My research group focuses on the tectonics of convergent margins and the evolution of the continental lithosphere. Research goals are generally centered around identifying and resolving interactions between orogenic magmatism, crustal deformation, and lithospheric dynamics in Cordilleran and collisional orogenic systems. Most research projects are field-based, but we also employ lab-based analytical, experimental, and numerical methods. Please visit the research page to learn more about ongoing research.
