About Me
I am a Ph.D. candidate advised by Prof. Rafail Ostrovsky at UCLA. I am interested in solving practically relevant questions of cryptography.
Formerly, I was a Research Fellow at Microsoft Research (MSR) India, where I worked closely with Dr. Nishanth Chandran and Dr. Divya Gupta. Prior to that, I completed my M.Tech (Research) in Computer Science from Indian Institute of Science (IISc) under the supervision of Prof. Sanjit Chatterjee.
