Brief description of job duties
My appointment at the University of Florida is a 70% research and 30% extension split, based at the Mid Florida Research and Education Center (MREC). My primary responsibility is to improve integrated pest management (IPM) for arthropod pests of ornamental plants, trees and shrubs. My research efforts are focused on both nursery and outdoor landscapes. The continued occurrence and rapid spread of invasive species of arthropod in Florida’s urban landscapes makes this need especially pressing. To that end I conduct basic and applied research with beneficial arthropods, including insectary-reared biological control agents, microbial and other biorationale pesticides, and conservation biological control methods. Regarding instruction, I oversee graduate students working on such topics. I serve as the primary supervisor, currently for one Masters and one PhD student, and also on various other student committees. My extension duties involve working with homeowners, professional landscapers, extension faculty and schools to deliver up to date information on new pests and as needed various methods for their management.
