Ulrich Husemann

Prof. Dr. Ulrich Husemann is a Professor of Experimental Particle Physics at the Institute of Experimental Particle Physics (ETP) of the Karlsruhe Institute of Technology (KIT). He leads research in CERN's CMS experiment, focusing on top quark physics, Higgs boson coupling measurements, and dark matter detection using machine learning techniques. His work also explores medical applications of semiconductor detectors for radiotherapy.

• 2024: Co-convener of the Physics Preparatory Group for the European Strategy for Particle Physics
• 2024: Organizer of the German Physical Society Spring Meeting on Particle Physics
• 2023: KIT Senate member
• 2021–2023: Vice Dean at KIT Department of Physics

His research spans detector system development and data analysis for hadron colliders, including contributions to the CMS Phase-1 Pixel Detector Upgrade (2017) and Phase-2 Silicon Strip Tracker for the High-Luminosity LHC. Medical applications include evaluating HV-CMOS technology for beam monitoring in ion therapy with Heidelberg Ion Beam Therapy Center.

Recent publications focus on ttH/tH production rates (2025), ttbb cross-section measurements (2024), and machine learning integration in particle physics (2024). Earlier works (2005–2018) address rare top quark decays, silicon detector radiation effects, and LHC/HL-LHC sensitivity projections.

He teaches courses on Computer-Guided Data Analysis, Accelerators and Detectors, and Modern Experimental Physics. As of spring 2025, he has supervised 20 doctoral theses, 50 Master's theses, and over 90 Bachelor's theses.
