I study the microbial ecology of marine planktonic ecosystems using advanced technology for the automated measurement
of these microbial populations and their activity at the single cell level. I have developed methods for accurate detection, counting,
and cell measurement for bacteria and protists in natural aquatic ecosystems using image analysis techniques. This technology is used
to study the community size and trophic structure in a variety of marine systems, including the North Atlantic spring bloom, the
equatorial Pacific, the Sargasso Sea, the Gulf of Maine, and Georges Bank.

the oceanic "biological pump".
