Richard Tollo is a geologist specializing in petrologic and geochemical studies of Precambrian rocks of igneous and metamorphic origin occurring in the Blue Ridge geologic province of the southern Appalachians. He specializes in using integrated studies involving field mapping, petrologic studies, and applied isotopic geochronology to improve understanding of the petrogenesis of ancient magmatic systems and to elucidate tectonic processes that affected the Blue Ridge during the Precambrian. He has published multiple research papers concerned with the petrologic evolution and tectonic significance of Precambrian rocks of the Blue Ridge province, and is the lead editor of two Memoirs concerning the geology of the regional Grenville and Appalachian orogens published by the Geological Society of America. Throughout his career, he has emphasized involvement of undergraduate students as research collaborators, making it possible for students to become regularly engaged in all levels of the research process. Many of these students have been co-authors with him of major research papers and field trip guides. Professor Tollo teaches courses designed for all levels of undergraduate education including Physical Geology, Mineralogy, Igneous and Metamorphic Petrology, Geological Field Methods, Volcanology, and Field Experience in Volcanology which involves an 8-10 day summer field exercise in volcanology that focuses on an alternate-year basis on either the volcanic geology of Yellowstone National Park and vicinity or the Cascade magmatic arc located in central and southern Oregon. He is currently writing a book concerning the volcanic evolution of the Oregon Cascades and the contributions made by researchers working in the region during the past six decades. He has been repeatedly recognized for his dedication to teaching, receiving, among others, the Trachtenburg Award for Excellence in Teaching from GWU, Professor of the Year Award from the GWU Department of Athletics and Recreation (twice), and the US Professor of the Year in the District of Columbia Award from the Carnegie Foundation for the Advancement of Teaching and the Council for Advancement and Support of Education. He is the former Director of the Geological Sciences Program where he continues to teach today.
