Dr. Paul M. Severns is an Assistant Professor of Plant Disease Epidemiology at the Department of Plant Pathology, the University of Georgia. He received his PhD degree in Botany and Plant Pathology (Ecology and Evolution emphasis) from Oregon State University. He is interested in understanding the basic ecological and evolutionary underpinnings of plant disease epidemic spread (a form of biological invasion) and how these insights can be used to generate refined projections of disease dispersal and more efficient methods of outbreak control.
