Yixuan Ren

I am a final-year Ph.D. student in the Department of Computer Science at the University of Maryland, College Park, advised by Prof. Abhinav Shrivastava. I also received my M.S. degree here. Prior to that, I obtained my B.E. degree from Tsinghua University.

My research lies in the intersection of Computer Vision and Generative AI, with focuses on image and video synthesis and editing. I am broadly interested in various generative modeling techniques and visual tokenization for generative purposes.

I am actively seeking full-time opportunities starting early or mid 2026. If you think I might be a good fit, please don't hesitate to reach out!
