Fan Zhang

Assistant Professor


I’m an Assistant Professor in Computer Science at Yale University. I received my Ph.D. in Computer Science from Cornell University, advised by Prof. Ari Juels. I received my bachelor’s degree from Tsinghua University. I’m also a faculty advisor at Chainlink Labs.

My research focuses on the security, privacy and scalability of decentralized systems, in particular those enabled by blockchains and trusted execution environments (TEEs). To learn more, you can check out my research page and publications.
