We study the coastal marine ecology of dynamic tidal wetlands, and their response to global change – that is, contemporary and historical changes in climate, sea level, invasive species, and nutrient availability. We are particularly interested in understanding abiotic effects on and species interactions between strong interactors such as foundation species and ecosystem engineers in driving patterns at the landscape scale. We work closely with environmental agencies and land managers, as our findings often inform the conservation and restoration of valuable coastal ecosystems.
Our home base is in downtown Washington, DC at the George Washington University. During the growing season, we spend most weeks afield surveying natural patterns, asking new questions, and setting up ecological field experiments in the tidal wetlands of the Chesapeake Bay and Mid-Atlantic coastal bays. Please read about some of our current research and activities on these pages.
