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.
