Research Area

My interests lie in neutrino theory and phenomenology, with connections to flavour physics and model building. I have a particular interest in the phenomenology of neutrino oscillation experiments and their potential for exploring the lepton sector of the SM and beyond (especially anything related to CP violation, leptonic flavour or neutrino mass mechanisms). However, I find that I am interested in most topics in the neutrino sector, adjacent areas and beyond; do get in touch, if you want to talk about anything.

Teaching

For the 2016/2017 academic year, I will be giving lectures on Neutrino Physics for those studying for an MSc in Particle Theory and on Quantum Theory as part of the third year undergraduate Theoretical Physics 3 module.

Last year I was lecturing Quantum Electrodynamics for the MSc course, and I've been told my name is still on some web pages associated with it. I promise you, I'm not involved.

Publications

I have worked on a number of projects related to neutrino oscillation physics, theories of mass and flavour in the leptonic sector, and the intersection of these two things. Recently, I have been looking at the potential of Fermilab's SBN program to constrain heavy sterile neutrinos (arXiv:1610.08512), the complementarity of DUNE and T2HK (arXiv:1612.07275), and the phenomenology of highly predictive models of leptonic flavour (arXiv:1612.01999). More information to follow soon.

I have a long standing interest in the predictions and testability of models of flavour symmetries, especially via correlations between mixing parameters (so-called 'sum rules'). My collaborators and I have been recently looking at the CSD(n) class of models, which will be well tested over the next decade: arXiv:1612.01999. I have also studied the correlations which can arise from residual symmetries of the group A5 in the presence of a generalised form of CP invariance: arXiv:1503.07543. I am particularly interested in the generality of sum rule predictions, which can often be connected to a very small set of assumptions. These offer a nice way to test (a large chunk of) the paradigm of discrete flavour symmetries at upcoming experiments in a (relatively) model-independent manner. For more information on these, see e.g. arXiv:1410.7573, arXiv:1406.0308.

I also work on more conventional aspects of the long-baseline programme. Around 2013, I worked as a member of the LAGUNA-LBNO collaboration, where I was part of the Physics Task Force which developed and ran the simulations studying the long-baseline physics potential of the design. This work was then built on the following year to perform an analysis of an optimized design, as well as the potential of a dual-baseline facility. In the end, the project was not continued; however, the work (and many of the physicists themselves) became a key input to the DUNE project. See e.g. arXiv:1312.6520 and arXiv:1412.0593

Conference and workshop organisation

I am part of the organizing committee for a topical meeting on neutrino-nucleus interactions to be held 18-20 April 2017 at the IPPP. More details will follow here.

Previously, I was on the organizing committee for NuPhys2016 held on 12-14 December 2016 at the Barbican, London. I was also the anonymous voice manning the conference Twitter account. If you're looking for someone to blame for flooding you feed with neutrinos for three days, feel free to contact me by email.
