2.6 million gift from the estate of Dr. William A. Gibson to expand its opioid research and develop a vaccine to help block fentanyl's effectiveness in entering the brain. The vaccine research is part of the Michael C. Gibson Addiction Research Program led by UH professor of psychology Therese Kosten and founding member of the UH Drug Discovery Institute Colin Haile.

Texas public libraries drive billions in economic impact, report finds

Beyond the Stacks

A new statewide study examining the economic impacts of public libraries has revealed they have generated over $3.8 billion in value to local communities — a return of $4.74 for every $1 invested.

The report, "Beyond the Stacks: Measuring the Economic and Community Value of Texas Public Libraries" was conducted by third-party consultancy JBK Economics Group in partnership with the Texas Library Association. About 300 of the total 513 public libraries in Texas participated in a survey for the report.

A major finding from the survey revealed that public libraries create billions in economic value for the communities they serve at a fraction of what it costs to pay employee wages and benefits, operating expenditures, and capital expenditures. About 11,200 jobs were directly and indirectly supported by public libraries, the report found.

The report found its $4.74 to $1 ratio by adding up the total value of the services provided by these institutions (an estimated $2.48 billion), and comparing it to total expenditures ($808.6 million).

"Public libraries had about the same economic footprint as the Texas motion picture and sound recording industry ($2.9 billion in Gross Domestic Product in 2024) or the Texas paper manufacturing industry ($4.0 billion in Gross Domestic Product in 2024)," the report said.

Many Houstonians are already familiar with Houston Public Library's expansive catalog and programming, but there are many more services the library provides that might fly under the radar. A few examples include access to subscription-based research databases and news outlets, and the Library of Things, a collection of cookware and bake ware, musical instruments, craft kits, and other tools or activity materials that are available for cardholders to borrow. Individual branches also provide free Wi-Fi, computer access, and meeting spaces.

Houston-area residents also have access to services at several other local libraries depending on their address, such as the Harris County Public Library, Montgomery County Memorial Library System, or Fort Bend County Libraries, just to name a few.

These are additional services and partnerships that Texas public libraries commonly provide, per the survey results:

  • 93 percent provide voter registration and/or serve as voting locations
  • 84 percent provide partnerships with local social services agencies
  • 82 percent provide job application assistance
  • 68 percent facilitate applications for government benefits
  • 38 percent provide on-site social services
  • 30 percent provide telehealth rooms and/or resources
"Public libraries are practical, welcoming and rooted in the communities they serve — they are unmistakably Texan," said Texas Library Association executive director Shirley Robinson in a press release. "This study puts a dollar value on the opportunities libraries create every day. Whether someone visits a library to apply for a job, access the internet, learn a new skill or simply find a new favorite book, those services create real value for Texans and their communities."
