My research interests center on the inter-relationships of ectoparasites and mammalian hosts. Most of my work has been with a highly specialized group of Diptera (true flies) called bat flies. Bat flies are obligate, blood-feeding parasites of bats worldwide, and are found nowhere else. These flies have evolved numerous morphological, physiological, and behavioral adaptations to their parasitic life on the bat’s bodies. These adaptations include a reduction of eye complexity and structure, a reduction of wing structure and functionality, the development of specialized setae and ctenidea (combs) to help keep them on the host, and a specialized reproductive strategy where females nourish the larval stages internally and give single births to "prepupae." Because of their intimate relationships with bats, bat flies provide a model system for studies in evolution and ecology. Recently, I have also begun research at WKU’s Green River Preserve, in order to understand relationships between wild rodents, ectoparasites, and Borellia burgdorferi, a symbiotic bacteria that sometimes causes Lyme Disease in humans.
