Research Statement
Plant/pathogen/pest relationships are complex and involve interactions among biological, chemical, and physical processes. The research and extension focus of our laboratory is on understanding and engineering elements of these processes to produce and support appropriate pest management and food sustainability strategies. Our work emphasizes development and implementation of alternatives to application of pesticides, primarily using quantitative and qualitative manipulation of passive solar energy, knowledge-based utilization of organic materials and by-products, and other applications of ecological and agricultural engineering.  Appropriate technology and circular economy issues are emphasized.
