About Me

I am an Associate Professor in the School of Computer Science and Engineering at Southeast University. I was a Zhishan Postdoctoral Researcher working with Prof. Xin Geng at Southeast University. I got my Ph. D. degree from Nanjing University in 2020, supervised by Prof. Yang Gao. In 2011 and 2015, I obtained my bachelor degree and master degree (supervised by Prof. Mingwu Ren) from Nanjing Normal University and Nanjing University of Science and Technology. From August 2018 to August 2019, I was a visiting student at University of Wollongong, supervised by Prof. Lei Wang.

Research Interests

My research interests include Computer Vision (CV) and Pattern Recogintion (PR).

Currently, I mainly focus on the CV topics including Person Re-identification, Anomaly Detection and Semantic Segmentation, etc.
For PR, I am interested in Domain Generalization (DG) and Vision-Language Model (VLM).
