Research Interests

My research focuses on experimental particle physics with the CMS Collaboration at the Large Hadron Collider (LHC) at CERN in Switzerland. I am particularly interested in rare decays and CP violation, dark matter and Higgs physics.

  • 2023-2025: Convener, B Physics and Quarkonia
  • 2020-2022: Coordinator, Exotic and Rare Decay subgroup of the B Physics group
  • 2017-2019: Convener, Muon Physics Group
  • 2014-2015: Coordinator, Multiboson subgroup of the Standard Model group
  • 2012-2013: Coordinator, WW subgroup of the Higgs group
