😀️ Biography

I am currently a graduate student at Sun Yat-sen University, advised by Prof. Mengyuan Liu (Assistant Professor in PeKing Uiniversity).

I received a B.S. degree from Jinan University.

My research focuses on 3D Point Cloud Analysis and In-Context Learning. I am also highly interested in Large Language and Multimodal Models.

I am fortunate to have the opportunity to collaborate with Dr. Xia Li (ETH Zurich) and Dr. Xiangtai Li (MMLab@NTU).
