I am interested in the physical properties of solids under high pressure, which I study with x-ray diffraction and x-ray diffuse scattering in combination with ab initio electronic structure calculations. 

• Pure Elements: Numerous elements have been discovered to adopt high-pressure phases with extremely complex crystal structures. I have studied the physical properties and the mechanisms that stabilise exotic elemental phases.
• Thermoelectric Materials: I am interested in understanding why some thermoelectric materials show dramatic enhancements of their properties at high pressure, so as to help create better-performing thermolectrics. 
• Technique development: I am interested in developing and adapting the analysis of x-ray diffuse scattering data from single crystals for determining the phonon dispersion relations of materials under high pressure.
