Dr Wes Armour is Centre Director and leads the Scientific Computing Group. Dr Armour has an MPhys degree in Fundamental Particle Physics and Cosmology and a PhD in Lattice Gauge Theory (the computational description of the strong nuclear force).

His research interests are strongly focused in Scientific Computing, specifically the use of HPC and many-core technologies to answer scientific problems or to have impact in people’s day-to-day lives. Topics of work are centred on modelling and simulation, Digital Signal Processing (DSP), HPC/many-core and real-time computing for Big Data / Data Science.

Current projects at the Centre relate to:

  • The Square Kilometre Array (SKA) project, an international effort to build the world's largest radio telescope;
  • Astro Accelerate a many core accelerated software package for processing time domain radio-astronomy data;
  • OpenFOAM improving Computational Fluid Dynamics codes;
  • C4X Discovery Ltd increasing speed of drug discovery;
  • The ARTEMIS project: Real-time detection of pulsars and radio transients;
  • Application of Lattice Field Theory to simulate Graphene on clusters and GPUs.

Past Projects:

  • The MOTIVATE project: Real-time signal and image processing for LOFAR and SKA on 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.
