About Marie

I am a biologist with a strong applied research focus and experience in the fields of applied algal biology and cultivation, biochemistry, and product development for food, feed, and human and animal health applications. As Program Leader for the Entrepreneurial Universities Macroalgal Biotechnology Programme, I lead a team focussing on the development of a sustainable seaweed aquaculture industry in NZ, the cultivation of freshwater and marine macroalgae for bioremediation of nutrient rich waste waters, and the development of novel bioproducts from the resulting biomass. Specific research interests are algal product development for food, feed, and human and animal health applications in circular bioeconomy models, and the use of seaweed for enteric methane mitigation in ruminants.
