Interests and Expertise

Dr. Eric Portenga is a geomorphologist from West Michigan specializing in understanding how our planet's surface evolves over historical and geological timescales. After completing his BS in Geological Sciences at the University of Michigan, Dr. Portenga received his MS 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 Eastern Michigan University as well as expanding his research to include untangling parts of Michigan's glacial history.
