Research Interests

I am a structural geologist interested in unraveling the tectonic history of mountain belts.  My research interest requires integrating structural geology with other disciplines of geology such as geochronology/thermochronology, metamorphic petrology, stratigraphy, or geomorphology.  This interdisciplinary approach facilitates the determination of timing of events, the temperature and pressure conditions of structural processes, the environments of deposition, and the seismic risk of active structures.  My interests span the time scale from active tectonics in New Zealand to Proterozoic events in Namibia.  International geology research is necessarily coupled with attention to local cultures and the environment and is optimally done in collaboration with local scientists.

Classes Taught

Structural Geology, Tectonics of Mountain Belts, Tectonics and Geomorphology, Tectonics and Climate, Plate Tectonics, Physical Geology
