Hi! I am a Ph.D. student studying computer science at University of Pennsylvania, where I'm fortunate to be advised by Sebastian Angel and 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.

In summer 2023, I worked as an associate at J.P. Morgan, hosted by Antigoni Polychroniadou. In spring 2022, I visited Yuval Ishai at Technion. In summer 2020, I worked as a security engineer at Alibaba Gemini Lab, hosted by Cheng Hong. In summer 2019, I did an internship via Summer@EPFL program, hosted by Jean-Pierre Hubaux.
