About:

I am a Ph.D. student in Information Science at the University of Pittsburgh under the guidance of Dr. James Joshi as part of the LERSAIS Lab. I am a student member of IEEE, IEEE Computer Society, and AAAS. Prior to joining the Ph.D. program, I received my M.S. in Information Science from the University of Pittsburgh and my B.E. in Information Security from Shanghai Jiao Tong University.

My research focus is on Privacy-Preserving Machine Learning (PPML), Quantum Machine Learning (QML), and broadly game-theoretic approaches to security and privacy of ML.

A current version of my CV can be downloaded here (last updated Aug. 2026).

Research:

My current project concerns Machine Unlearning (MU) and its related privacy and security attacks and defenses. This project is currently funded by NSF and Cisco Research. I'm also exploring topics on Quantum Machine Learning (QML) and its security & privacy issues, currently funded by Cisco Research.
