I am a PhD student on the ATLAS Experiment in the Oxford supersymmetry group. My research interests are designing discovery strategies for supersymmetry and dark matter at the energy frontier.

Phenomenology of supersymmetric dark matter
My theoretical analysis of early 13 TeV search techniques for new coloured particles identified the so-called 'Higgsino' as a promising candidate for dark matter in a 19-parameter 'pMSSM' supersymmetry framework.

New experimental search strategies
With international collaborators, I devised and led a dedicated experimental search opening sensitivity to Higgsino dark matter beyond LEP for the first time in nearly two decades by targeting very challenging 'compressed scenarios' of electroweak supersymmetry using low momentum leptons.

Technical detector responsibilities
Essential to these experimental results is my technical expertise in the operational performance of the ATLAS silicon tracker detector, trigger strategy design, and simulation software for new physics signatures.
