Postdoctoral Scholar

Stanford University

I am a Postdoctoral Scholar in the Computer Science department at Stanford University, where I am a member of the HCI group and supervised by James Landay. I received my PhD in Information Science from Cornell University, where I was advised by Tanzeem Choudhury.

My research spans the areas of Human-Computer Interaction, Ubiquitous Computing, and Mobile Health. Much of my work focuses on designing, developing and evaluating unobtrusive mobile applications for health and well-being. I design subtle interventions that change how users perceive interoceptive (e.g., heart rate), behavioral (e.g., voice) or environmental cues (e.g., color of objects) for emotion regulation or behavior change.
