about
- My research focuses on computer security and applied cryptography. In particular some of my current projects include verifiable and privacy-preserving computations, with applications to cloud computing security, leakage-abuse attacks on searchable encryption systems, private and scalable blockchains and cryptocurrencies, as well as building real-world privacy-preserving systems. My work is currently supported by NSF, Protocol Labs and JP Morgan.
- I am always looking for bright and self-motivated students that wish to do research on computer security and applied cryptography. Feel free to contact me if you are interested.
I am currently serving as the chair of PhD admissions at Yale Computer Science.
