About Me

I’m an Assistant Professor in Computer Science at Duke University. 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 recent projects and publications.

My research has led to direct industry adoption. Town Crier and DECO have been licensed to Chainlink (news, news). Ekiden is used in Oasis Labs’ products. In my separate capacity, I’m a security researcher at Chainlink Labs.

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.
