Brief Description of Research: My research interests include biogeochemical studies focusing on community composition and productivity of phytoplankton, and associated carbon fluxes in oceans. For this purpose, I have combined several approaches based on remote and in-situ measurements and laboratory experiments. These include primarily HPLC (High performance liquid chromatography) biomarker pigments, remote sensing of ocean color, and seawater carbon chemistry.
