I am a Research Assistant Professor (in job market now) at the Department of Mathematics of The Chinese University of Hong Kong. Previously, I was a post-doctoral researcher at Laboratoire de Mathématiques AGM, Cergy Paris Université, worked with Prof. Christophe Prange and Prof. Charles Collot. I completed my PhD in Mathematics under the supervision of Prof. Raphaël Danchin and Prof. François Vigneron at Laboratoire d’analyse et de mathématiques appliquées, Université Paris-est Créteil.

I am interested in Partial Differential Equations. Specifically, the regularity theory and the time-relaxation limit of fluid equations.
