About Me

My research is mostly concerned with stochastic differential equations (SDE) and distributional dependent SDE (DDSDE), and in particular the regularization by noise with singular and distribution drifts. My research includs the second-order kinetic systems, non-linear Fokker-Planck equations, propagation of chaos of N-particle systems and averaging principle for DDSDE.

I completed my PhD (Dr. Math.) in July 2023 at Bielefeld University , under the supervision of Prof. Dr. Michael Röckner and in June 2023 at Wuhan University, under the supervision of Prof. Dr. Xicheng Zhang. Before starting PhD, I finished my Bachelor at Wuhan University.
