Teaching 2010/2011
Research
Low energy Quantum Chromodynamics using computer simulation, and particularly matrix elements of hadrons that are required to constrain fundamental parameters of the standard model and search for physics beyond the standard model. I believe my publications represent the best constraints on Vus and BK which enter the famous unitarity triangle.
Subtopics: Kaon matrix elements - BK, Kl3 , K->pi pi. Non-perturbative renormalisation of Lattice operators. Chiral lagrangian. Hadron spectrum and decay constants. Electromagnetic effects.
I am a member of the RBC-UKQCD collaboration, and collaborate with Columbia University, Southampton, Brookhaven National Laboratory, RIKEN Brookhaven Research Center, University of Virginia, University of Connecticut.

High performance computing
I worked (a lot) on the development of the QCDOC special purpose supercomputer Edinburgh/Columbia/Riken/IBM, simulation testing, operating system, debug and shakeout. I wrote the bulk of the physics simulation assembly code run on the machine. A 14,000 and 10Tflop/s node QCDOC that I co-developed operated in Edinburgh from 2004 until 2009, performing the bulk of UKQCD’s calculations.
I am presently working (a lot) in collaboration with IBM T J Watson Research Center and Columbia University designing the chip for UKQCD’s next major facility, expected to be around 800Tflop/s and for which we have just been awarded a £3.3M grant. This prototype is expected to become an IBM product.
