I am the Lawrence R. Quarles Professor of Engineering and Applied Science and a Professor in the Department of Systems and Information Engineering (opens in new tab) at the University of Virginia (opens in new tab). I am Associate Director of the Link Lab (opens in new tab) and direct the Sensing Systems for Health (S²He) Lab.

My research group creates mobile, wearable, and AI systems that understand human behavior and health in everyday life. We develop computational methods that combine multimodal sensing, machine learning, and AI to measure behavior and health outside the clinic and to build personalized, context-aware systems that can support people when and where they need it.

Our work spans digital health, behavioral interventions, and patient-clinician communication, with a focus on moving advances in sensing and AI from methodological development to applications that support health and well-being. I work closely with collaborators across engineering, behavioral science, medicine, and nursing to design and evaluate these technologies.
