Dr Susan Kimmance is a microbial ecologist at PML, whose main area of research is the functional ecology of phytoplankton and viruses. She is particularly interested in the impact of abiotic and biotic stress on phytoplankton physiology and mortality and how this influences primary production, microbial food web dynamics and biogeochemical cycling.

After completing a degree (BSc Marine Biology Hons.) and PhD (‘The interactive effects of temperature and food availability on growth responses of aquatic protists’) at the University of Liverpool, I joined PML in 2003. My research has since combined laboratory experimentation with coastal and oceanic fieldwork to investigate primarily the functional relationships between algal viruses and their phytoplankton hosts, aiming to elucidate the ecological importance of viral control of primary production in comparison with other mortality pathways such as microzooplankton grazing or cell death. Linking phytoplankton to stress-induced production of marine trace gases has been an additional focus of my research (in collaboration with the trace gas group at PML): assessing the potential antioxidant role of DMSP; the fate of DMSP production through grazing and viral lysis; and determining how the physiological processes leading to DMS production are affected by changing environmental conditions.
