The MACRO research group (the Centre for Macroalgal Resources and Biotechnology) provides research, development and implementation for cost-effective delivery of algal biomass to value-add to the treatment of discharge water for aquaculture, municipal waste water treatment,agriculture, mining, mineral processing and energy generation.

The research group focuses on innovative applied research that can move quickly to commercial demonstration with industry  partner MBD Industries.  MBD uses the outcomes of this research to create innovative processes for bioremediation and subsequent end-use of the algal biomass ranging from food products to fertilisers and biostimulants.to.

As the leader of MACRO, Rocky’s role focuses on the planning, organisational and management requirements for the successful delivery of multi-disciplinary research and its application.
