I am a high energy physicist, specialising (as my job title might suggest) in neutrino physics. In particular I am interested in understanding the properties of these fundamental particles - neutrino oscillations, the origin of neutrino mass and whether neutrinos violate the CP symmetry of nature.
I currently work on the T2K and Hyper-K experiments. These are current (T2K) and future (Hyper-K) long-baseline neutrino experiments situated in Japan. Both experiments involve creating a beam of muon-flavour neutrinos at the east coast of Japan and shooting it to the west coast, where it is observed by multi-kilo-tonne water Cherenkov detectors.
T2K began taking data in 2009 and established that muon neutrinos do oscillate into electron neutrinos, and at an appreciable rate. This large rate means that it is possible to search for neutrino CP violation by comparing the rate of muon-to-electron flavour oscillation for neutrinos to that of antineutrinos. If there is a difference, this could explain why we exist in a matter-dominated universe.

I am currently the Head of Experiment for the Radioactivity experiment in the 2nd Year Undergraduate Teaching Laboratory. The lab has been updated for 2019 with brand new equipment, new data acquisition software and (hopefully) new radioactive sources. The aim of the lab is to introduce students to a realistic experimental setup, where the data pass through many stages between the initial sensitive instrument and the final analysis. The lab encourages students to think about what is happening at each stage, to assess the likely impact of systematic uncertainties and to learn a bit about the interaction of particles with matter.
I will also be teaching Computational Physics alongside Prof. Yoshi Uchida. Computational Physics is a third-year option course which goes through the basic (and more complicated) algorithms that under-pin almost all scientific computing. It also includes a substantial amount of practice in both programming and presenting the results from these algorithms.
