About Me

I’m a PhD student at Zhejiang University under the supervision of Prof. Jun Xiao（Sep 2020 - present). Currently I am a visiting Ph.D. at The Hong Kong University of Science and Technology under the supervision of Prof. Long Chen. I visited Nanyang Technological University and Singapore Management University (as visiting Ph.D.), under the supervision of Prof. Hanwang Zhang and Prof. Qianru Sun (Sep 2022 - Sep 2023). I got my B.E. degree in Ocean engineering at Zhejiang University (Sep 2016 - Jun 2020).

Recent co-author: Dr. Jiaxin Shi

My research interests mainly include Computer Vision, Multimodal Analysis, and Video Generation and Editing.
