Research Interests and Contributions


In my research, I study the properties of elementary particles in order to understand the nature of the fundamental building blocks of our universe. I analyze data taken with the ATLAS detector in proton-proton collisions at CERN’s Large Hadron Collider and I am especially interested in studying the properties of the Higgs boson and the top quark and in searching for still unknown heavy particles. I work on new methodology and algorithms for data analysis at collider experiments and in particular on the development of machine-learning applications for the Large Hadron Collider.

Contributions:

  • Searches for new particles (heavy quarks, dark matter, heavy W and Higgs bosons)
  • Higgs physics, especially measurements of the Higgs-boson’s coupling to the top quark
  • Top-quark physics (searches for rare processes)
  • Development of methodology for data analysis at the Large Hadron Collider
  • Development of machine learning applications at the Large Hadron Collider
