Senior Research Fellow
Qualifications: BSc Hons (Otago), PhD (James Cook University)
I am a marine ecologist with broad interests in applied environmental science. I completed my undergrad and BSc Honours in Zoology and Ecology at the University of Otago. Following several years working at the then New Zealand Ministry of Fisheries, I moved to Townsville and completed my PhD in coral reef fish ecology at James Cook University. A desire to work in a more applied field led to a postdoc at James Cook University in Macroalgal Biofuels and Bioproducts. This research aimed to identify environmental tolerances and optimise biomass productivities of species of macroalgae for the production of macroalgal bioproducts. Following a brief period working at the Bay of Plenty Regional Council as a Coastal Scientist, I have returned back to an academic career as part of the Entrepreneurial Universities Macroalgal Biotechnology Programme.
My research is centered on the growth and production of macroalgae (both freshwater and marine/seaweeds) and has two key focal areas. First, is the use of live macroalgae to bioremediate nutrient rich wastewaters from a range of sources including agriculture, aquaculture, horticulture, and municipal waste treatment. Second, is the aquaculture of seaweeds to produce biomass for macroalgal bioactives and bioproducts. I am interested in understanding the ecology of target species and how this can be applied to optomise productivity and biomass characteristics under different environmental conditions. Underpinning both streams of research is the development of innovative technologies and processes to enable commercial scale cultivation. A central theme of my research is the development of a circular economy. Macroalgae can provide the foundation of a circular economy model that can be applied to agricultural, municipal and industrial systems to bioremediate wastewaters and generate new products.
