I’m an Assistant Professor in Computer Science at Duke University. My research focuses on making real-world decentralized systems more secure using cryptography and trusted execution environments (TEEs).
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 also 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.
I'm always looking for motivated students! Send me an email if you are interested in working with me.
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 Crier (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
