I am a first-year PhD student in Computer Science at University of Chicago, advised by Prof. Kexin Pei and Prof. Shan Lu.

I received my M.S. degree at UIUC advised by Prof. Lingming Zhang in 2024. Prior to that, I obtained my B.S. degree from Huazhong University of Science and Technology in 2022, where I was advised by Prof. Ming Wen.

My research interests are software engineering, program analysis, program testing/repair.
