My research interests mainly focus on Software Engineering for/with AI, Trustworthy AI, and Data Science. I received WWW 2019 Best Full Paper Award, ACM SIGSOFT Distinguished Paper Award, ASE 2023 Distinguished PC Member Award, and ICSE 2025 Distinguished Reviewer Award.

📍 I am recruiting PhD, Master’s, and undergraduate students. I welcome self-motivated students with strong backgrounds in AI and Software Engineering. If you are interested in joining my group, please send me your CV via email. 我正在招收线上/线下科研实习生，欢迎有兴趣的同学联系我。

Before joining Tsinghua University, I was a Research Fellow at Nanyang Technological University, working with Prof. Yang Liu. Prior to that, I was a Research Fellow at University College London, working with Prof. Mark Harman and Prof. Federica Sarro.

I received my Ph.D. from Peking University (PKU) in 2021, and was fortunate to be advised by Prof. Hong Mei and Prof. Xuanzhe Liu. My Ph.D dissertation won the Outstanding Doctoral Dissertation Award of China Computer Federation. I received my B.S. in Computer Science and B.A. in Economics from PKU in 2016.
