Dynamic Compression 
I use dynamic compression to study the behavior of materials at high pressures and temperatures. These studies are relevant to understanding shock metamorphism in samples from natural impact sites and characterizing the phase stability of materials at conditions of planetary interiors. By coupling established dynamic compression techniques with pulsed x-ray sources this work provides real-time information about atomic-level deformation and phase transitions for materials subjected to dynamic loading.




Nuclear Resonant Scattering
I use nuclear resonant scattering to study both lattice dynamics and the valance and spin state of iron-bearing materials. This includes studies carried out at variable temperature and pressure conditions for systems ranging from next-generation battery materials to materials of geophysical importance. Experiments are carried out using both conventional Mössbauer spectrometry and synchrotron methods and use sample environments including diamond-anvil cells, cryostats, laser-heating, and restive furnaces.
