Hi! I am a Ph.D. student studying computer science at University of Pennsylvania, where I'm fortunate to be advised by Prof. Sebastian Angel and Prof. Tal Rabin. I'm broadly interested in cryptography, security and privacy, and computer systems. I'm generously supported by a Microsoft Research PhD Fellowship.
Prior to UPenn, I completed my B.S. in 2020 at Peking University, where I graduated from Turing Class honors program.
