I work in two research areas: Wireless and Health.

Wireless: My research interests span both theory and experimental designs for next-generation wireless. Several new graduate student positions are available for Fall 2025. My current research focus are as follows.

• Joint Communications and Imaging: See 4D100 and OneDegree for recent and ongoing work on developing foundations for high-resolution RF imaging at the city-scale. We are working on theoretical bounds, practical algorithms, novel hardware designs, and experimental validation.
• Learning-based Wireless Design: See ETHOS, RFDataFactory, LARA and 3DML for ongoing projects that cover algorithm design, open-source datasets, and deployed validation frameworks.
• Open-source Research Platforms: See RENEW for recent work and WARP for our past work. We just started a major new project – Houdini.

Health: My interest in health is at the intersection of machine learning, behavioral sciences, and medicine. We commonly use modern machine learning methods with a focused effort to improve healthcare outcomes. I founded and lead the Rice Digital Health Initiative. Rice is located across the world’s biggest medical center, Texas Medical Center, and it gives us a major advantage to conduct high-impact research. In my Scalable Health Labs. we are developing methods to uncover behavior-biology causal pathways, speech and vision AI for health and conducting many novel prospective trials.

In addition to ongoing research directions in mental health and diabetes, we have new projects in cardiology, Parkinson’s, and DBS-based interventions for bipolar disorder. Several new positions are available in the broad area of AI for health starting Fall 2025.

• I am the Rice lead on NSF Engineering Research Center, PATHS-UP that is developing cost-effective personalized technologies for under-served populations.
• Several recently-funded projects are in the startup phase, please write to me to learn more.

Translation: My research has led to four commercial spinoffs – one in wireless and three in healthcare. Most recently, two of our patents were licensed to develop a new medical device.

Graduate Students: We have several openings for graduate students. Please apply to Rice ECE. There is no application fee and GRE is optional.

Undergraduate Students: Undergraduate researchers are welcome in our labs. You can either for VIP credit in the ECE department – ELEC 491, Wearables Section 905 or RENEW Wireless, Section 907. Independent research is also welcome. We will also have many openings for summer internships.

Awards: Fellow of IEEE, ACM, and National Academy of Inventors, 2017 IEEE Jack Neubauer Memorial Award, 2018 IEEE Advances in Communications Award, 2019 and 2021 ACM Sigmobile Test-of-time Awards, 2019 ACM MobiCom Community Contributions Award, and 2023 ICC Best Paper Award.
