Hi! I am an Assistant Professor at Columbia University, Department of Biomedical Informatics and a Visiting Faculty Researcher at Google Research. I am also affiliated with the Department of Computer Science and the Data Science Institute at Columbia. I focus on applying human-computer interaction (HCI), artificial intelligence (AI) methods for health applications.

I lead the SEA (Sense, Empower, and Augment) Lab. We aim to leverage everyday data and build better human-centered methods, devices, and systems to sense, empower, and augment human health and well-being.
