About Me

I am a Ph.D. candidate in the Department of Computer Science at Purdue University, advised by Prof. Xiangyu Zhang since 2021. Before that, I received my Bachelor’s degree in Computer Science and Technology from Huazhong University of Science and Technology in 2020.

My research focuses on building efficient and effective LLM agents for automated software development tasks such as code refactoring, software testing, and program repair, with the broader goal of improving software correctness, robustness, and trustworthiness.
