Biography

Xian Liu is a third-year Ph.D. candidate at Multimedia Laboratory (MMLab), Department of Information Engineering in The Chinese University of Hong Kong. He is supervised by Prof. Dahua Lin and Prof. Ziwei Liu. He also worked closely with Prof. Xihui Liu. His research interests include computer vision and generative modeling, especially its applications in human generation, modeling, animation, video, and foundation models.

Before that, he received the Bachelor's degree at Zhejiang University in 2021, advised by Prof. Xiaowei Zhou.

I am always open to discussions and collaborations, feel free to drop me an email if you are interested in :)
