Dr. Shipley has a number of research interests that primarily involve understanding the subduction processes occurring at converging plate margins. Subduction zones are regions of the earth where one plate passes beneath another creating earthquakes and spawning volcanic activity. Mass transfer from one plate to the other often produces large deformed sedimentary rock wedges. Much of his work has involved investigating the deformation of these wedges and their spatial and temporal evolution.
