I arrived at Imperial College in 2004 from Stanford University in California, where I spent some time as a postdoctoral researcher focusing on the KamLAND Experiment, after receiving my PhD at the Massachusetts Institute of Technology as a student of Peter Fisher working at the LEP collider at CERN. Having grown up in Surrey, it has been nice to come back to work near the places that I used to visit as a boy, such as the Museums and the Royal College of Music and other memorable places in the London area.

My research focuses on making new discoveries in particle physics, not by directly searching for previously-unseen fundamental particles, but rather by examining some of the basic particles that we have known about for a long time—namely neutrinos and muons. This often leads us not to work at high-energy particle colliders such as the Large Hadron Collider, but to create custom-designed experiments where we make these particles in huge quantities, and study their—often surprising—properties in detail.

Other Roles

  • Chair of the Collaboration Board and Executive Board member for the COMET Collaboration.
  • Chair of the Publications Board for the T2K Collaboration.
  • Guest Professor of Physics at Osaka University for research in Charged Lepton Flavour Violation.
  • Member of the Institute of Physics Groups Committee.
  • Chair of the Organising Committee for the Flavour Conference in the Rencontres du Vietnam series of conferences at Quy Nhon, Vietnam, jointly with Nazila Mahmoudi. The most recent conference was held in the summer of 2017, and the next one would have been in August 2020, but we have sadly had to postpone it by a year.
  • Founder and Chair of the Organising Committee for the first PhyStat-ν workshop on Statistical Issues in Neutrino Physics, held in May 2016. The most recent workshop in this series was held at CERN from the 23rd of January 2019.
  • Convener at the 2018 edition of the Neutrino Oscillation Workshop, which is held every two years in the southwestern end of Italy, for the "Oscillation parameters: Present" sessions.
  • Member of the Organising Committee for the Neutrino conference in 2016, after Neutrino 2014 in Boston and Neutrino 2012 in Kyoto. Having followed me around the world, the 27th edition of the International Conference on Neutrino Physics and Astrophysics was held at Imperial College London in July 2016.
  • Member of the Scientific Evaluation Committee, Physique subatomique et astrophysique, Agence Nationale de la Recherche


Of my current teaching roles, my most significant is probably that of Head of First Year Laboratory. This course is one of the first occasions at which first-year students experience their new university learning environment, where there is not necessarily a single correct answer to everything and where we encourage independent thinking and teach the skills that help students work in a professional manner, whether they stay in academia or move on to different types of work.

The year of lab work culminates in the First Year Projects, where students can work on open-ended experimental and computational projects on topics of their choosing. To me this is one of the early highlights of the undergraduate course in our department, and school students can come and see the final presentations by our students at our Open Days for GSCE and A-Level students (the links are for the 2014 events).

Since the 2016 academic year, I have been teaching Computational Physics, a third-year optional course in which we teach not just the basic algorithms that underlie scientific computing, but also spend plenty of time practising their use and presentation in the form of projects and reports. I teach this jointly with Dr Mark Scott.
