Research interests

Origin and evolution of planetary interiors and surfaces. Effect of volatiles, pH and oxidation/reduction on materials at high and low temperature. Analysis of astromaterials - especially novel techniques for analyzing light elements, multivalent elements and trace elements - to better constrain past environmental processes. Field analogs for Mars, Europa, Callisto, and Ganymede.

Researcher's projects

My current research focuses on the origin and evolution of planetary surfaces; and the roles of volatiles, pH, and gases on minerals and melts/glasses at high and low temperatures.  I am particularly interested in the interface between volcanic and sedimentary rocks and the atmosphere.  Our group uses techniques in micro-analysis (especially infrared spectroscopy), performs high and low temperature experiments, and examines geology in the field and applies that to other planets like Mars.
