About
I am a joint Postdoctoral Researcher at the University of Maryland, College Park and Georgetown University under the guidance of Professor Jonathan Katz and Professor Justin Thaler. I recently received my PhD in Computer Science from Purdue University and was 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 was a Graduate Fellow during the Summer of 2019 at the Reichman University (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).
