Research Interests:

My research program includes an ongoing study of the systematics of subterranean amphipod crustaceans, primarily in the family Crangonyctidae but also in the families Bogidiellidae and Hadziidae. The research incorporates alpha taxonomy, phylogenetic analysis, and biogeographic interpretation. It has been funded by three grants from the National Science Foundation, including most recently a PEET (Partnerships for Enhancing Expertise in Taxonomy) grant from1995 to 2002. I also have a general interest in the evolutionary biology of subterranean groundwater crustaceans, especially with respect to their origin and geographic distribution. In addition, I have funding from the Cave Conservancy of the Virginias to upgrade and expand a species/locality database for the large, predominately North American, subterranean amphipod genus Stygobromus.In addition, I consult frequently with both public and private agencies on the conservation of cave and karst ecosystems and protection of rare and endangered species that inhabit these systems.
