Biography
I am currently working as a research fellow at MMLab@NTU, Nanyang Technological University, under the supervision of Prof. Ziwei Liu. Prior to this, I served as a senior research scientist (2021-2023) at Tencent AI Lab.
I completed my Ph.D. degree (2017-2021) at the VILab of Harbin Institute of Technology, under the guidance of Prof. Hongxun Yao. During my Ph.D. study, I interned at SenseTime Research.
My research interests include computer vision and deep learning with a focus on 3D generation and reconstruction.
