RESEARCH INTERESTS

My research interest is to apply my background in molecular and cellular biology to marine ecosystems and biota. For my Honours degree, I was working on the molecular and cellular effects of climate change on rocky shore gastropod species by looking at the total antioxidant capacity, lipid peroxidation and lysosomal destabilization rates of gastropod egg masses during temperature and salinity stress. I am now working on the production of atmospheric dimethylsulphide (DMS) and sulphur precursors (DMSP, DMSO) by reef building corals and its implications for climate regulation and oxidative stress. The first aim of my project is to identify the parameters that drive the DMS production over the reef and to determine the role that reef building corals play in climate regulation through the production of DMS and precursors. Another aspect of my study is to focus on the use of DMS, DMSP and DMSO as antioxidants by the coral-zooxanthellae symbiosis under various stressors, as a means of adaptation.
