Professor of Marine Science

My major research interests include marine phytoplankton ecology, physiology, bio-optics, biochemistry, primary production and taxonomy with particular emphasis on the effects of environmental factors on carbon and nitrogen metabolism, cellular composition and growth at the species and population levels of both laboratory cultures and natural populations.

Additional areas of interest include the biogeochemical cycling of organic materials in the upper layers of the ocean, in both coastal and oceanic environments and the effects of various dissolved and/or suspended components on the light absorption characteristics of marine phytoplankton.

Another area of research interest is the mass culture of marine and freshwater microalgae for the production of various commercially important materials including plant pigments and compounds with anti-cancer activity.

A new area of interest for me is that of Marine Science and Public Policy. This effort includes examination of coastal resources, scientific information and public needs as they each contribute to coastal resource management. In this regard, I work with the NOAA Coastal Services Center (www.csc.noaa.gov) to administer the NOAA Coastal Management Fellowship Program.
