Microalgal stress physiology and sulphur metabolism T
his research area involves understanding microalgal physiology and their responses to environmental perturbations. It also aims to understand the link between cell physiology and sulphur production with respect to oxidative stress and antioxidant function in photoautotrophs, including phytoplankton, corals and foraminifera.
Phytoplankton-bacteria interactions I
n collaboration with microbial ecologists, this work aims to determine how phytoplankton physiological condition influences bacterial associations at different spatial scales (micro - oceanographic). Specifically, it investigates how changes in the production and sensing of chemical cues (like DMSP) regulate marine microbial interactions.
Marine microalgal symbioses (host-symbiont interactions) U
tilising single cell methods such as epifluorescence confocal microscopy, microscope fluorometry and infra-red microspectroscopy, this work examines the physiological and biochemical responses that occur at the cellular scale in corals and foraminifera.
