I am a researcher in the Core Data Science team at Facebook. My recent work focuses on understanding and modeling users, their interests, and their interactions at individual and collective levels, with the goal of improving their Facebook experience. Prior to joining Facebook I was a researcher at Technicolor Labs and a Post-doc at University of British Columbia. I received my Ph.D. in Computer Science from Rutgers University. My past work studied various aspects of social influence, social recommendations, and the interplay between inference and privacy in social networks.
