I am a professor in the School of Computer Science and Technology at the Beijing Institute of Technology. I was formerly a graduate student at the Software Engineering Institute, Peking University. I defended my PhD thesis in June 2008.

My research interests include deep learning based software engineering, in particular: deep learning based program generation; software refactoring; automatic program repair; software quality; machine learning based code complete; automatic construction of software engineering datasets. My work is funded in part by the National Natural Science Foundation of China, and the National Key Research and Development Program of China.

I am a recipient of the ACM Distinguished Paper Award in the 44^th International Conference on Software Engineering (ICSE 2022), the RE'2021 Best Research Paper Award (2021), IET Software Premium Award (2018), New Century Excellent Talents in University (2013), and Beijing Higher Education Young Elite Teacher (2013). I am also a distinguished member of China Computer Federation (中国计算机学会杰出会员)

I am always looking for self-motivated students to work with me. Contact me by eMail if you are interested in deep learning, software engineering, natural language processing, or data mining.
