Research Interests & Areas

I am a multidisciplinary research entomologist and ecologist with a spectrum of interests across basic and applied science. Topics I work on include insect migration, insect biodiversity and conservation, biological control, toxicology, faunistics, science outreach, and integrated pest and pollinator management (IPPM). I am especially interested in the biology and ecology of hover flies (Diptera: Syrphidae) and other beneficial insects.
