Research Leader
Research Leader
Cell: 509-439-5170
Education:
BS Biology/Environmental Science, Sheperd College, Shepherdstown, WV, 2000
MS Entomology, University of Arkansas, Fayetteville, AR, 2004
PhD Entomology, University of Kentucky, Lexington, KY, 2007
Research Interests:
Rodney conducts research on biology and management of insect pests of tree fruits and potatoes, with an emphasis on non-crop sources of insect vectors of crop pathogens. He uses molecular gut content analysis to identify the dietary history of Hemipteran vectors (leafhoppers and psyllids) and uses that information to infer the landscape level movements of the vectors prior to their capture.
Laboratory Personnel:
Heather Headrick, Biological Science Technician (Molecular Laboratory/gut content analysis)
Pauline Anderson, Biological Science Technician (Greenhouse/Insect rearing)
Rachel Cook, Biological Science Technician
Bonnie Ohler, Research Associate (WSU)
Adrian Marshall, Entomologist (Post-doc)
