Research Interests
My research interests fall into the areas of geometric modeling, computer graphics, 3D vision, 3D deep learning, and digital twins. In particular, I am interested in:- Foundational point-cloud processing, including denoising, normal estimation, sampling, registration, completion, and feature detection.
- Implicit field learning for point clouds and subsequent surface meshing.
- Scene understanding and instance-level reconstruction.
