Doctor of Philosophy (PhD) in Earth Sciences


The Department of Geosciences offers a master’s in geology and doctorate through the geology and watershed science programs. Both of these programs are internationally renowned, and the completion of a graduate degree is excellent preparation for a career in governmental agencies, private industry, teaching or research.
