WANG, Xuefeng


Education Background

Ph.D degree (University of Minnesota)

Bachelor's degree (Peking University)


Research Field
Partial Differential Equations and Applications

Prior to joining CUHKSZ in August, 2019, Prof. Wang worked at Tulane University for 26 years; and at Southern University of Science and Technology during 2016-2019. He has  been teaching, non-stop except when he was on sabbatical leaves. He has taught many courses ranging from freshmen Calculus, to topics courses for Ph.D students. Professor Wang's research field is partial differential equations (PDE). Some of his research topics are meant to discover new mathematical phenomena and provide new insights, or demonstrate new methods/ideas via specific, prototype PDEs in a simple and crystal-clear framework; the other topics (e.g. global bifurcation theory, and Krein-Rutman theory) are meant to provide general, yet user-friendly tools for workers to use when attacking sophisticated PDE models arising in applications.
