About Me
I’m an incoming Assistant Professor in Computer Science at Duke University starting 2021 Fall. I’m currently a security researcher at Chainlink Labs. My research primarily focuses on security/privacy/scalability problems in decentralized systems, especially those enabled by blockchain protocols 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.
(Full bio here.)
I devise novel cryptographic protocols, build systems that work for
a reason, and reveal interesting facts via empirical measurements.
Here are some projects I’ve been working on:
I’m always looking for motivated students! Send me an email if you are interested.
