  • Director / Department of Plant Pathology
Dr. Erin Silva is an Associate Professor and State Extension Specialist in Organic and Sustainable Cropping Systems in the Department of Plant Pathology as well as the Director for the Center for Integrated Agricultural Systems in the College of Agricultural and Life Sciences at UW-Madison. After completion of a PhD in Horticulture at Washington State University, Dr. Silva obtained a faculty position at New Mexico State University. During her tenure at NMSU, Dr. Silva taught courses on organic vegetable production, an experiential learning course integrating the working student organic Community Supported Agriculture (CSA) farm on campus. Dr. Silva initiated several organic research projects at NMSU, including work on cover crop-based reduced tillage for organic vegetable crops and breeding vegetables for organic production systems. These research themes continued as Dr. Silva moved into the first organic-focused research position at the UW-Madison College of Agricultural and Life Sciences in 2006. Through her work at UW-Madison, she has developed an internationally recognized program that improves the management of organic production systems and increases the profitability and sustainability for organic producers and rural communities. Her research program provides regional, national, and international leadership on the biological aspects of organic agricultural management, employing an agroecological approach that considers socio-economic factors impacting production decisions. She applies the knowledge generated through her research towards the development of innovative organic production strategies that benefit the farmer, the environment, and the consumer. Her research influences the strong organic sector that contributes to Wisconsin's agricultural economy, with Wisconsin second only to California as the state with the greatest number of organic farms. In continued support of these farms and the organic sector within the state, nation, and globally, her research and scholarly contributions continue to be directed in the broad area of the biology and agroecology of organic crop management, with emphases on cover crops, soil health, and genotype/ environment interactions.
