From February 2009 to February 2012, I was Fellow of the Helmholtz Alliance ''Physics at the Terascale'' working together with the AG van der Bij and the AG Dittmaier. As of March 2012, I switched to SAP

Teaching

In the winter semester 2007/2008, I took over a professor replacement position here in Freiburg doing a course on relativistic quantum field theory (see homepage of the course "Relativistische Quantenfeldtheorie" ).
In 2010, I gave a block course "Supersymmetry" at the 42. Herbstschule für Hochenergiephysik Maria Laach.
Have been asked to give the course again in 2011. This year "Maria Laach" is in Bautzen.

Programs

HiggsBounds : (new release since 19/10/2011: version 3.5.0beta) a code which can decide for models with arbitrary numbers of neutral and charged Higgs bosons, with given deviations from reference (usually Standard Model) Higgs production cross sections and decay branching ratios, whether it is excluded at the 95% C.L. or not.
If you are interested in the code, please have a look at our WWW interface and download section.
For more information, please have a look at the slides of the talk I gave 2010 in Uppsala.
This work is done in collaboration with Philip Bechtle, Sven Heinemeyer, Tim Stefaniak, Georg Weiglein and Karina Williams.
HJET : FORTRAN code which allows to calculate the cross section of Higgs + jet production at hadron colliders in the MSSM/SM which is mediated by the subprocesses: g g --> H g, q g --> H q, q q-bar --> H g. The code allows to calculate hadronic cross sections differential in jet transverse momentum, jet pseudorapidity, invariant mass of the final state particles, and two-fold differential in the jet's transverse momentum and pseudorapidity.
Important bugfix in new version 1.3 ! Please have a look at the program's README file For more information on the calculation, please consult the journal references:
Phys. Rev. D68 (2003) 095006 (hep-ph/0305321) and Phys. Rev. D76 (2007) 035002 (0705.2744 [hep-ph]).
eeWH : FORTRAN code which allows to calculate the cross section for e⁺ e^- --> W^+/- H^-/+ in the MSSM and the THDM.
See Eur. Phys. J. 52 (2007) 397. (hep-ph/0610079) for details.
FORTRAN programs for the calculation of other Higgs boson production cross sections, like
- p p --> H⁺ H^-,
- p p --> W^+/- H^-/+,
in the framework of the MSSM and THDM, are also available, but not yet prepared for public use.
adScan : FORTRAN code for a sample program demonstrating the ''adaptive scanning'' method described in Comput. Phys. Commun. 170 (2005) 42 (hep-ph/0407340).

Please contact me, if you are interested in one of the programs.

Before I came here, I worked at the Institute for Particle Physics Phenomenology (IPPP) in Durham, and the Institut für Theoretische Physik E in Aachen, and the Werner-Heisenberg-Institut in Munich, and before that I did my doctoral thesis and diploma thesis at the Institut für Theoretische Physik in Karlsruhe (homepage).
