Scientific interests

numerical analysis and simulation of turbulent flows, large eddy simulation (LES), variational multiscale methods (VMS)
efficient and robust multigrid based solvers for the numerical solution of the incompressible Navier-Stokes equations
finite element discretizations for problems arising in CFD, e.g. higher order finite element discretizations for the incompressible Navier-Stokes equations
adaptive methods and a posteriori error estimators for partial differential equations coming from fluid dynamics
stabilized methods for convection-dominated problems
numerical simulation of population balance systems
