About me

I am currently a fourth-year Ph.D. student in the Department of Computer Science, National University of Singapore (NUS), supervised by Prof. Tat-seng Chua and Prof. Gim Hee Lee.

My research interests include: (1) Computer Vision: 3D computer vision, 3D scene understanding, 3D object detection, 3D semantic segmentation. (2) Machine Learning: semi-supervised learning, few-shot learning, incremental learning, unsupervised/self supervised learning.
