About Me

Hi! I am a first-year PhD student at MMLab, The Chinese University of Hong Kong, supervised by Prof. Hongsheng Li and Prof. Xiaogang Wang. Prior to this, I received my Master's degree from the AAIS, Peking University in 2025, where I am a member of Lanco Lab, Institute of Computational Linguistics (ICL), supervised by Prof. Xu Sun. I obtained my Bachelor's degree from the School of Data Science, Fudan University in 2022.

My research interests lie in multimodal learning, like visual understanding, visual representation, image captioning and so on. I also have interest in some multimodal generation tasks, like diffusion models, and their applications in text-guided generation.
