After studying physics at Technical University of Munich, I did my PhD at Max-Planck-Institut for physics (Werner Heisenberg Institute) in Munich under the supervision of Uli Nierste and Andrzej Buras. I was working at that time on higher order QCD corrections to B meson decays. In 1999 I switched to the chair of Vladimir Braun at Regensburg and I started to work also on sum rules as well as different new physics models (in particular SUSY and 4th generation) - 6 years later I did my habilitation in Regensburg. In 2005 I received the Prize for excellent Teaching from the Bavarian government. From 2010 on I had temporary professorships in Regensburg (W2), Dortmund (W2) and TU Munich (W3). End of 2011 I started a Heisenberg-fellowship at CERN, which I quit after only one year to start as a lecturer at Durham University. Currently I am professor and deputy director of the IPPP.

Research Interests

I am basically interested in finding the correct extension of the standard model that will also allow to explain the existence of matter in the universe as well as the nature of dark matter. To come closer to the solution of this ambitious goal numerous small steps have to be undertaken. First real deviations of experiment and standard model have to be identified. Therefore we need control over the hadronic uncertainties of the theory predictions. Then the theoretical structure of possible deviations has to be investigated - this can be done in a model-dependent and a model-independent way. Finally cosmological consequences of modification of the standard model have to be studied.

What does a physics professor do in his spare time?

I spend a lot of time in supporting my family and my friends.

Besides my professional interest in theoretical particle physics I am also keen on applied research, in particular on subtle effects of the General Theory of Relativity on different test particles in the gravity field of the Earth. In that respect I regularly participate in expert meetings on applied gravity.

In contrast to most of my physics colleagues, I highly respect other sciences like chemistry - I regularly travel with like-minded people far in order to be able to study and appreciate the outcome of chemical investigations at remote research laboratories.
