Current Position

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

Research Interests

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

Current Research Work

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


Most webpages of older courses have unfortunately been lost in a CMS migration.

Master's Thesis

I did my master's thesis in 2012 at the IGPM under the supervison of Prof. Dr. Wolfgang Dahmen.
