Bio & Research Interests

I am interested in the ecology, biology and taxonomy of crustose coralline algae (CCA), as well as the effects of ocean acidification and global warming on this important group of algae. During my PhD, I looked at the effects of ocean acidification on the supply-side ecology of CCA. Being an important component for the reef and one of the most sensitive groups to ocean acidification, it is essential to explore the potential impacts on the supply-side ecology, as this will provide a better understanding of the implications to adult population and subsequent effects on other reef organisms such as corals.
