### My research interests

I am interested in the origins of the masses of the fundamental particles. I have been involved in the search for the Higgs boson in its incarnation within the Standard Model and in a number of supersymmetric models. I was one the two official representatives of the D0 experiment on the Tevatron New Physics and Higgs Working group. This group performs the statistical combination of the results of Higgs searches at the two experiments that ran at the Tevatron proton-anti-proton collider at Fermilab near Chicago, IL. I was also an important contributor the continuing search for the standard model Higgs boson for the CMS experiment at the LHC at CERN, working on the key channel where the Higgs boson decays to two photons. This culminated in the discovery of a Higgs-like boson in July 2012. My work in Higgs physics now continues on the ATLAS experiment where I am interested in measuring the physical properties of the new boson and how it interacts with the other fundamental particles. These measurements will reveal the nature of the new particle and tell us whether we have indeed found the boson predicted by the standard model, or perhaps something new that we cannot yet explain.

### My teaching

Currently, I tutor for the Synoptic Physics module(PHY300) that runs in Semester A and am module organiser for the module on Introduction to C++ Programming (PHY4321) that runs in Semester B.
