Working on Cryptography

Hi! Welcome to my homepage!

I am currently a postdoctoral researcher at Singapore Management University (SMU), hosted by Prof. Robert H. Deng and Haiyang Xue. Before joining SMU, I worked as a cryptography researcher at Ant Group (2022-2024) and completed my PhD at the Institute of Software, Chinese Academy of Sciences (2016-2022), advised by Prof. Zhenfeng Zhang.

I am interested in threshold cryptography, zero-knowledge proofs, multi-party computation, and fully homomorphic encryption.
