😀️ Biography
I am currently working in Tencent. Before that, I received my M.S. degree in Sun Yat-sen University, advised by Prof. Mengyuan Liu (Assistant Professor in PeKing Uiniversity).
My research focuses on 3D Point Cloud Analysis, In-Context Learning, and AIGC..
I am fortunate to have the opportunity to collaborate with Dr. Xia Li (ETH Zurich) and Dr. Xiangtai Li (MMLab@NTU).
