Research Interests

Dr. Redinbaugh is a Research Leader and Research Molecular Biologist (Plants) in the USDA/ARS Corn, Soybean and Wheat Quality Research Unit in Wooster. Her primary research interest is identify and elucidate the molecular mechanisms underlying the genetic and biological bases of virus resistance and tolerance in maize. Current approaches include projects to: 1) identify and characterize emerging and re-emerging insect transmitted diseases of maize; 2) characterize resistance to multiple viruses in maize inbred lines; 3) develop genetic and genomic information on insect vectors of maize and soybean viruses; and, 4)understand virus factors required for disease, transmission, and interactions with crops, and to develop new virus-based research tools for studying genefunction in cereals.
