Welcome to my academic webpage!

About me

I am a PhD student in numerical analysis under the direction of Alexandre Ern, Zhaonan Dong at CERMICS, Ecole Nationale des Ponts et Chaussées, Institut Polytechnique de Paris and SERENA team, Inria Centre de Paris. I am also co-supervised by Jean-Luc Guermond at Texas A&M University.

As an applied mathematician, I am mainly interested in design, test and analyze efficient numerical schemes for PDEs. My work mainly focus on structure-preserving schemes for nonlinear PDEs, including hyperbolic conservation laws, PDEs with stiff sourse, and nonlinear parabolic problems.

As a guy with diplôme d'ingénieur (engineer degree in French), I am also interested in 1) the implementation with C++, Python, Matlab and Julia(currently using). 2) Physics-related mathematical modeling.

I am currently speaking Chinese, English, French and studying Japanese.
