My primary research interests focus on the population dynamics and feeding ecology of immature and adult mosquitoes. Current projects involve: 1) examining the trophic dynamics and food web relationships of mosquito larvae and other macroinvertebrates in relation to the maintenance and possible transmission of Mycobacterium ulcerans, the causative agent to Buruli Ulcer, a necrotic skin disease that infects people living around the equatorial regions of the world, specifically West Africa, Australia and South America; 2) black fly surveillance in the Raritan River, NJ; 3) Larval mosquito population response to Hurricane Sandy, 4) Microbial community responses to biocidal treatments of larval black fly and mosquito habitats, 5) larval and adult macro invertebrate community response to stream restoration. Other research areas being driven by students in my lab include projects focused on: (1) crayfish life history responses to invasive plant diets, (2) adult mosquito response to Ailanthus altissima extract as a repellent or adulticide, 3) development of a reference larval mosquito identification manual for Hunterdon County, NJ.
