Interaction of planetary materials with gases and the role of these processes in understanding the evolution of planetary environments and surfaces. These studies are relevant to gas sequestration, reactions at and beneath volcanoes and in ore deposits, and reactions on the surface of Mars and in the early solar system.
Effect of volatile elements, pH and oxidation/reduction on materials at high and low temperature.
Analysis of materials - especially novel techniques for analyzing light elements, multivalent elements and trace elements - to better constrain past environmental processes.
