I am interested in community ecology, population ecology, and the effects of environmental contaminants 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) on the Great Lakes, the St. Lawrence River, and area lakes. I have also been working with students on the levels of toxic mercury in fish from fresh and marine ecosystems as well as its possible impacts on their reproduction. Students and I have also worked on the restoration and conservation of coral reef organisms such as sea urchins, queen conch, spiny lobster, and the Nassau grouper.
I teach courses such as Intro Bio, Marine Ecology, Animal Biodiversity, Ecology of Lakes & Rivers, and Food from the Sea. At times I also teach the biology course in our Adirondack Semester program called Ecology & Natural History of the Adirondacks.
