Research Interests

My research focuses on the ecology of estuarine environments of the Chesapeake Bay. In particular, I am interested in submerged aquatic vegetation (SAV) communities.  My current projects include monitoring of eelgrass abundance in the York River, and relating monthly and yearly changes to changes in water quality, particularly light availability and water temperature.  We have tracked two consecutive large-scale declines in eelgrass abundance in the lower Chesapeake Bay in 2010 and 2011 that are related in part to increased summer water temperatures, and are now monitoring the recovery from these events. I have also been  involved in a study comparing the water quality conditions in expanding eelgrass beds in the Virginia coastal bays with those at declining or static beds in the lower Chesapeake Bay.  In addition, I manage ongoing greenhouse experiments that evaluate the effectiveness of different aquaculture systems in growing both eelgrass and a low-salinity SAV, wild celery, from seed.
