Shock compression of minerals
I am currently working on understanding the dynamic compression of geological materials. These studies are relevant to understanding shock metamorphism at impact sites as well as the phase stability of materials at conditions of planetary interiors. The ability to couple established dynamic compression techniques with high-flux x-ray sources gives an in situ probe of structural deformation and phase transitions, at atomic length scales, in materials subjected to dynamic loading.


Nuclear Resonant Scattering
Activation barrier measurements for charge hopping in mixed valent oxides give fundamental insights into the correlation between electronic carriers and mobile ions in battery cathode materials. Nuclear resonant scattering and synchrotron x-ray diffraction allow for the study of the local dynamics of materials that exhibit thermally activated polaron hopping and reveal details concerning the correlation between electronic and ionic mobility.
