Fan Zhang

I am on the academic job market this year.

About

Fan Zhang is a Ph.D. candidate in Computer Science at Cornell University, advised by Prof. Ari Juels. His research interest is in building secure systems that empower and protect their users from insecure and centralized infrastructure, by leveraging cryptography, blockchains, and trusted execution environments (TEEs).

His Ph.D. thesis focuses on a principled composition of on-chain and off-chain components to enable provably secure, efficient, and decentralized systems. His works have been featured in Forbes, MIT Tech Review, IEEE Spectrum, CoinDesk, BitcoinMagazine, and numerous blockchain news outlets. Several of his works have been adopted by industry and deployed in the wild. He is a member of IC3 and a recipient of an IBM Ph.D. Fellowship for 2018-2020. Before joining Cornell, he received his Bachelor's degree from Tsinghua University.
