Dr Wes Armour is an interdisciplinary research scientist based at the Oxford e-Research Centre and a visiting scientist at Diamond 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;
• 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.
