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
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
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]
