Prof. Dr. Cigdem Issever

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 and leader of the particle physics group at DESY Zeuthen.

My Research

My research focuses on understanding the underlying mechanism of how mass is generated in nature and what Dark Matter could be. 

My current research interests are:

  • Higgs Self-Coupling measurement with di-Higgs final states at the Humboldt University of Berlin
  • Development of advanced algorithms for particle identification for the LHC
  • Forward cross-section measurements with ATLAS and LHCf experiments
  • Digital Calorimeter R&D
  • Searches for Dark Matter signatures with quantum sensors;

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. My research group is also contributing strongly into the development and operation of the ATLAS Trigger.

Besides 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.
