My Background

I am an Assistant Professor in the Department of Computer Science at the University of Toronto and an Affiliate Scientist at KITE. I run the Computational Health and Interaction (CHAI) lab, which leverages ubiquitous technologies like smartphones and wearables to address problems related to people’s health. Using sensor data collected from momentary assessments or passive recordings, I employ signal processing and machine learning to generate digital biomarkers related to a person's physiology, context, and behavior. My work also spans other topics at the intersection of ubiquitous computing and human-computer interaction such as mobile interaction, user-centered design, and novel sensing techniques.

Before joining the University of Toronto, I completed a joint postdoctoral role under Larsson Omberg and Anind Dey, where I split my time between the Sage Bionetworks and the School of Computer Science and Engineering at the University of Washington. I completed my PhD at the University of Washington under the supervision of Shwetak Patel and Jacob O. Wobbrock. I completed my undergraduate studies at Duke University with a double major in Electrical and Computer Engineering and Computer Science. During that time, I conducted research under Romit Roy Choudhury.
