Sean is a research professor of geoscience at the University of Texas, Austin. He is interested in tectonic-climate interactions, the role of catastrophism in the geologic record and marine and planetary geophysical imaging at nested resolutions. His current projects include tectonic and glacial interactions in Alaska, geohazards and margin evolution of subduction and transform faulting in Alaska, Sumatra, New Zealand, and Japan, and the geologic processes, environmental effects, and habitability of the Cretaceous-Paleogene Chicxulub meteor impact.
