About

I am advised by Prof. David Cash. Prior to joining UChicago, I was a PhD student at Rutgers University until 2018.

I completed my B.Tech in CSE from IIIT-Delhi in 2016, where I was advised by Prof. Donghoon Chang and Prof. Somitra Sanadhya. I mostly worked on Cryptanalysis under their esteemed guidance.

My research interests broadly include cryptography and related areas of security and theoretical computer science.
