Research Area

Digital Health

We are an interdisciplinary team with an aim to empower providers, consumers, and clinical researchers. We create prognostic biomarkers by applying clinically explainable AI on advanced sensing technology, explore use cases by co-innovating with our partners, and design services through pilots that eventually turn into groundbreaking commercial, consumer-grade products that are used every day. Our work has been internationally recognized with 60+ peer reviewed publications and 10 design awards.
