I am currently a final-year Ph.D student in Department of Artificial Intelligence, School of Informatics, Xiamen University, advised by Prof. Rongrong Ji and Prof. Xiaoshuai Sun. I am actively looking for job opportunities (industry / faculty / postdoc), please feel free to contact me via email.
My recent research interests are in Multimodal Large Language Models (MLLMs) and Multimodal Generation.
