About Me

I am a graduate student pursuing a PhD's degree in the Department of Computer Science at the University of Wisconsin-Madison. I am advised by Prof. Kangwook Lee. My current research interests include large language models and machine learning fairness. I received my Master's degree in Statistics from UW-Madison in 2020, where I was advised by Prof. Miaoyan Wang. Before joining UW-Madison, I completed my Bachelor's degree in Statistics from the School of Mathematical Sciences at Nankai University in 2019.
