Research and Cooperative Extension Experience:

Twenty years research experience with plant diseases including work published on viruses, bacteria, fungi and nematodes. Research projects were conducted in the field, laboratory and greenhouse. Current research program development emphasizes epidemiology and control of fungal, bacterial and nematode diseases of potatoes, dry beans, and sugar beet. Extension work includes responsibility for Wyoming plant pathology programs, service provided by the University of Wyoming Extension Plant Pathology laboratory as well as plant pathology training and support for Wyoming Crop Improvement Association seed certification programs. Statewide, regional, national, and international educational and service programs pertaining to plant disease detection, diagnosis and control are being developed for extension and research audiences, large agricultural producers and homeowners.
