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 health tech co. lands NIH grant for AI cancer prediction tool

fresh funding

Houston-based CellChorus and Stanford Medicine were recently awarded a Phase I Small Business Innovation Research grant for the company's AI platform to test how certain cancer patients will respond to therapies.

The funding comes from the National Cancer Institute of the National Institutes of Health. According to a filing, the grant totaled just under $400,000.

CellChorus, which spun out from the University of Houston’s Technology Bridge, has developed TIMING (Time-lapse Imaging Microscopy In Nanowell Grids), which analyzes the behavior of thousands of individual immune cells over time and can identify early indicators of treatment success or failure.

The company will work with Stanford's Dr. David Miklos and Dr. Saurabh Dahiya, who have built the Bone Marrow Transplantation and Cell Therapy Biobank. The biobank manages and stores biological samples from patients treated at their clinic and in clinical trials.

"Predicting which patients will achieve durable responses after CAR-T therapy remains one of the most important challenges in the field,” Miklos said in a news release. “We aim to uncover functional cellular signatures that can guide treatment decisions and improve patient outcomes.”

The project will specifically profile cells from patients with relapsed/refractory large B-cell lymphoma (r/rLBCL). According to CellChorus, only about half of r/rLBCL patients who receive CAR-T therapy "achieve a durable, long-term remission." Others do not respond to therapy or experience relapse.

“The sooner we know whether a cancer therapy is working, the better. To maximize patient benefit, we need technology that can provide a robust and early prediction of response to therapy. The technology needs to be scalable, cost-efficient, and capable of rapid turnaround times,” Rebecca Berdeaux, chief scientific officer of CellChorus, added in the release. “We are excited to work with Drs. David Miklos and Saurabh Dahiya and their colleagues on this very important project.”

CellChorus has previously received SBIR grants from federal agencies, including a $2.5 million award in 2024 from its National Center for Advancing Translational Sciences (NCATS) and a $2.3 million SBIR Fast-Track award from the National Institute of General Medical Sciences in 2023.

Houston museum showcases America's founding documents in rare exhibit

Experience History

As the United States prepares to celebrate its 250th birthday, Houstonians have a chance to see rare documents from the founding of the nation. Freedom Plane National Tour: Documents That Forged a Nation, presented by the National Archives Foundation, will be on display at the Houston Museum of Natural Science through Monday, May 25.

The collection includes a rare engraving of the original Declaration of Independence; official Oaths of Allegiance signed by George Washington, Aaron Burr, and Alexander Hamilton; a draft of the Bill of Rights; the Treaty of Paris, the documented that recognized America's independence from Great Britain; and the tally of votes approving the Constitution.

The National Archives specifically chose Houston as one of only eight cities in the country to host the exhibit as a means to help the documents reach a wider audience outside of the main hub of semiquincentennial events in New England and the Washington, D.C. area.

"One of the things we decided when we put the tour together because we wanted to be off the East Coast," said Patrick Madden, CEO of the National Archives Foundation, who was onsite for the exhibit's opening in Houston. "There's a lot of 250th celebration stuff happening in the original 13 colonies. How do we get it to major markets where larger numbers of people can see it? So in the case of Houston, obviously, [is a] major market in this part of the country, but also we've partnered with the museum twice before with National Archives exhibits, so we knew that they would be up to the task of handling the exhibit and the crowds."

The star of the collection is a rare engraving of the original Declaration of Independence. Secretary of State and future president John Quincy Adams commissioned 200 exact replicas of the document from engraver William J. Stone in 1823. Less than 50 now remain. Madden joyfully pointed out that there are errors in this document, a potent reminder that the men who forged a nation made mistakes.

"There's a couple of typos in it where they had to make corrections," said Madden. "So even the founders, you know, they're all human. That resonates because here these people are making this move against the most powerful nation in the world and putting their lives on the line for a country based on ideas."

Other impressive parts of the collection include official Oaths of Allegiance signed by George Washington, Aaron Burr, and Alexander Hamilton, as well as one of the drafts of the Bill of Rights. Many states would not ratify the Constitution until certain rights were included in the document, leading to Washington going on a national tour assuring state leaders enshrining protections was first on the list. The draft copy on display specifically shows the First Amendment in progress.

Houston is the fourth stop on the exhibition's tour, which will take the documents to Denver, Miami, Dearborn, and Seattle through the summer. Freedom Plane is just one part of a larger patriotic celebration at the HMNS, which includes a film series celebrating American science and culture and general Americana decoration throughout the main hall.

Admission to Freedom Plane is free to the public, but separate from general admission to the museum. Space is limited, and passes are available on a first-come, first-serve basis. Non-members should expect long waits or the possibility that the day's passes are sold out. Only museum members can reserve passes for specific times. Flash photography is prohibited due to the fragile nature of the documents.

Houston quantum energy chip startup emerges from stealth with $12M round

seed funding

Houston-based Casimir has emerged from stealth with a $12 million seed round to commercialize its quantum energy chip.

The round was led by Austin-based Scout Ventures. Lavrock Ventures, Cottonwood Technology, Capital Factory, American Deep Tech, and Tim Draper of Draper Associates also participated in the round. The oversubscribed round exceeded the company’s original $8 million target, according to a news release.

Casimir’s semiconductor chips can generate power from quantum vacuum fields without the need for batteries or charging. The company plans to commercialize its first-generation MicroSparc chip by 2028.

The MicroSparc chip measures 5 millimeters by 5 millimeters and is designed to produce 1.5 volts at 25 microamps, comparable to a small rechargeable battery, without degradation and no replacement cycle.

“Casimir represents exactly the kind of breakthrough dual-use technology Scout Ventures was built to back,” Brad Harrison, founder and managing partner at Scout Ventures, said in the release. “This is based on 100 years of science and we’re finally approaching a commercial product … We’re proud to lead this round and support Casimir’s journey from applied science to deployed technology.”

Casimir says it aims to scale its technology across the ”full power spectrum,” including large-scale energy systems that can power homes, commercial infrastructures and electric vehicles.

Casimir's scientific work has been supported by DARPA-funded nanofabrication research and its technology was incubated at the Limitless Space Institute (LSI). LSI is a nonprofit that works to innovate interstellar travel and was founded by Kam Ghaffarian. Technology investor and serial entrepreneur Ghaffarian has been behind companies like X-energy, Intuitive Machines, Axiom Space and Quantum Space.

Harold “Sonny” White, founder and CEO of Casimir, believes the technology can power devices for years without replacements.

“Millions of devices will operate for years without a battery ever needing to be replaced or recharged because we have engineered a customized Casimir cavity into hardware capable of producing persistent electrical power,” White added in the release. “I spent nearly two decades at NASA studying how we power humanity’s future. That work led me to the Casimir effect and the quantum vacuum, where new tools have allowed us to build on a century of scientific knowledge and bring abundant power to the world.”
