Zackary Johnson
Arthur P. Kaupe Assistant Professor of Molecular Biology in Marine Science

Our group broadly studies the abundance, diversity and activity of marine microbes. We are biological oceanographers , marine molecular ecologists , marine microbiologists and biogeochemists. Our research focuses on the marine cyanobacteria Prochlorococcus , the most abundant phytoplankton in the open oceans and an excellent model marine microbe, as well as the biotechnological applications of marine microalgae. We are at the Marine Laboratory as part of the Nicholas School of the Environment at Duke University .
