Research
My ATLAS research is focused on studies of the Higgs boson and searches for new physics beyond the Standard Model (BSM). With the run-1 ATLAS data I made significant contributions to the search for the Higgs boson, discovered in 2012, particularly via its decay to a pair off b-quarks. Following the discovery, I was instrumental a wide range of searches for additional Higgs bosons (such as a heavier CP-even Higgs, a CP-odd Higgs or a charged Higgs) and spearheaded the first run-2 ATLAS Higgs searches as ATLAS BSM Higgs subgroup convener. I have subsequently utilised the Higgs boson as a new-physics probe. With the early 13 TeV data, I played a major role in the novel search for dark matter recoiling against a Higgs boson. As ATLAS Exotics Diboson and Multilepton (DBL) subgroup convener, I oversaw the searches for new diboson resonances with the 2015+16 data, probing uncharted masses. I subsequently led the search for the as-yet-unobserved Higgs pair production, which is a fundamental test of the Higgs mechanism, in the bbtautau channel, establishing the world's best limit on the SM di-Higgs cross section. From 2018-2020, I lead the ATLAS BSM search programme as Exotics Working group convener, overseeing over 500 international physicists. Besides physics analysis I have contributed significantly to ATLAS track reconstruction software and the identification and calibration of jets originating from b-quarks; I currently contribute to the production database for the ITK silicon tracker replacement for the High-Luminosity LHC upgrade. Nationally, I was ATLAS UK Physics Coordinator from 2020-2022 and I am currently Liverpool ATLAS Team Leader.
I joined the FASER experiment to search for long-lived particles (LLPs) downstream of ATLAS in 2020, where I have published searches for dark photons and axion like particles (ALPs) probing previously unexplored phase space. From 2022-2024, I was FASER Physics Coordinator, where I wa responsible for defining and overseeing the physics program of the FASER Experiment, coordinating the work of 90+ international physicists across different analysis teams, leading to timely delivery of the first FASER physics publications, which (in addition to the above LLP searches) provided the first direct detection of collider neutrinos that open a new avenue to study the Universe. In addition to physics analysis, I have contributed significantly to the simulation and digitisation of the scintillators and EM calorimeter. Looking forward, I am studying the physics potential of the proposed CERN Forward Physics Facility (FPF), in particular the optimisation of the tracking detector.
I have recently joined the newly-approved SHiP experiment at the CERN SPS as an associate member, investigating ways Liverpool can contribute.
