Todd Rayne
Joel W. Johnson Family Professor of Environmental Science Emeritus (retired)
Todd Rayne's current research involves using environmental tracers numerical modeling to study the impacts of urbanization on ground water flow systems. He also is involved with modeling ground water flow through fractured aquifers and wellhead protection studies. He is the author of two solution manuals for hydrogeology textbooks and has published papers in Hydrogeology Journal, Nordic Hydrology and Northeastern Geology and Environmental Science. He received his doctorate in geology from the University of Wisconsin-Madison. Before that he worked in the petroleum and environmental consulting industries.
