Research Interests: 

My research centers on the search for new physics at high energies, using data from the ATLAS experiment at the Large Hadron Collider (LHC).   My work has included searches  for a new class of particles called "vector-like quarks" whose existence could explain some of the odd features of our current theories of fundamental particle physics, and my present focus is on searching for new scalar bosons that are more massive than the Higgs boson.  I am also involved in the development of a track-based trigger system that will help to cope with the data rates when the LHC is upgraded to run at much higher intensity in the coming years, and in the design of a detector for the next-generation particle accelerator, the Future Circular Collider.
