picture1I am a fourth-year Ph.D. student in the Computer Science Department at Carnegie Mellon University, fortunately advised by Prof. Elaine Shi. Prior to this, I was a master student and research assistant advised by Prof. Xin Li at Johns Hopkins University. Previously I got my bachelor’s degree in Information and Computing Science School of Mathematical Sciences Department at Fudan University

Research Interest: I’m interested in the intersection of theoretical cryptography and game theory, as well as related areas in theoretical Computer Science.

I’m currently co-organizing the crypto seminar at CMU. Please contact me if you want to give a talk! See more information on our website.

My CV is available here.
