Marie Walsh holds a B.S. in Biology and Chemistry from Illinois College, and an M.S. and Ph.D. in Agricultural and Applied Economics from the University of Minnesota. Currently, she is an Adjunct Associate Professor in the Department of Agricultural Economics at the University of Tennessee, Head of M&E Biomass (a private consulting firm), and serving as a shared faculty with the U.S. Department of Agriculture Cooperative State Research, Education, and Extension Service.    Dr. Walsh was formerly a Research Staff Economist and Leader of the Integrated Systems Analysis Task in the U.S. Department of Energy Biomass Feedstock Development Program at Oak Ridge National Laboratory. Research led by Dr. Walsh was multi-disciplinary and integrated technical, energy, environmental, economic, and policy factors. Major projects include the development of a county level database of biomass feedstock supply (agricultural residues, energy crops, forest residues, mill residues, urban wood wastes); analysis of the potential for, and impacts of, producing energy crops; economic impacts of using corn stover to produce ethanol in the midwest; and economic impacts of using biomass for co-firing in the Southeast.   Research led by Dr. Walsh, among other uses, has been used to (1) establish a Biomass Pilot Program using Conservation Reserve Program acres, (2) incorporate into the 2003 Farm Bill the ability to produce and harvest energy crops on CRP acres, (3) establish the goal of tripling bioenergy and bioproduct use in Presidential Executive Order 13134, and (4) comprise the biomass feedstock supply curves used in the DOE Energy Information Agency NEMS model used for policy analysis and the Annual Energy Outlook.   Dr. Walsh was selected as an American Association for the Advancement of Science Congressional Science Fellow, and worked at the U.S. Congress' Office of Technology Assessment where she conducted analysis of policy issues related to agricultural biotechnology. She participated in several studies and was project director for the study Industrial Uses of Agricultural Commodities.   She has previously served as the U.S. Representative to the Integrated Bioenergy Systems Activity of the International Energy Agency's Biomass Utilization Task where she helped to develop the BEAM model to evaluate the costs of producing and collecting biomass feedstocks, transporting and storing the feedstocks, and converting them into bioenergy and bioproducts. Dr. Walsh worked as a research assistant at Washington University Medical School where her duties included cloning insulin and nerve growth factor genes. She also has served as a Peace Corps Volunteer teaching biology and physics in Ghana, West Africa.
