Research Interests:

I am interested in community ecology, population ecology, and the effects of environmental factors on aquatic invertebrates and fish. Much of my early work focused on the natural diet of oyster larvae and their position in the food web of Chesapeake Bay. More recently, I have examined the biology and ecological impacts of invasive species such as zebra mussels and round gobies, both of which have devastated many North American lakes and rivers. I also work on the restoration and conservation of coral reef organisms such as sea urchins, queen conch, spiny lobster, and the Nassau grouper. Newer, additional projects include (a) the effects of winter road salt and sand on the survival of young trout and salmon and (b) factors that influence the dispersal and lifespan of oyster larvae along the east coast of North America. I collaborate with undergraduates on all recent projects and include them in co-authored papers and conference presentations. If you are interested in aquatic biology, please discuss possible summer or academic year projects with me.
