Fan Zhang

Assistant Professor


My research focuses on solving security problems in real-world systems with cryptography. In particular, I’m interested in decentralized systems such as blockchains, anonymous communication, and trusted execution environments (TEEs). 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. In my separate capacity, I’m a faculty advisor at Chainlink Labs.
