About Me

I am a Ph.D. student in the EECS department at UC Berkeley advised by Professor Dawn Song. Before joining UC Berkeley, I received my bachelor’s degree from ACM Honors Class, Shanghai Jiao Tong University. I am a member of Berkeley Center for Responsible, Decentralized Intelligence (RDI), Initiative for Cryptocurrencies & Contracts Lab (IC3), and Berkeley Artificial Intelligence Research (BAIR) Lab.

  • Research Interest: I am broadly interested in computer security, systems, and machine learning, especially building systems that enable secure and privacy-preserving data processing or solve real-world security problems.


  • Jul 2023: Honored to be supported by the JP Morgan Chase PhD Fellowship 2023.
  • Nov 2022: “The practical use of differential privacy across the enterprise is within striking distance.” Check out our paper accepted to PETS 2022.
  • Oct 2022: Released CoLink, a project focusing on creating decentralized programming abstractions. Check out our talk at NIPS 2022 Workshop.
