My research interests in structural geology and tectonics range from mid-crustal flow to active tectonics. A common theme to my research is the spatial and temporal variability of strain partitioning at different scales and levels in the crust. I characterize the transition from melt-present flow to solid-state fabric development and quantify the kinematic evolution of high strain zones. I am interested in granite emplacement mechanisms, timing and duration of melting and the relationship between melting and rheology of the crust. Through international collaborative research, I integrate my field-and lab-based specialties with thermochronology, geochronology and isotopic geochemistry to test the evolution of orogenic systems.
