Biography

My current research interests are partial differential equations, nonlinear analysis, kinetic theory, and fluid dynamics, especially the Boltzmann equation and the relativistic Boltzmann equation in general relativity. The research topics include boundary theory, wave patterns, spectral analysis, existence and regularity, fluid dynamic limit, pseudo-differential calculus, semigroup theory, rate of convergence, etc.
