I am a Professor in the Department of Natural Resources and the Environment at the University of New Hampshire. By training, a marine invertebrate zoologist, my research focuses on understanding the processes that are responsible for the biodiversity we observe in nature. To this end, I employ a variety of techniques including molecular approaches, as well as traditional light and electron microscopy, and immunocytochemistry; all in an effort to understand the phylogeography, population genetics, and ecology of animals.

Two specific projects in my lab focus on free-living, marine flatworms: one includes the systematics, phylogenetics, biogeography and development of polyclads (an ongoing collaboration with my former grad students, Drs. Marcela Bolanos and Sigmer Quiroga), the other focuses on the fine-scale population genetics of meiofaunal kalyptorhynch and proseriate turbellarians (a collaboration with Drs. Julian P. Smith III, Winthrop University, SC and Steve Fegley, Institute of Marine Sciences, University of North Carolina, Morehead City, NC).

Additionally, I have a long-standing collaboration with Dr. John Litvaitis, a wildlife ecologist also in the Department of Natural Resources. While John focuses on understanding the population dynamics of species in fragmented habitats, my contributions include determining how fragmentation and landscape features affect the genetics of populations.
