Research Projects

As a microbial oceanographer my research interest is in the study of the interaction of phytoplankton organisms with their geochemical environment. I investigate the factors determining their growth and the strategies allowing them to adapt to different environmental conditions. My current perspective involves the use of both physiological and molecular techniques for the analysis of phytoplankton gene expression patterns to investigate phytoplankton nutrient physiology in model cultures and field communities.
