About me

I am a Research Scientist at Spotify in Boston. Before that, I completed my PhD in Computer Science, at Brown University, where I was fortunate to be advised by Jeff Huang, and I was a part of the Human-Computer Interaction research group. My research interests are in human-computer interaction and personal informatics with a special focus on sleep-tracking and self-experiments.

Updates

December 2020: The Self-E paper (the last chapter of my thesis!) was accepted to CHI 2021.
July 2020: I started as a Research Scientist at Spotify.
May 24, 2020: I graduated from my PhD.
April 9, 2020: I defended my thesis!

Research Projects

Self-E: a self-experimentation app that helps users optimize various aspects of their lives.
SleepBandits (a.k.a. SleepCoacher 2.0): a self-experimentation app that helps users optimize their sleep.
