Mineralogy and Properties of Earth Materials:

Exploring the relationship between atomic-level structure and the properties of earth materials, through experiments and modelling. Measurement of the atomic-level structure and dynamics of minerals, glassy and molten silicates and oxides, and ceramics using nuclear magnetic resonance (NMR), with the goal of understanding and predicting their thermodynamic and transport properties. The problems addressed are tied to large-scale processes in geology and geophysics, as well as to those in high-tech industries. Among the former are the mechanisms of viscous flow in magmas and of solid solution in minerals from the crust to the lower mantle; among the latter are the optimization of glasses for flat screen computer displays and optical data transmission and of oxide ceramics for fuel cells.
