Research summary

I work on particle physics, in the gap between experiment and theory where the modelling of high-energy processes takes place. Around this core activity I measure properties of collision events at the Large Hadron Collider (LHC) at CERN in Geneva, where I am a member of the ATLAS collaboration, and use LHC data to place statistical limits on models of New Physics.

In the last year I completed work on using early 13 TeV LHC data to make first measurements of the "underlying" proton interactions at 13 TeV centre-of-mass energy: an important measurement for understanding the intrinsic levels of particle activity induced by these record-breakingly high-energy collisions. Longer term, I have been contributing to searches the Higgs boson decaying to two b quarks -- a very difficult process to look for, since there are many known ways to produce collision events that look the same as the Higgs decay. I have been working with students and researchers in Glasgow to understand and improve the understanding of such "background" events, and to reduce their impact by improving both experimental methods and background process simulation. In particular we have been working on measurement of bottom-quark jet properties in LHC Run 2 and on methods to "tag" such jets, and I created a workshop series on this "heavy quark" production to connect relevant theorists and experimentalists.

Separately, I have been developing tools which help to make sure that our simulations are as good as they can be, and to interpret LHC data more adventurously. These include the Rivet toolkit, which is the main computational archive of LHC data analysis logic, which in the last year I extended to be much more suitable for beyond-Standard-Model search preservation, and the Professor system which improves the data description of complex simulations: we have recently made use of this to tie down new physics models interacting with top quarks.
