My research and extension programs aim to help growers of the San Luis Valley to make educated decisions on the management of plant diseases of major crops, in particular potato. To achieve the objectives of my research program, I conduct laboratory and field research to address issues facing growers and translate the outcomes to cultural practices and management approaches that can be adapted by the growers of the San Luis Valley. My research interests include the characterization of plant pathogens, diagnosis, epidemiology, and management of plant diseases. My extension program focuses on the identification of research priorities, and the dissemination of the knowledge generated to the growers in a diverse, grower-friendly approaches.
