Brief Biographical Sketch

J. W. SKILES is a Research Scientist in the Ecosystem Science and Technology Branch at NASA Ames Research Center (ARC). He has conducted studies in terrestrial ecosystem modeling, world grasslands, Arctic, arid, and semiarid ecosystems, and African grazinglands. He received a B.S. in biology with a minor in chemistry from the University of Redlands (1969), an M.S. in botany from the University of Idaho (1971), and a Ph.D. in ecology and evolutionary biology from the University of California, Irvine (1977). He has taught courses in 'Fundamental Ecology' at UC Irvine, 'Man and the Environment' at the California State University at Los Angeles, 'Systems Ecology' in the College of Natural Resources at Colorado State University, and 'Image Processing Applied to Classroom Teaching' at Foothill College, Los Altos Hills, California. He has served as a consultant in Systems Ecology to the United Nations Educational, Scientific and Cultural Organization (UNESCO) in Nairobi, Kenya. He was a Research Associate in the Department of Agricultural Engineering, University of Idaho and a Systems Ecologist with the Agricultural Research Service, U.S.D.A. in Boise where he was the project modeler for the rangeland modeling project called SPUR - the Simulation of Production and Utilization of Rangelands. Currently he is studying terrestrial plant response to increased ultraviolet radiation in the polar regions of the earth and plant response to beamed microwave radiation. He also uses supercomputers to do ecosystem modeling. He has developed web-based 4-12 teacher guides and community college Earth Science curriculum materials. He also serves as webmaster for the Project ALERT (Augmented Learning Environment and Renewable Teaching) web pages, and is one the NASA leaders in Project ALERT.
