I am a Ph.D. student in Computer Science at Beihang University (BUAA),
where I am advised by Prof. Di Huang.

My research interests are in computer vision and generative models, especially diffusion-based image and video generation.

I received my M.S. from Beihang University in 2023 and my B.E. from Tianjin University in 2020. I have interned at Shanghai AI Laboratory, Alibaba TongYi Lab, and Alibaba DAMO Academy.

Open to Opportunities:I expect to graduate in December 2026 and am currently on the job market for research positions in academia and industry, particularly in image/video generation and world models.
