I’m looking for PhD students to work together! If you are interested in working with me as a PhD student, please apply to the CSE graduate program during the regular admissions cycle. You are strongly encouraged to email me with your CV to let me know you applied (or will apply). 

Research Interest: I’m interested in the intersection of theoretical cryptography and game theory, as well as related areas in Theoretical Computer Science. My work mainly focuses on combining cryptography and game theory to design incentive-compatible and provably secure decentralized protocols. I’m also interested in error correction codes and their application in cryptographic primitives.

Bio

I obtained my Ph.D. at Carnegie Mellon University, fortunately advised by Prof. Elaine Shi. Prior to this, I was a master’s 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 from the School of Mathematical Sciences at Fudan University. 

Here is my CV.
