Dorothy Merritts and Robert Walter, Franklin and Marshall College

Presentation Title: What to do about these dammed streams? A New Restoration Design for the Appalachian Piedmont

They will be hosted by GES faculty member Missy Eppes.

Professor Dorothy Merritts (B.Sc. Indiana University of Pennsylvania, M.Sc. Stanford University, Ph.D. University of Arizona, is a geologist with expertise in streams, rivers, and other landforms, and on the impact of  geologic processes and human activities on the form and history of Earth's surface.  In the western United States, she conducted research on the San Andreas fault of coastal California, and her international work focuses on fault movements in South Korea, Indonesia, Australia, and Costa Rica. Her primary research in the eastern United States is in the Appalachian Piedmont, particularly in southeastern Pennsylvania and northern Maryland, where she is investigating the role of human activities in transforming the upland woodlands and valley bottom wetland meadows of Eastern North America to a predominantly agricultural and mixed-industrial/urban landscape since European settlement.  She is a professor in the Department of Earth and Environment at Franklin & Marshall College in Lancaster, Pennsylvania.  In 2004-2005 she was the Flora Stone Mather Visiting Distinguished Professor at Case Western Reserve University in Cleveland, Ohio.  In 2011-2012 she was appointed the Cox Visiting Professor at Stanford University.  She is the author of two textbooks and more than 50 scientific articles, and the editor and contributing author for numerous scientific books.

Professor Robert Walter (B.A., Franklin and Marshall College; Ph.D. Case Western Reserve University, is a geologist, geochemist and geochronologist. He has conducted field research in East Africa, North America, New Zealand and Asia, and is a leading expert on timescale calibrations and the geological context of human antiquity. He was elected a Fellow of the California Academy of Science in 1995. In 2002-2003 he was awarded a Diplomacy Fellowship by the American Association for the Advancement of Science, through which he was a science analyst for the U.S. Department of State on complex humanitarian emergencies in Africa, the Near East and Afghanistan. In 2004-2005 he was awarded Presidential Fellowship and Visiting Professorship at Case Western Reserve University in Cleveland, Ohio. In 2005 he returned to his alma mater, Franklin and Marshall College, as an associate professor in the Department of Earth and Environment, where his research interests include isotope geochronology, geochemistry, evolutionary timescales, climate change, landscape evolution, and human interactions with the environment. He is the author of over 60 scientific articles and has co-written and co-produced five documentary films.
