Research Fellow – School of Earth and Environment & ARC CoE Coral Reef Studies, University of Western Australia (2015 – )

Research Fellow – Institute for Marine and Antarctic Studies, University of Tasmania (2013 – 2015)

I am originally from New Zealand, where I completed a MSc at Victoria University of Wellington in 2007. I worked as a research assistant in 2008 at the Department of Botany at Otago University and commenced a PhD there in 2010. His dissertation examined the capacity of macroalgal metabolism to reduce the effects of ocean acidification on calcifying species under a variety of environmental conditions. In 2013, I took up a Research Fellow positon at IMAS in Tasmania, examining macroalgal inorganic carbon use and pH variability in rocky reefs around Tasmania. My current research at UWA examines how organism physiology and the environment will interact to influence the response of coralline algae to ocean acidification and warming. I am also interested in the roles of environmental variability, hydrodynamics, and light on autotrophic physiology and ecosystem functioning.

Research Interests

I am interested in estimating how organism physiology and environmental variability will interact to influence the response of coralline algae to ocean acidification and warming.  I am also interested in the roles of pH variability, hydrodynamics, and light on inorganic carbon acquisition and am interested in predicting the effects of ocean acidification on ecosystem functioning.

I am actively looking for potential PhD students.  Please feel free to email me if any of your research interests align with mine.
