Fields of interest:
earthquake seismology, tectonics, lithospheric structure, subduction zones
My work centers on using earthquake seismology as a tool for investigating the processes by which continental and oceanic plates interact and evolve at subduction zones. I'm currently using converted body waves, surface waves, and ambient noise to constrain lithospheric structure and seismic velocities in active subduction zones on the eastern Pacific margin and beneath the extinct arc of the Coast Mountains of western Canada.
