About me

I am a computer science Ph.D. student at UCSD where I am fortunate to be advised by Prof. Mihir Bellare. I am broadly interested in cryptography and provable security.

At UCSD, I am part of the CryptoSec and Theory groups. Previously, I spent two years at Microsoft working as a software engineer after completing my B.E in Computer Science and Engineering at BIT, Mesra.
