Microstructural Kinetics
My principal research relates to the physics and chemistry of complex materials inorganic glasses, glass forming liquids and amorphising solids. I have also worked on amorphous semiconductors like arsenic and silicon, and on chalcogenide glasses. Often my research is underpinned by instrument development, such as combining X-ray techniques and also neutron scattering, which have been recently applied to study polyamorphism and liquid-liquid transitions in materials at high temperatures and pressures. Emerging interests include the mechanical properties of materials as expressed through Poisson’s Ratio – exploring this metric in the context of atomic structure, phase transitions, and also the rheology of the liquid from which solids condense and into which they melt.
