I am an experimental physicist in high energy particle physics. My current research projects are in association with the ATLAS experiment at the Large Hadron Collider at CERN near Geneva, Switzerland. Prior to coming to Oxford I was a researcher with the University of Pittsburgh doing research at the Collider Detector Facility (CDF) at the Fermi National Accelerator Laboratory, where my research was searching for, and then finding and studying, the B_c meson (a particle consisting of the bound pairing of a bottom quark and a charm quark).

Research interests

Searching for two and three Higgs boson production at the Large Hadron Collider at CERN. In the standard model of particle physics these are cases where the Higgs boson spawns additional copies of itself. This is interesting because the Standard Model predicts the rates of multi-Higgs production but it critically depends on the exact shape of the Higgs potential. So measuring these states help us uncover what that potential actually is.


Within Oxford I currently Lecture and tutor in circuit Theory for the first and second year courses. I also tutor quantum physics, 3rd year Special relativity and covariant electromagnetism, 3rd year sub-atomic physics, and first and second year calculus and linear algebra.

I also supervise Project students every year and usually have at least one graduate student working in my research areas.
