I am a second-year Ph.D student in the Department of Computer Science, The University of Hong Kong (HKU), supervised by Dr. Hengshuang Zhao. Before that, I obtained a Bachelor of Science in Mathematics from Sun Yat-sen University, supervised by Dr. Guanbin Li.

My current research interests and focus: 1. 3D Representation and Perception; 2. Combination of 3D Perception and Robotic; 3. Combination of 3D Vision and LLM. More experiences about me please refer to my publications and my Google Scholar. Reach out to me over email for discussion or any opportunities.
