About Me

I’m an Assistant Professor and a security researcher. 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:

• Decentralized identity: CanDID (Oakland'21)
• Order Fairness in Byzantine Fault Tolerance: Aequitas (Crypto'20)
• Smart contract oracles: DECO (CCS'20), Town Cirer (CCS'16)
• Privacy-preserving protocols for blockchains: CHURP (CCS'19), Ekiden (EuroSP'19), Solidus (CCS'17)
• Trusted hardware and blockchain hybridization: Proof of useful work (Usenix'17), Sealed-glass proofs (EuroSP'17), Tesseract (CCS'19)
• Stealing ML models: Usenix'16
• and more…
• Some of them appeared in the news: Media coverage
