Theoretical Particle Physics

Research Interests

My dominant research interests lie in the field of theoretical elementary particle physics.

I am largely interested in the interplay of models of physics beyond the standard model an their experimental manifestations. Most of my work concerns issues in flavour physics such as rare decays, CP-violation or various effects of supersymmetry.

My recent work has dealt with precision calculations in rare B-meson decays, with the physics of neutrinos and with QCD-issues in B-meson decays. Current interests include supersymmetry and rare decays, investigations of the supersymmetric phenomenology in models with hierarchical masses (an example is split supersymmetry), axion and axino physics, fundamental issues in the calculation of radiative corrections and effective QCD analyes in the decays of heavy quarks.
