About Me

I am currently a Research Fellow at MMLab@NTU, working with Prof. Xingang Pan. I received my Ph.D. in June 2024 from the University of Science and Technology of China (USTC).

I am deeply grateful to Dr. Dongdong Chen for his continuous guidance and support throughout my academic journey. During my Ph.D., I was also fortunate to receive mentorship from Prof. Jing Liao and Dr. Gang Hua.

My research interests broadly lie in Computer Vision, and Generative AI, with a particular focus on image and video synthesis and editing. Feel free to email me for collaboration or academic discussion.
