Particle Theory Group

Research Interests

Our research addresses questions about fundamental building blocks of the subatomic world and of our Universe:

  • Particle phenomenology and physics beyond the Standard Model: Flavor, LHC, electroweak precision
  • Particle astrophysics& cosmology: Dark matter theory and phenomenology
  • Topics in quantum field theory: Unification, asymptotic safety
