Professor Tyner's recent research interests are in the area of climate, energy, agricultural, and natural resource policy analysis. His work in energy economics has encompassed oil, natural gas, coal, oil shale, biomass, biofuels from agricultural sources, and solar and wind energy. Much of his recent work has focused on economic and policy analysis for biofuels and the interplay between biofuels policies and other energy policies. He has over 300 professional papers including three books and 110+ journal papers, published abstracts, and book chapters. His work has been cited over 4,900 times according to Google Scholar with an h index of 31 and i10 index of 87. His past work in energy economics has encompassed oil, natural gas, coal, oil shale, biomass, ethanol from agricultural sources, and solar energy. His current research focuses on renewable energy policy issues and the links among energy, agriculture, and climate change. He was Co-chair of the National Academy of Science Committee on the Economic and Environmental Impacts of Biofuels (2011). In 2016, he chaired a National Academy panel on advanced biofuels. He teaches a graduate course in benefit-cost analysis, which incorporates risk into the economic and financial analysis of investment projects.
Dr. Tyner and his students have received numerous awards from Purdue, the Agricultural and Applied Economics Association (AAEA), and others. 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. In 2013, he received the AAEA Distinguished Graduate Teaching award. In addition, in 2015, he received the Purdue Morrill award for career accomplishments that have had impact on society and the Honorary Life Member award (their highest honor and equivalent to fellow) from the International Association of Agricultural Economists. In 2017 Tyner was named a Fellow of the American Association for the Advancement of Science (AAAS).
