About
Jonathan maintains links to the high energy theoretical physics group in Physics and Astronomy, with research interests in lattice quantum chromodynamics simulations on supercomputers for application to particle physics. Research covers decays of particles containing heavy bottom or charm quarks, as well as kaon physics.
I taught many of Physics and Astronomy's first and second year core modules. I was Director of Programmes and Senior Tutor for Physics and Astronomy, and chaired the postrgraduate Special Considerations Board for the Faculty of Physical Sciences and Engineering.

Current research
My research is in particle physics with particular interest in lattice QCD supercomputer simulations for flavour physics and wider interests in flavour physics phenomenology. Research includes semileptonic decays of hadrons containg heavy bottom or charm quarks, K pi scattering and rare kaon decays. These calculations test our understanding of QCD contributions to decay processes and allow us to test the Standard Model of particle physics, revealing (we hope) clues to New Physics beyond it.

Teaching
I taught many of Physics and Astronomy's first and second year core modules and coordinated Dissertation and Project modules. I also taught in our PhD student training programme, covering Quantum Field Theory and Group Theory.
Biography
I maintain links to the Theoretical Particle Physics research group, with particular interest in lattice QCD supercomputer simulations for flavour physics and wider interests in flavour physics phenomenology. I came to Southampton in 1991 after a PhD at Harvard University and postdoctoral positions at the Rutherford Appleton Laboratory and the Fermi National Accelerator Laboratory (FNAL), Chicago.
I was Head of Department (2015-2019) and was previously in charge of undergraduate teaching as Director of Programmes. I have served as external examiner for theoretical physics degree programmes at the University of Edinburgh and Trinity College Dublin.
I am a past chair of the CERN Computing Resources Scrutiny Group, scrutinising the computing requirements of the four main LHC experiments. I have also chaired STFC's GridPP Oversight Committee, monitoring the UK's contribution to the worldwide LHC computing grid (wLCG). I served on STFC's IRIS Resources Scrutiny Panel and the UKRI ARCHER eCSE distributed software engineering support panel.
