- Research Disciplines
The Macroalgal Biofuels and Bioproducts research group provides research, development and implementation for cost-effective delivery of algal biomass to value-add to mining, mineral processing, power generation, aquaculture and agriculture.
The research group focuses on innovative applied research that can move quickly to commercial demonstration. Industry partner MBD Energy uses the outcomes of this research to create innovative products and processes ranging from food products to biofuels, and biological carbon capture and storage using biochar.
As the leader of the Macroalgal Biofuels and Bioproducts project, Rocky’s role focuses on the planning, organisational and management requirements for the successful delivery of multi-disciplinary research and its application.

- Current Funding
Current and recent Research Funding to JCU is shown by funding source and project.
QLD Department of Science, Information, Technology and Innovation - Advance Queensland Innovation Partnerships
Health products from Queensland algae
- Indicative Funding
- $53,559 over 2 years (administered by University of Southern Queensland)
- The overarching aim of the project is to generate the evidence required to create new health products from algae produced in Queensland by the industry partner MBD. The project team has recently demonstrated the potential therapeutic benefits of using algae in diets to deliver nutrients and minerals. This work shows that algae are functional foods, that is, foods that could reverse or prevent disease and deliver health benefits. We will now test whether a range of products can be developed from different algae to decrease or prevent obesity, improve muscle tone especially in the elderly, and prebiotics for gut health.
