Long CV

Professor Tyner's research interests are in the area of energy, agricultural, and natural resource policy analysis and structural and sectoral adjustment in developing economies. His work in energy economics has encompassed oil, natural gas, coal, oil shale, biomass, ethanol from agricultural sources, and solar energy. Much of his recent work has focused on economic and policy analysis for biofuels.

His recent international work has focused on agricultural trade and policy issues in developing economies, particularly in the Middle East, North Africa, and West Africa. Professor Tyner has extensive overseas experience in Asia, Africa, the Middle East, and Central and Eastern Europe including short term assignments in seventeen countries. He also has long term overseas experience in India and Morocco. He is fluent in French.

Dr. Tyner and his students have received numerous awards from Purdue and the AAEA. In 2005 he received the AAEA Distinguished Policy Contribution Award. In 2007 he received the “Energy Patriot Award” from Senator Richard Lugar. In 2009, he was named the Outstanding Graduate Educator in the College of Agriculture, received the College Team award (with colleagues) for biofuels research, and received (with Abbott and Hurt) the AAEA Quality of Communication award. He teaches a graduate course in benefit-cost analysis.

Professor Tyner is author or co-author of three books: Energy Resources and Economic Development in India; Western Coal: Promise or Problem (with R. J. Kalter); and A Perspective on U.S. Farm Problems and Agricultural Policy (with Lance McKinzie and Tim Baker).
