Curriculum Vitae

Population and community ecology of marine plants, algae and invertebrates

My research program uses both descriptive ecology and manipulative experiments to understand the organization and dynamics of coastal plant, algal and animal communities. Specifically, my work on New England shores has focuses on (1) how abiotic and biotic factors influence zonation in coastal salt marshes and (2) how direct and indirect interactions between crab predators and consumers can influence the abundance of foundation species (barnacles and fucoid algae) on New England rocky shores.
