Biography

I am a PostDoc at The University of Hong Kong (HKU). Before that, I received my Ph.D. degree at the Interdisciplinary Research Center (IRC), Shandong University (SDU) in 2024, under the supervision of Prof. Shiqing Xin. I got the Joint-M.Eng. degree from the Fujian Institute of Research on the Structure of Matter, Chinese Academy of Sciences (FJIRSM)-North University of China in 2020, advised by Prof. Shengzong Zhou. I am fortunate to work closely with Prof. Wenping Wang and Prof. Changhe Tu.

My research interests include Mesh Feature Extraction, Surface Reconstruction from Point Cloud, and Quad Mesh Generation.
