Haoang Li

Welcome to my homepage! I am Haoang Li (pronounced as "Horn Lee"). I am currently an Assistant Professor at The Hong Kong University of Science and Technology (Guangzhou).

My research interest lies in 3D computer vision and robotics. Previously, I mainly focused on geometric SLAM and 3D reconstruction. Currently, along with my students, we are working on the following directions:

Embodied AI: 1) Vision-language action/manipulation; 2) Vision-language navigation; 3) Humanoid perception and control
AI-generated content: 3D/4D scene synthesis
3D/4D reconstruction and rendering: 1) Gaussian splatting/NeRF; 2) Dynamic SLAM; 3) Human avatar

We are working closely with Prof. Hesheng Wang from Shanghai Jiao Tong University.

I serve as an Associate Editor of ICRA, a Registration Chair of IROS 2025, and reviewers of top-tier journals and conferences.

Our work was selected as CVPR 2025 Best Paper Candidate. We also won ICCV 2021 Doctoral Consortium Award, third place in ICRA 2025 RoboDrive Challenge, CVPR 2021 Outstanding Reviewer Award, etc.

We are continuously looking for Ph.D. students, Research Assistants, and Interns/Visiting Students working on the above directions. For details, please refer to 小红书.
