Assistant Professor


I joined the Department of Geography and Geology at SHSU in the Fall of 2013 after working as a research scientist for the past ten years at the University of California–Davis (UCD) and for the previous eight years at Texas A&M University in the Ocean Drilling Program (ODP) and its successor the Integrated Ocean Drilling Program (IODP). Much of my research focuses on extracting information about variations in Earth’s magnetic field, formation and evolution of oceanic crust, and environmental and climate change from drill cores collected from the ocean basins. I also have been involved in dating sedimentary sections using magnetostratigraphy, relative geomagnetic paleointensity, and astrochronology, and in investigating the petroleum potential of rift basins and the magnetism of the early solar system. I have participated on 12 scientific ocean drilling cruises, which sampled sediments and rocks deep below the seafloor in the Caribbean Sea, the North Atlantic, the equatorial and north Pacific, the Arctic Ocean, Baffin Bay, and off the coast of West Antarctica. In addition, I spent three months on Ross Island in Antarctica working with the Antarctic Geological Drilling (ANDRILL) program. In the classes I teach at SHSU, I attempt to convey some of the vast knowledge gained from these large-scale studies, as well as the thrill of participating in scientific ventures around the globe.
