About Me

I am a forth-year PhD student in the School of Computer Science and Engineering at Beihang University, advised by Prof. Xiao Bai. Before that, I got my Bachelor's degree at BUPT in 2022. Currently, I'm a visiting PhD student at Computer Vision and Robotic Perception Laboratory, NUS, advised by Prof. Gim Hee Lee. My research interest lies in the field of 3D Computer Vision, particularly including 3D reconstruction and its applications in cross-modal generation.
