The "Crustal Geophysics" research group studies the tectonics and geodynamics of the lithosphere, typically focussing on continental lithosphere that is currently or recently deforming and evolving. We use controlled-source reflection and refraction seismology on land and at sea, and a wide range of passive seismological analyses (shear-wave splitting, receiver function analysis, surface-wave inversion) as necessary to address the chosen problems. Recent and ongoing areas of investigation are the Himalaya-Tibet orogen, extensional and magmatic provinces in the western U.S.A., the East Africa Rift, and electromagnetic monitoring of the San Andreas Fault.
