Research interests

Ryan’s research interests are focused on using earthquake seismology to study tectonics. He is specifically interested in crustal and upper mantle structure, subduction zone processes, and seismic anisotropy. Much of his work focuses on studying the impact of subduction on the tectonic evolution of the North and South American Cordillera.
