My research interests

My research has focused on neutrino physics for the past 15 years and I have been fortunate to be involved in a number of world-leading experiments that address the major issues at the frontier of our knowledge in this field (SNO, COBRA, T2K, SNO+). I currently spend 10% of my research time on the T2K experiment: a long-baseline experiment in Japan that is making precision measurements of neutrino oscillation parameters using the world's most powerful man-made neutrino beam and both a near and far detector. I spend 15% of my research time on the HyperK experiment, a proposed future long baseline experiment in Japan to probe leptonic CP violation amongst other physics. I spend the other 75% ofs my time on SNO+: a multi-purpose low background scintillator experiment that aims to address a range of critical issues in neutrino and solar physics 

SNO+ work

SNO+ is uniquely situated to make two major measurements: a search for double beta decay, the golden channel for probing the fundamental nature of the neutrino, which could also provide information on the neutrino mass scale, and a measurement of low energy solar neutrino fluxes, which should not only provide an accurate test of neutrino oscillation theory and probe for possible new physics processes but will also help to reduce uncertainties in solar modelling and our understanding in stellar mechanisms in general. I am co-Analysis Coordinator for SNO+, and as such have a keen interest in all the physics measurements we can make. I am also the Chair Elect of the SNO+ board and PI for the QMUL group. In addition to these responsibilities I am following an exciting research programme, funded by an ERC grant to develop two calibration techniques and improve on aspects of the solar and double beta analyses. In particular, we aim to use an embedded laser system to accurately measure the amount of scattering in the liquid scintillator and improve our understanding of the detector's optical response, and also to develop a beta emitting calibration source using 90Y in order to verify our understanding of the detector response to beta particles.

T2K work

Since joining the T2K collaboration in January 2010 I have been involved in calibrating and understanding the response of the electromagnetic calorimeters, a major part of the near-detector suite build in the UK. In particular I developed and executed the attenuation calibration, using cosmic ray muon tracks to help improve our understanding of the energy response of these detectors. I have also worked on other aspects of calibration, cosmic muon simulations, written code to simulate the cosmic trigger response, and worked on reprocessing test-beam data and Monte Carlo samples. I am responsible for evaluating systematic uncertainties due to event pile-up effects in the near detector and am involved in extending our high-angle sensitivity for cross-section measurements by utilising the electromagnetic calorimeters in the muon event selections. 

HyperK work

I am co-Convener of the international hyperK working group on Near Detectors and have been helping to coordinate efforts on upgrades of the existing near detector suite for T2K, that could be used for HyperK in the future, and also R&D into intermediate water cerenkov detectors at 1-2km from the beam. These detectors in combination should be responsible for reducing the systematics due to flux and cross-section uncertainties to a few percent, required for HyperK CP violation sensitivity. I am also work package manager for Physics and Software on the UK HyperK grant and have been heavily involved in the development of the TITUS intermediate detector proposal. I supervised my PhD student on the development of a fast reconstruction package for TITUS studies and am working with an undergraduate project to optimise the distribution of optical calibration fibres in the hyperK far detector.
