About Me

I’m an Assistant Professor at Yale CS. My research aims to make real-world systems secure, verifiable, and fair by applying and advancing cryptographic techniques. Recently, I’m passionate about blockchains systems and their applications (e.g., DeFi), identity and credentials, anonymity networks, etc. I received my Ph.D. in Computer Science from Cornell University, advised by Prof. Ari Juels, and my bachelor’s degree from Tsinghua University.

I run the Decentralized Systems Group at Yale CS. Check out the group page and the publication page for more inforamation.

I’m also affiliated with IC3, Center for Distributed Confidential Computing (CDCC) and Center for Algorithms, Data, and Market Design at Yale (CADMY).

At Yale, I teach Intro to Blockchain and Real-World Cryptography.
