Dr. Ryan Kerrigan graduated from Bridgewater State University with a B.S. in Geology and B.A. in Chemistry before attending the University of Minnesota for his M.S. in mineralogy/petrology. Dr. Kerrigan moved to the University of Maryland to complete his Ph.D. in experimental petrology. After his Ph.D., Dr. Kerrigan spent four years in the private sector completing environmental site assessments and remediation projects where he earned his Professional Geologist’s license. In the Fall of 2014 Dr. Kerrigan joined the faculty at University of Pittsburgh at Johnstown and in 2020 became an Associate Professor of Geology and Departmental Coordinator for the Energy and Earth Resources Department. Dr. Kerrigan’s current research interests include: pedagogy in the geological sciences, hydrothermal alteration of ultramafic/mafic rocks, provenance of orogenic emplacement formations, and geology of the central Appalachian Piedmont.
