Research interests
My research interests fall into main four categories: In the area of dynamical systems, my research focuses on infinite dimensional dynamical systems, random dynamical systems, biological systems, set-valued dynamical systems and lattice systems. In the field of partial differential equations, my research focuses on nonlinear parabolic PDEs, wave equations, Navier-Stokes equations, quasi-geostrophic equations, reaction diffusion equations, functional differential equations, fractional PDEs. In the field of probability, I am interested in the probabilistic approach of PDEs, stochastic differential equations, stochastic processes, finance, atmospheric science and stochastic control theory. Fourthly, I am interested in numerical analysis, especially the rates of convergence of finite difference approximations, Galerkin finite element approximations and spectral method.
