I am on sabbatical in Austin for Fall 2024 - Spring 2025.

Curriculum Vitae

Research Interests

I am interested in nonlinear PDEs arising in physics (Fluid dynamics; Kinetic theory; Hyperbolic conservation laws, especially shock waves, Euler equations, Navier-Stokes equations), more precisely in well-posed/ill-posed problems; asymptotic analysis (hydrodynamic limit; inviscid limit)
