My 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 coral reef ecology in the Florida Keys and the natural diet of oyster larvae and their position in the food web of Chesapeake Bay. Since then, I have examined the biology and ecological impacts of invasive species such as zebra mussels and round gobies, both of which have devastated the Great Lakes and the St. Lawrence River. My research is now expanding to include the role of these exotics in the biomagnification of toxic mercury in local game fish and waterfowl. Finally, I also work on the restoration and conservation of coral reef organisms in the Bahamas, such as sea urchins, queen conch, spiny lobster, and the Nassau grouper.

Sample student projects I have supervised: 

Are Tug Hill Streams Mercury Hotspots?

A mangrove lagoon-seagrass complex on San Salvador, Bahamas.

Mercury Transfer to common terns and double-crested cormorants.
