Hi, I'm a PhD student in the Computer Science Department at Carnegie Mellon University. I'm being advised by Giulia Fanti and Elaine Shi.

Plan to graduate in 2025 and looking for a job :)

Research Interests

I am interested in {efficiency, safety, privacy} x {information retrieval, data aggregation, AI/ML, etc}.

I design algorithms and do implementations.


I received my B.S. in Computer Science from Peking University.
