Resource

In December 2023, I moved to Harbin Institute of Technology (HIT) as Associate Professor. In December 2019, I joined Southern University of Science and Technology (SUSTech) as Research Assistant Professor. In March 2019, I joined the University of Birmingham as Research Fellow. I obtained my PhD degree from School of Computer Science of the University of Birmingham under the supervision of Prof. Xin Yao (co-supervised by Dr. Leandro L. Minku). Previously, I received my BSc and MSc degrees from School of Mathematics of Harbin Institute of Technology.

Research Interests

My main research interests are machine learning and its applications to predictive software engineering. Currently, I am working on I am also working with evolutionary computation, deep learning, and their applications to (e.g.) image recognition and network privacy. I am OPEN novel and relevant research areas if you can convince me of their practical significance.

Openings: 正在招收2025年一志愿报考哈工大计算机的考研生！
We are opening to Master, PhD students and visiting students working on those topics who are good at coding and/or math.
