Biography

I am a Ph.D. at the Multimedia Laboratory (MMLab) of The Chinese University of Hong Kong (CUHK), fortunate to be supervised by Prof. Hongsheng Li. I also work closely with Prof. Xihui Liu. I completed my doctorate in 2025.

My research is driven by a passion for Artificial General Intelligence (AGI) with a focus on visual understanding and generation. I am dedicated to developing integrated systems capable of perceiving, understanding, and generating visual content by leveraging advanced techniques with Multimodal Large Language Models.

Previously, I was a visiting scholar at MIT CSAIL, advised by Prof. Dina Katabi. I obtained my B.Eng. degree from Shanghai Jiao Tong University, where I was ranked 1st/157 and advised by Prof. Bingbing Ni.
