Current research projects include characterising microbes, such as bacteria, in temperate and tropical reef organisms including fish guts, turf algae and corals to identify changes that are likely to occur under a changing climate. Steph's background in physiology and biochemistry involved looking at a sulphur compound naturally produced by corals, to understand how they can use this to protect themselves against coral bleaching under stressors including thermal stress and hyposaline conditions.
