I mainly work on analysis/computations for PDEs from materials sciences, biology, and microfluids. I recently focus on optimal control and Hamilton-Jacobi equations with applications in transition path theory, mean-field limit, large deviation principle and non-equilibrium chemical reactions.
My research is supported by NSF Award DMS-2204288.
