معرفی
Walter Mahaffee holds a Courtesy Appointment in the Department of Botany and Plant Pathology at Oregon State University (OSU), affiliated with the USDA Agricultural Research Service (ARS). His research focuses on microbial ecology in plant systems, particularly the epidemiology and management of plant pathogens in horticultural crops. Key areas include fungicide resistance mitigation, airborne pathogen monitoring, and sustainable disease control strategies like UV-C light applications. Mahaffee’s work bridges field diagnostics, molecular tools, and computational modeling to improve agricultural disease management.
Education: Ph.D. in Plant Pathology from Auburn University (1996). Professional affiliations include the American Phytopathological Society and American Society for Microbiology Education.
Research projects include: (1) inoculum monitoring as a decision support tool, (2) fungicide resistance dynamics in Erysiphe necator (grape powdery mildew), and (3) development of cyber-physical systems for viticulture risk management. His lab employs innovative sampling techniques and genomic approaches to understand pathogen dispersal and host-pathogen interactions.
Recent publications emphasize airborne pathogen tracking, UV-C light efficacy, and socio-ecological strategies for collective pest management in vineyards. Awards include recognition for commercialization of agricultural technologies and contributions to hop industry sustainability.
Advising: Mentors graduate student Eliza Allen and oversees a team of postdoctoral researchers and technicians. Research infrastructure includes the USDA-ARS Horticulture Crops Research Lab in Corvallis, Oregon.
