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.
