About Me

I am a first year Mphil student at the Deparment of Electronic Engineering, The Chinese University of Hong Kong. I received my B.E. degree at the College of Intelligence and Computing, Tianjin University, where I have grad honor to work closely with Prof. Changqing Zhang. I'm currently focusing on 3D Computer Vision, especially VLM for 3D and 3D Feed Forward Models.
