Research informations

Research interests
  • PDEs of fluid dynamics: inviscid fluids, variable density, incompressible and compressible fluids, capillarity effects, geophysical fluids, MHD system.

  • Singular perturbation problems, asymptotic behaviour: fast rotation limit, incompressible limit, long-time dynamics, multi-scale limits.

  • Hyperbolic operators with low regularity coefficients (second-order equations, first-order systems): well-posedness, control and optimal control.
