About Me
I’m now a first-year PhD student in computer science at the University of Maryland (College Park), working with Prof. Matthias Zwicker. Before that, I got my master’s degree in Data Science and Information Technology at TBSI, Tsinghua University(THU), supervised by Prof. Lu Fang and Prof. Qionghai Dai. Prior to that, I spent wonderful 4 years at Sun Yat-Sen University(SYSU), and obtained my bachelor’s degree in 2021.
My research interests mainly lie in 3D computer vision, especially in:
- 3D Representation: Geometric Primitive based 3D Modeling (such as Quadrics and CAD)
- 3D Reconstruction: Semantic-aware Reconstruction and Rendering from images and video
- 3D Understanding: Hierarchical 3D Scene Parsing and Navigation
My goal is to model, reconstruct, and manipuate the 3D world in a more efficient and interpretable manner.
