Research Fellow, National University of Singapore · Incoming Assistant Professor, Hong Kong University of Science and Technology (Guangzhou)

My research focuses on robotics, spatial AI, SLAM, 3D/4D scene representation, and Gaussian Splatting. I am interested in how robots can perceive the physical world, build persistent internal models, understand geometry and dynamics, and act intelligently over long horizons. I completed my master's and PhD at Peking University and the Technical University of Munich, where I worked on nonlinear least-squares optimization and Geometric Computer Vision.

My long-term goal is to build next-generation intelligent robots from body to mind, combining robot hardware, spatial understanding, persistent world modeling, and robot action policy learning.

I am actively recruiting motivated PhD and MPhil students, research assistants, and interns to join Embodied Spatial AI Lab at HKUST(GZ), starting from Fall 2026 and Spring 2027.

About Me

I am currently a Research Fellow at the National University of Singapore and will join HKUST(GZ) as an Assistant Professor in August 2026.

I serve as an Associate Editor for IEEE RA-L, an Area Chair for IROS 2026, and a Lead Organizer of the IROS 2025 Workshop AIR4D.

Research Program

My research focuses on building embodied spatial intelligence systems that enable robots to perceive, model, reason about, and interact with complex real-world environments.

Embodied Perception

Geometry-aware perception systems that enable robots to localize, map, and understand complex real-world environments through spatially consistent representations.

Spatial World Modeling

Persistent 3D and 4D world models that support long-horizon robot autonomy through geometry-centric tracking, reconstruction, and structured scene representations.

Robot Learning and Action

Learning-based robot systems that connect perception, representation, and reasoning with decision-making and interaction in dynamic environments.
