I am an observational seismologist who works on problems related to mantle dynamics, with a focus on subduction zone processes, the structure and evolution of continental lithosphere, and the dynamics of the deep mantle. In particular, my group works on the dynamics of subduction systems, using seismic observations and geodynamic models to understand subduction geodynamics, including volatile cycling, the generation and transport of melt, and slab morphology, rheology, and evolution. We also investigate seismic anisotropy and flow in the deep mantle, including the transition zone, uppermost lower mantle, and the core-mantle boundary region. Finally, we are interested in the structure, evolution, and deformation of continental lithosphere, both in regions of present-day tectonic activity (such as Cascadia and western South America) and in regions that have been affected by subduction and continental breakup in the past (such as eastern North America). My research encompasses a substantial field component, with recent or ongoing seismometer deployments in the Pacific Northwest, Peru, the central Appalachian Mountains, Newfoundland, offshore eastern North America, and New England.
