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.
