A short introduction...
I am a senior lecturer at the University of Technology Sydney (UTS) where I head the Marine Microphycology Laboratory. My research couples cell physiology, photobiology and biochemistry to investigate microalgal traits and adaptation in a changing world. Of particular focus is the role of biogenic sulphur in microalgal stress physiology and its influence on marine social networks. My research spans a broad range of organisms (phytoplankton, corals, foraminifera) and habitats (coral reefs, temperate coastal waters, Antarctic waters, sea ice), covering a range of spatial scales from sub-cellular to ecosystems.

In the Marine Microphycology Lab our research is aimed at trying to answer how biogenic sulphur compounds influence microalgal physiology and lower trophic interactions in the marine environment. Currently, the lab consists of three PhD students, one Honours student and one postdoc.
