Agriculture and the Environment: This is the constant theme of my work since my undergraduate days. Within the AFE program, this incudes assessments of resource use (land, water, etc.) by current and future production strategies and systems. My current efforts are informed by having conducted decades of field and laboratory research on crop management, alternative crop development, short- and long-term effects of cropping systems on potato yield and quality, management strategies to improve soil quality, manure nitrogen and phosphorus availability, soil carbon sequestration and cycling, emission of greenhouse gases from high-value production systems, and grain production for organic dairy systems.
Sustainable and Equitable Food Systems: Environmental outcomes are one of several realms or domains that are encompassed by a Sustainable Food System. The Friedman School is uniquely placed to link agriculture, nutrition and health, economics, and individual and societal well-being. Of particular interest is the role of diets as a driver of sustainability outcomes, and includes policy-oriented efforts such as my role advising the 2015 Dietary Guidelines Advisory Committee, to include sustainability in the Dietary Guidelines for Americans.
Interdisciplinary Education and Mentoring: The AFE program is inherently interdisciplinary, as is the Friedman School. My particular interest is to provide education and research opportunities so that students can develop the specific skills necessary to work at the interface of different disciplines or domains.
