Dr. Terrance Hurley graduated with a Ph.D. in economics from Iowa State University in 1995. He is currently an associate professor in the Department of Applied Economics at the University of Minnesota where his primary research interests is the profitability, risk, and regulation of genetically engineered crops. He was one of the first agricultural economists to quantify the tradeoffs between the risk of insect resistance to Bt toxin and the long-term productivity of Bt corn, which resulted in the 2001 Outstanding Journal of Agricultural and Resource Economics Article award. He has worked closely with the EPA on insect resistance management requirements for Bt crops including service on two FIFRA Scientific Advisory Panels. More recently, he is among the first agricultural economists to quantify the effect of glyphosate weed resistance on the benefits of the Roundup Ready weed management program to farmers and the potential for using herbicide rebates to increase the use of residual herbicides for controlling glyphosate resistant weeds in the Roundup Ready weed management program. He currently serves as an associate editor for the American Journal of Agricultural Economics, Agronomy Journal, and Environmental Biosafety Research and recently served as an associate editor for the Journal of Agricultural and Resource Economics.


Dr. Raymond Jussaume is Professor and Chair of the Department of Sociology at Michigan StateUniversity. His academic degrees are from Southeastern Massachusetts University (B.A. Poli. Sci. 1976), the University of Georgia (M.A. Poli. Sci. 1981), and Cornell University (Development Sociology 1987), and he served as a Peace Corps volunteer in the Republic of Niger from 1978 to 1980. Most of his scholarship falls within the general theme of Development Sociology, with a particular emphasis on sustainable development. Dr. Jussaume also has academic interests in the Sociology of Community and of Agriculture. He has conducted field research in China, Japan, and France and has extensive experience working on interdisciplinary teams. Some of his more recent work has focused on how the evolution of the interactions between local and global agri-food systems may be impacting sustainable local development. He has published one book, nearly 50 peer-reviewed journal articles and academic book chapters, and numerous bulletins and popular manuscripts that have disseminated the results of his research to citizens.
