About Rebecca
I am a marine ecologist with broad interests in applied environmental science. 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 optimise 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.
