| Submission declined on 9 July 2024 by The Herald (talk). This submission's references do not show that the subject qualifies for a Wikipedia article—that is, they do not show significant coverage (not just passing mentions) about the subject in published, reliable, secondary sources that are independent of the subject (see the guidelines on the notability of people). Before any resubmission, additional references meeting these criteria should be added (see technical help and learn about mistakes to avoid when addressing this issue). If no additional references exist, the subject is not suitable for Wikipedia. This submission reads more like an essay than an encyclopedia article. Submissions should summarise information in secondary, reliable sources and not contain opinions or original research. Please write about the topic from a neutral point of view in an encyclopedic manner. Declined by The Herald 48 days ago. | |

Defeng Sun (Chinese name: 孙德锋) is a Chinese applied mathematician and operations researcher. He holds the position of Chair Professor of Applied Optimization and Operations Research, and has been serving as the Head of Department of Applied Mathematics since 2019, and the Director of the Research Centre for Intelligent Operations Research (2024 - present) at The Hong Kong Polytechnic University (PolyU). Sun had also served as the President of The Hong Kong Mathematical Society in 2020-2024.
Education
[edit]Sun received his Ph.D. degree in 1995 from Chinese Academy of Sciences in Beijing under the supervision of Professor Jiye Han (Chinese name: 韩继业), after obtaining his bachelor’s and Master’s degree from Nanjing University in 1989 and 1992, respectively.
Research
[edit]Sun’s research interests lie in the areas of non-convex continuous optimization and machine learning including mathematical theory, algorithmic developments and real-world applications.
Sun is recognized for his 2006 work characterizing the strong regularity of nonlinear semidefinite programming[1] and his software SDPNAL/SDPNAL+ for general purpose semidefinite programming[2]
