My research program focuses on US and international dairy production, markets, and policy. Current areas of research include modeling the impacts of domestic US dairy policy alternatives, dairy trade policy and international trade patterns, the impacts of milk pricing regulations in US dairy markets, assessment of the dynamic impacts of dairy product promotion, and the economics of dairy production and marketing systems in developing countries. Major planned activities over the next few years include further refinement of a US dairy policy model using the system dynamics approach, refinement and extension of spatially-based analyses of the US dairy processing sector, further assessment of the determinants of financial performance of small-scale dairy processing enterprises in New York. I work as a part of a program that emphasizes applied research and extension. I engage in communication of research results in ways appropriate for target audiences in the dairy industry and government. I also contribute to teaching through lectures in courses in AEM, IARD and Animal Science. In addition to my in activities AEM, I have campus-wide responsibilities as coordinator of the Cornell System Dynamics Network (CSDNet). The objective of CSDNet is to promote awareness and research applications of systems thinking and dynamic modeling, particularly System Dynamics, throughout Cornell.
