Research Interests

My research is in the area of structural geology focused on studying strain, deformation fabric formation, and rheology in naturally deformed rocks. I primarily study shear zones, tectonites including deformed conglomerates, and granite emplacement fabrics at a variety of scales. Most of my work combines field studies with other techniques like petrographic studies, electron backscatter diffraction (EBSD, to measure crystallographic orientations in rocks), FTIR (to measure water content in deformed rocks), mathematical modeling, or magnetic fabric studies. Over the last several years, I’ve had the opportunity to study rocks in Spain (Catalonia, Andalusia), Scotland (NW Highlands, Islay), Canada (Ontario, Nova Scotia), and the USA (Wisconsin, Utah, California, Minnesota). Students are collaborators on most of my research projects.
