The author is to be commended on his effort. (Energy Sources, August 2004) This book is a giant step forward in describing the development and use of environmental models... (G.F Bennett Journal of Hazardous Materials, 108 March 2004) Author Information"The major focus of Dr. Ralf Seppelt's research is the application of mathematical methodologies for solving environmental problems. He entered this interdisciplinary field upon obtaining a diploma in applied mathematics from the Technical University Clausthal, Germany, in 1994 and with his mater's thesis on socio-ecological models. He continued as a research associate at the Collaborative Research Center ""Water and Matter Dynamics of Agroecosystems"" in Brunswick, where he obtain his doctorate with distinction in science, agroecology, and system analysis in 1997. Over the last few years he has managed several research projects in cooperation with different research institutions as well as industry and with small companies. In 2000 Dr. Seppelt was visiting scientist at the Institute of Ecological Economics, Maryland, USA. Ralf Seppelt has published more than 30 scientific articles and is a reviewer for several international journals. His successful research in the field of environmental science was made possible by his productive interdisciplinary teaching of undergraduate and graduate students. At the TU Brunswick, Dr. Seppelt lectures in computer science, geographic information systems (GIS), theoretical ecological, and numerical environmental modeling."
