Incoming M.S. Student

Southeast University Fall 2027

I will join Southeast University as a master's student in Fall 2027, where I will be advised by Prof. Xiu-Shen Wei. I am currently completing my undergraduate studies at Guangdong University of Technology.

My research focuses on robust multimodal learning, particularly how vision-language models adapt and generalize under distribution shifts. I am interested in understanding not only what models can achieve, but also why they fail and what makes their behavior reliable.
