Invasive Species: Pathways, dispersal, environmental costs/benefits. Specifically focused on interactions with climate change (particularly ocean acidification, storminess and eutrophication), aquaculture, hull fouling and the marine energy renewable industry.
Biofouling of artificial structures (including vessels, offshore renewable energy structures, marinas, ports and aquaculture installations)
Integrated Aquaculture: Use of nutrient extracting organisms to mitigate the impacts of aquaculture.
