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
