My research addresses the cell biology of key marine organisms that are of critical importance in global carbon and nutrient cycling.  I also use algal cells as experimental models for understanding fundamental aspects of cell biology, including cellular transport, homeostasis and signalling.  I study environmentally important groups, such as the calcifying coccolithophores and silicifying diatoms, applying a multidisciplinary approach to understand the molecular mechanisms underlying major biogeochemical processes.  A key strategic driver of much of this research is to provide a better understanding of how phytoplankton populations may respond or adapt to changing conditions in the oceans.  Model algal systems such as Fucus and Chlamydomonas are also studied to understand the molecular mechanisms underlying intracellular signalling.  Along with comparative physiological and genomic studies this research is shedding new light on the evolution of signalling mechanisms in eukaryote organisms.
