About

I am a computer science Ph.D. candidate at Princeton, where I am advised by Prof. Mark Zhandry. Previously, I received my B.S. in mathematics from MIT, where I had Prof. Erik Demaine as a research advisor.

I am broadly interested in the theory of computation, with a focus on the foundations of cryptography.

Visits

In summer 2018, I worked with Dr. Tancrède Lepoint as an intern at SRI International in New York City. I spent Jan–Feb 2019 visiting Prof. Alon Rosen and Prof. Elette Boyle at the IDC Herzliya FACT Center.

In summer 2019, I worked with Dr. Pratyay Mukherjee, Dr. Daniel Masny, and Dr. Yilei Chen as an intern at Visa Research in Palo Alto.

I am currently a visiting graduate student at UC Berkeley hosted by Prof. Alessandro Chiesa and a (remote) intern at NTT Research.
