About Me

PhD Candidate at Cornell Tech working in the small data lab and advised by Deborah Estrin, Nicki Dell and Tanzeem Choudhury. I am also a doctoral fellow at DLI. In my research, I combine computer science and behavioral sciences to design, develop and evaluate tools for target users in the US and in ''developing'' countries.

Broadly, my research interests are in the field of human-computer interaction (HCI), information and communication technologies for development (ICTD), and behavioral sciences.
