Biography

I am currently working as a research fellow at MMLab@NTU, Nanyang Technological University, working with Prof. Ziwei Liu. Previously, I was a Senior Research Scientist at Tencent AI Lab from 2021 to 2023.

I received my Ph.D. from the VILab at Harbin Institute of Technology in 2021, supervised by Prof. Hongxun Yao. During my Ph.D., I also interned at SenseTime Research, mentored by Dr. Wenxiu Sun.
