My research interests focus on the use of modern molecular tools to understand microbial processes in the oceans. This theme underlies my two major research programs-the molecular regulation of carbon fixation in phytoplankton and role of viruses in the ecology of picoplankton. Our research on carbon fixation studies the regulation of the major carboxylating enzyme, ribulose-1,5-bisphosphate carboxylase/oxygenase, RuBisCO. We have developed methods to detect transcript abundance for the gene for the large subunit of this enzyme, rbcL. Current research focuses on the regulation of this gene and genes for nitrogen assimilation in the coastal plumes that extend into oligotrophic oceans. We are also investigating the use of rbcL gene probes to detect harmful algal blooms. Our viral research is centered on the process of lysogeny, whereby viruses set up stable symbiosis with their hosts. We have recently described the seasonal abundance of lysogens amongst Synechococcus in Tampa Bay. Finally, we have developed molecular methods for the detection of pathogens such as enteroviruses in the marine environment.
