Research Interests: My primary research interests over the past 21 years involve the role of biological community structure in the cycling and export of organic matter from the surface ocean. In recent years, this has grown to include the study of some unique biological processes, their disproportionate influence on nutrient and carbon cycles and their relative importance on global scales. As my career has evolved to include running the Wrigley Institute for Environmental Studies, I have been able to keep an active research program in this area. However, I have also started to add other research foci that reflect a broader set of marine and environmental interests. Key publications: Karl, D. M., N. R. Bates, S. Emerson, P. J. Harrison, C.
