About Me

I am currently serving as the Algorithm Team Lead at TopXGun (Nanjing) Robotics Co., Ltd. in China, where I lead a small team focusing on SLAM, Perception, 3D Reconstruction, and Coverage Path Planning for UAV autopilot systems. Previously, I received an M.Sc. in Multimedia Information Technology from the City University of Hong Kong, supervised by Prof. Ho Man Chan.
My research interests lie in SLAM, Spatial AI, and Robotics, particularly in the following areas:

Multi-sensor fusion SLAM and Structure-from-Motion (SfM).
Feed-forward 3D reconstruction, such as 3D Gaussian Splatting and VGGT.
Cross-view and cross-domain place recognition.
