Fields of interest: 

Earthquake Seismology, Geodynamics

My research program focuses on using seismological observations to better understand the crust and mantle dynamics underlying surface deformation, including faulting, magmatism, and the formation and evolution of lithospheric plates.  The tectonic processes that shape the habitable surface environment impact humanity in a number of ways, including by producing major natural hazards such as earthquakes, volcanic eruptions, and landslides, influencing climate and weather over a variety of length and time scales, and establishing the framework for the deposition and storage of major earth resources. In my research, I utilize seismic images of the Earths deep interior to gain a better understanding of the processes that underlie faulting, magmatism, and tectonic deformation. This effort often requires collecting new seismic data in field locations spanning the globe, including from ocean-bottom instruments deployed on the seafloor.
