I'm a registered UK STEM Ambassador, and am DBS/CRB/Disclosure Scotland certified. I'm very happy to talk about my work or any aspect of particle physics, at outreach events or to the media (maybe). In recent years I have been increasingly involved in direct tests of new physics compatibility with data, via a mix of modelling and machine learning techniques, in the GAMBIT, TopFitter, and Contur experiment/theory collaborations. I also have one foot in the parton density fitting community through my work on the LHAPDF library. In previous roles I was convener of ATLAS' MC generator working group, overseeing the simulation used in the 2012 Higgs boson discovery, and spent several years in charge of the ATLAS simulation via the Geant4 toolkit. I am the lead author of the Rivet analysis framework, the Professor parametrisation tool, and created many of the LHC's most heavily used MC generator "tunes". ![]() My engagements with particle theory range from optimising simulations of particle interactions. Better understanding of this corner of the Standard Model will enable us to do more detailed searches and studies of Higgs boson and beyond-Standard-Model physics. On the experimental side, I'm principally interested in measuring QCD (the nuclear strong force) in both its perturbative and non-perturbative regimes: in particular I have been involved in several measurements of the "underlying event" at LHC, and am interested in how heavy flavour (charm and bottom quarks) behaves at hadron colliders. I'm a particle physicist, working on the boundaries between experimental studies with the ATLAS experiment (part of the Large Hadron Collider at the CERN lab in Geneva) and theoretical work on modelling of hadron collisions, and on constraining prospective models of new physics. ![]() Principle investigator of Glasgow ScotDIST centre for doctoral training.
