William H. Craddock, Ph.D.
William Craddock is a Research Geologist with the USGS Geology, Energy & Minerals (GEM) Science Center in Reston, VA.
William's interests include tectonics and the economic geology of sedimentary basins. He employs a broad range of techniques in order to address specific research questions, including geologic mapping, stratigraphic and structural analysis, geochronology, thermochronology and geomorphology. William obtained his Ph.D. in geology from Penn State University in 2011, his M.S. in geology from the University of California at Santa Barbara in 2006, and his B.S. in environmental geology from the College of William and Mary in 2004. He is a member of the Geological Society of America, the American Association of Petroleum Geologists, and the Geological Society of Washington D.C.
