Welcome to my professional home at the Max-Planck-Institut für Physik (MPP) in Munich. Details related to my present and past activities can be found following the menue given at the top of this page. Be aware that some of the information provided is in German. Finally, some links external to my web pages are also given.
I am a research physicist working within the international ATLAS collaboration performing high energy particle physics research at the Large Hadron Collider (LHC) at CERN in Geneva, Switzerland. At MPP I am leading our ATLAS group dealing with the Inner Detector. We have contributed to the design, construction, commissioning and operation of the SemiConductor Tracker (SCT). In 2009 we have changed focus and joined the Pixel Detector group. In the first long shutdown of the LHC we contributed to the refurbishment of the Pixel Detector and to the construction and commissioning of the new Insertable B-Layer (IBL) and its CO2 cooling system. Presently, our hardware focus is on the operation of the Pixel Detector and the develoment of novel thin planar pixel sensors for the planned upgrade of the ATLAS Inner Tracker (ITk) to be operated at the high luminosity phase of the LHC, the HL-LHC. We also perform physics analyses of ATLAS proton-proton collision data in the area of top quark physics, mainly concentrating on precision measurements of the top quark mass, and the related improvements in detector calibration and the reconstruction of physics objects. More details on past and present activities can be found at the Research Group web page.
Another area of research is the combination of measurements of physics observables, like the top quark mass, obtained from different experiments. In this context I have developed a software package named BLUE.
