Research Interests

My research interests are in zooplankton ecology and physiology, coastal and deep-sea food webs, and carbon and nutrient cycling. Much of my research program focuses on how zooplankton influence cycling of nutrients and organic matter, and how climate affects long-term change in zooplankton communities. Our laboratory has been involved in a number of projects with this theme, including the role of zooplankton vertical migration in transport of nutrients, the ecology of gelatinous zooplankton "blooms" and their affect on fluxes of organic matter, the importance of zooplankton in the cycling of dissolved organic matter, mesopelagic zooplankton and particle flux, and the effects of mesoscale eddies and a large river plume on zooplankton community structure. We are also using long-term data sets from the Western Antarctic Peninsula and the Sargasso Sea off Bermuda to study the effects of climate change on zooplankton communities, and how these community changes may affect ocean food webs and biogeochemistry.  I have worked in a number of marine environments including coastal California, the Antarctic, the Sargasso Sea, the subtropical and subarctic North Pacific, the Amazon River plume, and the Chesapeake Bay.
