I am currently a Lecturer in School of Artificial Intelligence and Information Technology of Nanjing University of Chinese Medicine. I obtained my Ph.D. degree in Computer Science in June 2024 from School of Artificial Intelligence of Nanjing University, where I was very fortunate to be advised by Prof. Zhi-Hua Zhou. Before that, I got my B.Eng. degree in Information Science in June 2019 from Chu Kochen Honors College of Zhejiang University.

My research interests include machine learning and multi-objective optimization. Currently, I mainly focus on ensemble learning methods, and Artificial Intelligence in TCM Clinical Data Mining.
