I am a bio-optical oceanographer specializing in the development of remote and in situ optical methods to determine phytoplankton concentration, composition, and productivity in both marine and freshwater systems. My research programs emphasize the relationship between the physiology and optical characteristics of phytoplankton on scales of individual cells in the laboratory, to discrete populations in the water column, to communities that can be sensed by ocean color satellites.
