Biography

Currently I'm a graduate student of School of Artificial Intelligence in Nanjing University and a member of LAMDA Group, which is led by Prof. Zhi-Hua Zhou.

I received my B.Sc. degree from College of Computer Science & Technology, Nanjing University of Aeronautics and Astronautics in June 2023 (GPA ranked 1 / 120). In the same year, I was admitted to study for a M.Sc. degree in Nanjing University, under the supervision of Assistant Researcher Han-Jia Ye without entrance examination.

Research Interests

My research interests include Machine Learning and Data Mining. Currently, I focus on Multimodal Large Language Models and Continual Learning.
