About Me
I obtained my Ph.D. degree in Computer Science at City University of Hong Kong, supervised by Prof. Junhui Hou. I was also fortunate to work closely with Prof. Ying He from NTU and Prof. Wenping Wang from TAMU. Previously, I worked as a research intern guided by Prof. Runmin Cong. I received my B.Sc. degree in Electronic Information Science and Technology at Beijing Normal University.

Research
The latest trend in the artificial intelligence era continues to blur the boundaries of different research domains and data modalities. In general, I have broad interests in developing deep learning models to solve various geometry, vision, and graphics problems.
My research during Ph.D. mainly includes the following tasks and topics:
- Geometric (Mesh, Point Cloud, Implicit Field) Computing and Modeling;
- Neural 3D Representation, Rendering, Reconstruction, and Generation;
- Multi-Modal (2D-3D, Visual-Geometric) Learning: Pre-training, Alignment, Fusion, Distillation.
I am particularly interested in Neuralized Geometry Processing, i.e., (1) (at the data level) exploring neural representations for geometric data; (2) (at the model level) replacing conventional geometric computation/optimization algorithms with more powerful neural architectures.
My current research concentrates on 3D Generative Models and AI for Games.
