Biography
Currently, he is a research fellow at Nanyang Technological University (NTU) Singapore, working with Prof. Ziwei Liu.
Prior to this, he worked as a Research Scientist at the Sea AI Lab of Sea Group.
He completed Ph.D. degree in 2021 at CASIA, supervised by Prof. Tieniu Tan, co-supervised by Prof. Liang Wang and Prof. Wei Wang.
His research lies at the intersection of deep learning and computer vision, including vision-based human perception (pose and action), few-shot learning, self-supervised learning, semi-supervised learning, in-context learning and video generation.
