Research Information

Research Interests

My interests are mainly in the areas of wildlife disease ecology and species conservation in aquatic systems. I also act as a researcher and consultant in freshwater mussel conservation efforts and stream management in western Pennsylvania and most of West Virginia. In my work in coastal estuarine systems, my students and I have teamed up with Dr. John Wnek (Project Terrapin) to study the demographics, movements and overall health of diamondback terrapin (Malaclemys terrapin) in highly developed portions of the Mid-Atlantic. We are also exploring the predator-prey dynamics of blue crabs (Callinectes sapidus) and their snail prey (Ilyanassa obsoleta). This snail is parasitized by several trematode species, including one that uses blue crabs as a second intermediate host. Our early findings suggest that infected snails spend more time foraging, and might risk predation by crabs while uninfected snails do not.
