Professor Peter Mumby began his career helping to design marine reserves in Belize and experienced first-hand the limited scientific basis for decision-making. He began a research pathway to provide science that can inform practical conservation and management action. His research combines field observations, experiments, remote sensing, and ecological modelling to answer questions about ecosystem resilience, impacts of climate change, marine reserve functioning and design, connectivity of ecosystems, coral reef fisheries, and marine spatial planning to capture ecosystem services. Peter collaborates extensively with other fields including economics, engineering, oceanography, and business. He gained a PhD at the University of Sheffield, followed by a NERC Post-doctoral fellowship at the University of Newcastle, a Royal Society fellowship at the University of Exeter, and moved to Brisbane to take up a prestigious ARC Laureate Fellowship in 2010. He is a professor at The University of Queensland, a Pew Fellow in Marine Conservation and winner of the Rosenstiel Award for Contributions to Marine Biology, Marsh Award for Marine Conservation, and the inaugural ISRS Mid-Career Award for contributions to reef science.
