I’m interested in basic questions about the ecology and evolution of marine organisms, especially the forces that control the origin and maintenance of diversity. My research involves correlative, experimental and theoretical approaches and studies at the genetic, population and community levels of organization. We conduct research in a wide variety of marine ecosystems from the intertidal zone to the deep sea. I received my BS in biology from UMass Boston and my PhD in Biology from Harvard University. I am currently a Professor in the Biology Dept. at UMass Boston, and in the Intercampus School of Marine Science.
