Research and Academic Interests:

Structural Geology and Tectonics. Research interests in field and analytical studies of ductile rock deformation; growth and assembly of Proterozoic continental lithosphere in North America; and studies of the dynamic interaction of deformation, pluton ascent, emplacement and metamorphism. Studies of uplift history of the Western U.S., including dynamic topography and mantle-to-surface interactions.
