My research interests are in using x-ray diffraction and scattering to investigate the behaviour of simple materials to extreme pressures and temperature.  I am a frequent user of synchrotron light sources in the UK, Europe and the US, where we have developed techniques to collect and analyse diffraction data from both polycrystalline and single-crystal samples.  Most recently, my research interests have moved to the use of dynamic compression technicques, utilising powerful laser sources and x-ray lasers, to push strctural studies of matter well beyond the current limits of static compression science.
