Francis Epplin, Ph.D.

Regents Professor
Agricultural Economics
Jean and Patsy Neustadt Chair



Epplin’s research focuses on the economics of agricultural production and resource use. He conducts economic analysis of alternative crop and livestock production systems including the expected economics of dedicated energy crops.

“Our comprehensive field-to-biofuels models are designed to identify key cost components and potential bottlenecks, and to reveal opportunities for reducing costs and prioritizing research. The models can be used to determine for a specific region the most economical sources of biomass, optimal number of harvest machines, timing of harvest and storage, biorefinery size, biorefinery location, and conversion system. They can also be used to determine the biofuel price required for an economically viable cellulosic biofuel system. The ultimate goal is to develop a profitable business model.”
