Research
Research Interest:
My main research areas are in mathematical physics and partial differential equations, studied from both pure and applied points of view.
Pure Math: analysis of deterministic and stochastic partial differential equations including well-posedness, global existence, blow-up, scattering, solitary wave, asymptotic behavior and classification of solution.
Applied Math: Numerical simulation for nonlinear PDEs in various domains.
