Forschung - Research

I am working as a theoretical physicist. My interest lies in elementary particle physics and statistical physics, in particular Lattice Field Theory. During recent years I have been publishing papers on

  • Gauge theories
  • Real space renormalization group
  • Phi4-theories
  • Lattice QCD
  • Gauge-Higgs systems
  • Scattering in lattice systems
  • Statistical physics problems
  • Fancy actions and lattices (e.g. spherical)
  • 2D models (e.g. Schwinger model)
  • Random matrix theory
  • Chirally improved Dirac operators

Before doing lattice field theory I had been working in S-matrix theory and in particular meson-meson scattering phenomenology.

Research Projects

I have been leading the following funded research projects

I was one of the directors of the Doktoratskolleg "Hadrons in Vacuum, Nuclei and Stars", FWF Doktoratskolleg W1203-N08 (2006-2018)
