Marcus Sheaves is a Professor in the College of Science and Engineering, where he is Head of Marine Biology and Aquaculture, Deputy Director of JCU’s Centre for Tropical Water & Aquatic Ecosystem Research (TropWATER). Marcus also leads JCU’s Estuary and Coastal Wetland Ecology Research Group, and leader of the Science for Integrated Coastal Ecosystem Management consortium..

 Marcus has researched ecosystem and fisheries ecology of tropical estuaries, coastal wetlands and mangrove systems since the early 1990s. His research has focussed particularly on nursery ground utilisation and values, and critical thinking in environmental decision-making. He has published widely with over 70 peer reviewed publications since 2007. Marcus leads a number of substantial research projects within Australia and across the Asia-Pacific region. He has extensive collaborations with research and management organisations both within Australia and internationally.
