Associate Director
Dr Wes Armour is an interdisciplinary research scientist based at the Oxford e-Research Centre and a visiting scientist atDiamond Light Source.
His research interests focus on applying techniques from GPU computing, computational physics and applied mathematics to a range of fields which include radio astronomy, protein crystallography, microtomography and condensed matter physics. Current projects relate to:
- The MOTIVATE project: Real-time signal and image processing for LOFAR and SKA on GPUs;
- The ARTEMIS project: Real-time detection of pulsars and radio transients;
- Live ARTEMIS results from LOFAR UK can be found here!
- Application of Lattice Field Theory to simulate Graphene on clusters and GPUs;
- Lattice Field Theory simulations of QED3 and consequences for spin liquids and cuprate superconductivity;
- Implementation of X-ray microtomography for use on protein crystallography beamlines;
- Real-time model based dose calculations and radiation damage corrections for protein crystals;
- Absorption corrections for X-ray diffraction data collected from protein crystals;
- Statistical techniques for merging multiple crystal datasets.
