I have been a Research Plant Pathologist with the Agricultural Research Service, USDA, and a Professor of Plant Pathology, Cornell University since 1987. The main areas of research in my lab are the mechanisms of insect transmission of plant viruses and the epidemiology and management of plant viruses affecting potato and cereal crops. Additional details on my research program are available at USDA-ARS and Cornell University (web page link at left).
As the Principal Investigator on the PVY Management project I serve as the project coordinator. My research seeks to shed light on the multiplicity of PVY strains in potato and the symptoms each causes in plants and tubers. Most important—what contributes to potato tuber necrotic ringspot disease and how can this be prevented or avoided? We will examine resistance in potato breeding lines to the PVY strains, determine the efficiency of aphid transmission of strains and strain mixtures, explore aphid seasonal life history and chemical control, and improve in-season and post harvest detection of PVY strains. Our goal is to build optimal disease detection and management programs.
