The focus of our research is on fundamental issues of structure and dynamics in crystalline, glassy, and molten silicates and oxides. Our goal is to relate measurements of atomic-scale processes to macroscopic properties of interest to the Earth sciences (including mineralogy, igneous and metamorphic petrology, volcanology and geochemistry), materials science (glasses, ceramics, and thin films), and physical chemistry. The major research tool in our group is Nuclear Magnetic Resonance (NMR) spectroscopy, which is especially useful for disordered crystalline and amorphous materials. We often collaborate in studies of high pressure minerals and melts.
