Research Interests
My goal is to describe and protect the biological diversity and beneficial ecosystem functions of coastal marine habitats. Coastal oceans are threatened both by decreasing water quality and by overharvest of ecologically important marine species, so my research attempts to address the interaction of these “bottom-up” and “top-down” influences. I recently completed my doctorate at the Virginia Institute of Marine Science, where I studied the role of small, invertebrate grazers in mediating water quality and food-web changes in Chesapeake Bay eelgrass beds. I am now working as a postdoctoral fellow with the Smithsonian Marine Science Network, comparing the food-web structure and grazing impacts on seagrass in no-take marine reserves versus areas subject to fishing.
