Christian does research in Elementary Particle Physics, Computational Physics and Theoretical Physics. His interest lies in elementary particle physics and statistical physics, in particular Lattice Field Theory. He has been publishing papers on Real space renormalization group, Phi4-theories, Lattice QCD, Gauge-Higgs systems, Statistical physics, 2D models (e.g. Schwinger model), Chirally improved Dirac operators, Resonances and scattering in lattice QCD. Before doing lattice field theory he had been working in S-matrix theory and in particular meson-meson scattering phenomenology.
