Our research goal is to understand the processes that control the flow of carbon and energy through the marine carbon cycle. Phytoplankton are the single celled microbes that use light energy to convert carbon dioxide to organic carbon in aquatic systems. Research in my lab focuses on understanding strategies used by phytoplankton to optimize their growth. We are interested in determining how these strategies vary with different environmental conditions (i.e., nutrients, light, CO2, pH) and between species. Understanding these growth strategies can then be used to improve global models of primary production and models of microbial phototrophic growth.
