Jiahe Li

李嘉禾

I am a fourth-year PhD student at Beihang University, advised by Prof. Xiao Bai, and currently a visiting PhD student at NUS, advised by Prof. Gim Hee Lee. I received my Bachelor's degree from BUPT in 2022. My research focuses on 3D computer vision, especially 3D reconstruction and cross-modal generation.
