Current Position

Since December 2012, I am a doctoral student at the IGPM under the supervision of Prof. Dr. Wolfgang Dahmen.

The topic of my thesis is the design of a stable formulation for radiative transfer problems. It is based on a Discontinuous Petrov–Galerkin formulation for the spatial discretization and a wavelet-based discretization in the transport direction.

Research Interests

  • Stability in finite element methods (specifically, Discontinuous Petrov–Galerkin)
  • Reduced basis methods
  • Sparse grids

Current Research Work

  • Development of a Discontinuous Petrov–Galerkin method for the radiative transfer equation (with Wolfgang Dahmen and Olga Mula)
