About
I am an Associate Professor in the School of Mathematics and Statistics at Nanjing University of Science and Technology. I received my Ph.D. from Fudan University in 2018.
My research focuses on approximation theory and numerical methods for partial differential equations, especially kernel-based and meshless methods.
Research interests
- Scattered data approximation
- Radial basis functions
- Meshless methods for PDEs
- Structure-preserving numerical schemes
