Interests and Expertise

Dr. Eric Portenga is a geomorphologist from west Michigan specializing in understanding the how our planet’s surface evolves over historical and geological timescales. After completing his B.S. in Geological Sciences at the University of Michigan, Dr. Portenga received his M.S. in Geology from the University of Vermont, and then he completed a joint-Ph.D. in Earth Science at the University of Glasgow in Scotland and Macquarie University in Australia. He returned home to Michigan for a Postdoctoral Research Fellowship at the University of Michigan. Dr. Portenga has studied long-term landscape evolution of the Appalachian Mountains, landscape response to human land-use practices in Australia throughout the Holocene, uplift and erosion of the Santa Monica Mountains in California, deglaciation in Greenland, and erosion in Bhutan and South Africa. He looks forward to sharing his knowledge and working with colleagues and students at EMU as well as expanding his research to include untangling parts of Michigan’s glacial history.
