I am a Computer Science Ph.D. candidate at Stony Brook University, advised by Prof. Aruna Balasubramanian working in the NetSys Lab.
My research interests include Mobile Systems, Sensing, and Accessibility. I work to make smartphone applications more accessible to users with disabilities. My research has been published at leading venues like MobiCom, CHI, SenSys, and UbiComp.
I am a recipient of the Paul Baran Young Scholars Celestini Prize India 2018 awarded by the Marconi Society for developing AirCognizer.
