Research Interests
I am interested in the theoretical study of partial differential
equations arising from Mathematical Physics and Biology such as fluid dynamics,
kinetic theory and chemotaxis. Research topics include the Boltzmann equation,
Navier-Stokes equations and mixed-type equations with relaxation. By using
tools from PDE and Functional Analysis, I try to understand well-posedness and
large-time behavior for the Cauchy problem or initial boundary value problem.
