I am an experimental particle physicist and member of the ATLAS collaboration at CERN. I am head of the Experimental High Energy Group at the Humboldt University of Berlin and a leading scientist at DESY.

My Research

My research focusses on the understanding of the Dark Matter content of the universe and the underlying mechanism of how mass is generated in nature.

My current research interests are

  • the search for Dark Matter signatures in di-jet, jet + Higgs final states at DESY;
  • and Higgs Self-Coupling measurement with di-Higgs final states at the Humboldt University of Berlin.

I actively work on the calibration and performance studies of jets in the ATLAS detector. I am also using my expertise in jet reconstruction to improve the b-jet identification in ATLAS which is important for my research in jet+Higgs and di-Higgs final state where the Higgs bosons decay into a pair of b-quarks.

Beside my ATLAS research I am also interested in generic detector R&D, in particular the development of high spatial and time resolution calorimeters with potential medical applications.
