Dr. Robert Tilling, Scientist Emeritus with the United States Geological Survey (USGS) Volcano Science Center. In 2004, Bob “officially” retired after a 42-year career as a volcanologist with the USGS, but continues his volcano studies as well as occasional consulting work on volcanic hazards. He is the author of 8 books about volcanoes and earth processes, as well as numerous technical papers. He has advised foreign governments, studied volcanoes across the globe, and managed various scientific teams and organizations within the USGS. During the reawakening and eruption of Mount St. Helens in 1980, he was in charge of USGS studies. In recent decades, he also has been actively involved in educational outreach and co-authored USGS’ all-time best-selling map, “This Dynamic Planet,” a world map about plate tectonics specifically intended for teaching purposes. Bob is a member of the Geologists of Jackson Hole, and regular visitor to the Valley where he and his wife Susan spend part of each summer with their daughter Karen Coleman (VP, Jackson Community Foundation) and family.
