Hi! I am a fifth year graduate student in the Computer Science department at the University of Texas, Austin. My advisor is Brent Waters. Before joining UT Austin, I completed my undergrad at Indian Institute of Technology, Kanpur.

I am interested in the theoretical aspects of Cryptography.

I spent the summer of 2013 as an intern at Microsoft Research, India working with Vipul Goyal .
