Biography

I am a third-year joint Ph.D. student at The Hong Kong Polytechnic University (PolyU), supervised by Prof. Jiannong Cao (Chair Professor, IEEE Fellow, CCF Fellow), and Southern University of Science and Technology (SUSTech), supervised by Prof. Yuhui Shi (Chair Professor, IEEE Fellow). During my Ph.D. studies, I have closely collaborated with Dr. Pichao Wang from Amazon. I received my B.E. in Computer Science and Technology from SUSTech in 2021. For further details, view my CV.

My research primarily focuses on Text-to-Video Generation and Computer Vision, with a particular emphasis on achieving precise alignment between human instructions and generated video content.
