About Me

I am a PhD student in the Department of Computer Science at University of Virginia. Currently, I work on algorithmic fairness, privacy and security of machine learning, and natural language processing. My advisor is Prof. Yuan Tian. Previously, I obtained my B.Eng. degree from Beijing University of Posts and Telecommunications in 2017.
