About

I am a PhD Candidate in my final year at Purdue University in the Computer Science department. I am extremely fortunate to be advised by Professor Jeremiah Blocki. My broad research interests are in Theoretical Cryptography, Efficient Proof/Argument Systems, and Coding Theory. I am a member of both the Cryptography Group and the Theory Group at Purdue. I am currently the President of the Computer Science Graduate Student Association at Purdue, and was one of the organizers of the Purdue Theoretical Computer Science Theory Seminar during Spring 2020.

I was a Graduate Fellow during the Summer of 2019 at the IDC Herzliya FACT Center under the guidence of Alon Rosen.

I received my M.Sc. in Computer Science from Purdue University in 2019. Prior to that, I received a B.S. in both Mathematics (Hons.) and Information & Computer Science (Hons.) from the University of California, Irvine, and graduated with Campuswide Honors from the Campuswide Honors Collegium (formerly known as the Campuswide Honors Program).
