Biography

I am a professor in the Department of Physics and at the Institute for Particle Physics Phenomenology

My research concerns obtaining predictions for the outcome of high-energy collisions of particles at e.g. CERN's Large Hadron Collider. In particular, my work has focused on developing an efficient formalism for the study of the dominant perturbative corrections from QCD in the regions not just dominated by not just one hard scale, but two.

Precise predictions for such processes are both difficult and necessary to obtain, since they are systematically enhanced compared to the normal expectation of (small) perturbative corrections. This happens particularly in the regions of phase space that happen to be of special interest for other reasons: Such regions are of specific interest in connections with the study of the coupling between a Higgs boson and two bosons of the weak force (Higgs production through Vector Boson Fusion), and the coupling of three weak bosons (aka. Vector Boson Scattering). Such studies require a clean separation between the processes orginating from strong and from weak interactions - and although the initial and final state at the lowest perturbative order are the same (and one therefore might think the processes are indistinguishable), the quantum corrections are very different and allow for a distinction. If we can calculate them reliably.

Apart from the very practical question of relevance to the interpretation of experimental data, the study of the high-energy behaviour of scattering amplitudes is also interesting in its own right.
