About the Author
Trevor M. Letcher is Emeritus Professor of Chemistry at the University of KwaZulu-Natal, Durban and a Fellow of the Royal Society of Chemistry. He is a past Director of the International Association of Chemical Thermodynamics and his research involves the thermodynamics of liquid mixtures and energy from landfill. He was awarded the South African Chemical Institute's Gold medal in 1999 and in 2000 he was awarded the South African Gold medal by the South African Association for the Advancement of Science. He has published over 250 papers in peer review journals and has edited, co-edited and written eleven books in his research and related fields. His latest books include Unraveling Environmental Disasters (2012), Materials for a Sustainable Future (2012), Waste (2011), Heat Capacities (2010), Climate Change (2009) and Future Energy (2008). Dr. Daniel A. Vallero is an internationally recognized expert in environmental science and engineering. His four decades of research, teaching and professional experience in hazardous waste engineering and management have addressed a wide range of human health risk and ecological issues, from global climate change to the release of hazardous wastes. His research has advanced the state-of-the-science of air and water pollution measurement, models of potential exposures to chemicals in consumer products, and environmental impact assessments. He established the Engineering Ethics program and is a key collaborator in the Responsible Conduct of Research Program at Duke University. These programs introduce students, from first-year through PhD, to the complex relationships between science, technology and societal demands on the engineer. The lessons learned from the cases in this book are a fundamental part of Duke's preparation of its future engineers to address the ethical dilemmas likely to be encountered during the careers of the next generation engineers.Dr. Vallero received a bachelor's degree from Southern Illinois University, a Master of Science in City & Regional Planning from SIU, a Masters in Civil & Environmental Engineering (Environmental Health Sciences) from the University of Kansas, and a PhD in Civil & Environmental Engineering from Duke.
