General Research:
Primary interests are the intersection of agriculture and the environment, and the development and implementation of sustainable production systems.

Current Research:
Current research interests include environmental impacts of agriculture (nutrient flows, carbon retention and loss, and climate change), and impacts of policy on adoption of agricultural practices and systems.

Past Research:
Past research responsibilities have included field and lab components addressing: 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.

Professional Affiliations
Education and outreach experience has included development of state- and regional-level educational programs in sustainable agriculture and nutrient management. As part of this effort, have given more than 500 presentations to growers, and more than 75 to scientists and farm advisors. Publications include more than 40 peer-reviewed journal articles, and numerous book chapters and trade and educational publications.
