Dick Luthy is the Silas H. Palmer Professor and former chair of the Department of Civil and Environmental Engineering, and Senior Fellow in the Woods Institute for the Environment at Stanford University. His area of teaching and research is environmental engineering and water quality. His research interests include physicochemical processes and applied aquatic chemistry with application to water reuse and management of contaminates in sediment. Current projects address the role of natural systems to enhance water quality and the potential for water reuse to benefit ecosystem habitats and urban aesthetics. His research emphasizes interdisciplinary approaches to understand the environmental behavior and availability of organic contaminants and the application of these approaches to the control of contaminant bioavailability and the improvement of water and sediment quality. Dick Luthy is a past chair of the National Research Council's Water Science and Technology Board, and a former President of the Association of Environmental Engineering and Science Professors. He is a registered professional engineer, a Board Certified Environmental Engineer, and a member of the National Academy of Engineering.
