I focus on 3D Vision and 3D Point Cloud technologies. My work primarily involves advancing the state-of-the-art in 3D data processing, computer vision, and machine learning.

• 3D Point Cloud learning semantic segmentation， especially applying sequence models (e.g., Attention, SSMs) to serialized point clouds.
• Other interests: Spatial Intelligence，3D reconstruction (e.g., MVSs, 3DGS, VGGT)、Self Supervised Learning (e.g., Superpoint, Sonata)
