Dr. Jingrui Sun is an Associate Professor at the Southern University of Science and Technology. He earned his Ph.D. degree from the University of Science and Technology of China in 2015. From April 2015 to February 2019, he held research and teaching positions successively at The Hong Kong Polytechnic University, the National University of Singapore, and the University of Central Florida before joining the Department of Mathematics at the Southern University of Science and Technology in February 2019.

In 2019, he was honored with the "Peacock Program" Class C title for high-level overseas talents in Shenzhen. In 2023, he independently received the "SIAG/CST Best SICON Paper Prize" awarded by the Society for Industrial and Applied Mathematics (SIAM). Dr. Sun has led various projects, including one National Natural Science Foundation of China Excellent Young Scientist Fund project, one National Natural Science Foundation of China General Program, one National Natural Science Foundation of China Youth Science Fund project, one Guangdong Basic and Applied Basic Research Foundation project, and one Shenzhen Fundamental Research General Program. He has also participated in a National Key R&D Program of China and is a core member of the Shenzhen Key Laboratory of Safety and Security for Next Generation of Industrial Internet.

His research primarily focuses on stochastic control and its applications. Dr. Sun has authored two specialized books published by Springer and has contributed over 20 academic papers to renowned journals such as the SIAM Journal on Control and Optimization, Annals of Applied Probability, ESAIM: Control, Optimisation and Calculus of Variations, Stochastic Processes and their Applications, Journal of Differential Equations, Applied Mathematics and Optimization, and Discrete and Continuous Dynamical Systems-A.
