Jonathan is in 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. Current research covers decays of particles containing heavy bottom or charm quarks, as well as kaon physics.
Teaching covers electromagnetism and a dissertation course for undergraduates and quantum field theory for postgraduate students. He is a Senior Tutor for Physics and Astronomy and chair of the postrgraduate Special Considerations Board for the Faculty of Physical Sciences and Engineering.

My research is in particle physics with particular interest in lattice QCD supercomputer simulations for flavour physics and wider interests in flavour physics phenomenology. Current research covers 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.

Add up to 5 research interests. The first 3 will appear in your staff profile next to your name. The full list will appear on your research page. Keep these brief and focus on the keywords people may use when searching for your work. Use a different line for each one.
In Pure (opens in a new tab), select ‘Edit profile’. Under the heading 'Curriculum and research description', select 'Add profile information'. In the dropdown menu, select 'Research interests: use separate lines'.
Update this in Pure (opens in a new tab). Select ‘Edit profile’ and then ‘Curriculum and research description - Current research’.
Describe your current research in 100 to 200 words. Write in the third person. Include broad key terms to help people discover your work, for example, “sustainability” or “fashion textiles”.
Research Council funded projects will automatically appear here. The active project name is taken from the finance system.
Public outputs that list you as an author will appear here, once they’re validated by the ePrints Team. If you’re missing any outputs that you’ve added to Pure, they may be waiting for validation.
Current PhD Students
Contact your Faculty Operating Service team to update PhD students you supervise and any you’ve previously supervised. Making this information available will help potential PhD applicants to find you.
I have taught many of Physics and Astronomy's first and second year core modules. Currently I teach PHYS2001 Electromagnetism and coordinate PHYS6009 Dissertations. I also teach in our PhD student training programme, currently running the third Quantum Field Theory course for students from Southampton and other universites in the SEPnet group of physics departments in South East England.

External roles and responsibilities
These are the public-facing activities you’d like people to know about.
This section will only display on your public profile if you’ve added content.
You can update your external roles and responsibilities in Pure (opens in a new tab). Select ‘+ Add content’ and then ‘Activity’, your ‘Personal’ tab and then ‘Activities’. Choose which activities you want to show on your public profile.
You can hide activities from your public profile. Set the visibility as 'Backend' to only show this information within Pure, or 'Confidential' to make it visible only to you.
I am in 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 have been 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). Currently I serve on STFC's IRIS Resources Scrutiny Panel and the UKRI ARCHER eCSE distributed software engineering support panel.
