Our research primarily focuses on deep continental crust, specifically the physical and chemical processes associated with rock and mineral deformation. Generally, I can group much of my research efforts into the following themes: 1) understanding crustal processes through the study of exposed high-pressure granulite terranes and lower crustal xenoliths, 2) metamorphic & structural controls on rheology & crustal seismic anisotropy, and 3) accessory mineral petrogenesis & in situ geochronological techniques. Some more specific areas of active research are highlighted below.
