Research Interests: Dr. Isbell is a clastic sedimentologist and sequence stratigrapher who works with glacial, glaciomarine, fluvial, deltaic, shallow marine and glacially influenced deep marine sediment and sedimentary rocks deposited in foreland, rift, piggyback, and cratonic basins. He currently works on rock exposures in Antarctica, Argentina, Aus- tralia, South Africa, the Falkland Islands, the Russian Far East (Siberia), the western United States, the Appalachian Mountains, and in Wisconsin. His work focuses on understanding environmental changes that occurred during critical intervals in Earth History. These include (1) the late Paleozoic Ice Age (LPIA), (2) the ensuing Permian- Triassic greenhouse (359 to 199 million years ago) and (3) the transition from the Cretaceous to the Tertiary prior to and following the end-Cretaceous extinction event (145 to 55 million years ago).
