I’m interested in the structural evolution of the Earth’s crust at a variety of scales. I pursue questions about mountain building, climate and tectonic interactions, surface processes, and landscape evolution in a variety of tectonic settings. My primary research tool is seismology, ranging from high-resolution (<5 m) subsurface imaging in a marine setting to land-based crustal scale refraction seismology. My students and I often blend seismological imaging with stratigraphic and structural interpretation and modeling as well as complementary geophysical modeling using gravity and magnetics.

Examples of recent work include the integration of ocean drilling and seismic reflection data to investigate the role of glacial advance-retreat cycles in modulating fluid flow and deformation in the northeastern Alaska-Aleutian subduction zone; utilizing data from a dense array of ~800 seismometers to image the Socorro Magma Body, the world’s second-largest actively inflating magma body; determining velocity structure across the eastern North American margin to investigate the interplay between tectonic extension and magmatism during the early stages of continental rifting.
