Research Interests

As a metamorphic geologist in the Structure, Tectonics, And Metamorphic Petrology (STAMP) research group, I am interested in using metamorphic rocks to reconstruct the chemical and physical processes that drove metamorphism in continental and oceanic crust and that eventually returned these rocks to the Earth’s surface. Ongoing collaboration with Christian Teyssier (UMN) and Patrice Rey (U Sydney) focuses on the dynamics of partially molten crust, including the trajectory of flow (vertical, lateral), magnitude of flow, driving mechanisms, and the thermal and mechanical consequences for continental evolution. I am also currently directing a large, multidisciplinary research project in Turkey (CD-CAT, Continental Dynamics-Central Anatolian Tectonics), to investigate the mantle-to-surface dynamics during the development of a tectonic escape system. I have also long been interested in metamorphic textures; for example, microstructures in garnet and the interaction of deformation and metamorphism in different tectonic settings, from the scale of mineral grains to mountain belts. Major field sites are in the North American Cordillera, Turkey, France, and Norway.
