Assistant Professor, Hong Kong University of Science and Technology (Guangzhou)

My research aims to build embodied spatial intelligence systems that enable robots to perceive their surroundings, maintain persistent spatial memory, predict the consequences of actions, and acquire robust skills for long-horizon interaction. This research integrates spatial perception, embodied foundation models, robot policy learning, and the co-design of robot bodies and sensing systems.

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.

I am actively recruiting motivated students and researchers to join the Embodied Spatial AI Lab at HKUST(GZ). Openings are available for MPhil students, research assistants, and interns starting in Fall 2026, and for PhD students starting in Spring/Fall 2027.

About Me

Assistant Professor @HKUST(GZ). Before joining HKUST(GZ), I was a Research Fellow at NUS in Singapore.

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

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.

Featured Projects

Research & Engineering Projects

We are actively recruiting motivated interns and research assistants to work on robotics, embodied AI, and intelligent systems.

Embodied Robot Platform Design and Development

We are developing next-generation embodied robotic platforms, including robotic arms, quadruped robots, dexterous hands, and tactile sensing systems.

The project focuses on the design and integration of robotic arms, quadruped robots, and customized robotic platforms for real-world applications.

We Are Looking For

We welcome motivated students, interns and research assistants with interests in:

Robot mechanical design Industrial design CAD / SolidWorks Robotics hardware development Robot control Sensor integration

Opportunities

Outstanding students may participate in the development of our in-house robotic platforms and contribute to future research projects in embodied AI.

Multi-Sensor Localization, Mapping and Navigation

We are building a next-generation multi-sensor localization and mapping system for autonomous inspection robots. The system integrates GNSS/RTK, LiDAR, RGB cameras, IMU, wheel odometry, and Gaussian Splatting-based mapping.

The goal is robust localization and high-fidelity 3D reconstruction in large-scale outdoor environments.

We Are Looking For

Students interested in robotics, SLAM, computer vision, and autonomous systems.

ROS2 FAST-LIO LIO-SAM RTK/GNSS VINS-Fusion Factor Graph 3D Reconstruction

Opportunities

Outstanding students may be recommended for HKUST(GZ) PhD admission.
