I’m a Ph.D. candidate at the University of Maryland, College Park. I am advised by Prof. Rachel Rudinger.

I obtained my B.S. in Computer Science from the University of California, San Diego with Summa Cum Laude (GPA: 3.987/4.0) in 2019.

Full CV is available upon request.

Research Interests

My research aims to understand and mitigate the problems of bias and fairness in NLP models. My current research projects typically involve the empirical evaluations of large language models and algorithm designs to enhance fairness in natural language understanding and generation.
