My vision is aimed at understanding the overall regulations of metabolic and signaling pathways in algae in conjunction with the evolutionary proceedings of the incorporation of plastids, originating from a photosynthetic prokaryote, into the overall architecture of the eukaryote cell. I believe that by following my current research plan, new findings related to the structure and function of photosynthetic membranes and cell signaling in phytoplankton will lead to the discovery of yet unknown aspects of the “tree of life” and deepen the understanding of the relationship between phytoplankton physiology and the biogeochemistry of Earth.
