Research interest

My research interest includes the numerical analysis of partial differential equations and applied dynamical systems. In particular, I am interested in:

Numerical methods for partial differential equations

  • (multiscale) finite element methods
  • structure-preserving time integration
  • nonlinear minimization problems
  • convergence analysis and a-priori error estimates
  • nonlinear Schrödinger equations, Gross-Pitaevskii equations, Ginzburg-Landau-equations
  • application to quantum physics: Bose-Einstein condensates and superconductivity

Analysis of nonlinear waves in evolution equations

  • dynamics of patterns
  • stability, existence and numerical computation of nonlinear waves
