About Me

I joined Computer Science & Engineering (CSE) Department at Washington University in St. Louis (WashU) in 2024 as an Assistant Professor. I received my Ph.D. degree in Computer Science Department, UIUC, advised by Prof. Jiawei Han. After that, I visited UW as a researcher and worked with Prof. Hanna Hajishirzi. Prior to UIUC, I received my Bachelor Degree in Electronic Engineering in Tsinghua University in 2018. My research interest broadly lies in the intersection of natural language processing and machine learning, and I am especially interested in understanding the properties of language models as well as improving their trustworthiness and efficiency.

I am looking for PhD students and interns! If you are interested in working with me, please fill in this form. Check out this page for more details!
