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 lies at the intersection of Computer Graphics and Deep Learning. More specifically, I focus on geometric deep learning, including quadrilateral mesh generation, point cloud–based surface reconstruction, and mesh feature extraction, among others.

董秋杰，2024年博士毕业于山东大学计算机科学与技术学院交叉研究中心，导师为辛士庆教授；2024—2025年在香港大学从事博士后研究。长期面向智能制造与CAD/CAE等应用需求，围绕“几何深度学习驱动的网格生成与处理”开展系统研究，重点突破四边形网格生成、点云曲面高保真重建与网格特征提取等关键问题。已在 ACM Transactions on Graphics、SIGGRAPH (Asia)、IEEE TVCG 等国际高水平期刊与会议发表论文十余篇，并受邀在 GAMES 等学术平台作七场学术报告。代表作 Laplacian2Mesh 入选 ESI 高被引论文，曾获2025年度“CSIAM GDC优秀博士论文激励计划”、山东省优秀毕业生等荣誉。现任中国工业与应用数学学会几何设计与计算专委会委员及秘书处干事。

I am currently seeking job opportunities. Please feel free to reach out if you have a suitable position available.
