Research Interests

My research interests are in zooplankton ecology and physiology, coastal and deep-sea food webs, nutrient cycling, and marine detritus ("marine snow"). Much of my current focus is how zooplankton community structure affects flux of organic material and cycling of nutrients in the sea. Our laboratory has recently 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 on zooplankton community structure. We are also using long-term data sets to study the effects of climate change on zooplankton communities, and how these community changes may affect ocean biogeochemistry. I have worked in a number of marine environments including coastal California, the Antarctic, Bermuda and the Sargasso Sea, the subtropical and subarctic North Pacific, and the Chesapeake Bay.
