I lead and manage long-term monitoring and applied research programs in tropical coral and seagrass ecosystems. I have over 18 years’ of experience using spatial analysis and mapping to monitor habitats at risk. My research interests span from seagrass habitats to coral reefs with a focus on the ecology and photobiology of marine plants, reef resilience strategies, science-driven management of ports and dredging impacts on habitats of the Great Barrier Reef, and building meaningful partnerships with traditional owners, community groups and the tourism sector.

I focus on forging partnerships across industries using alliances to springboard impactful and scalable strategies to research and inform management of reef and coastal assets. I lead science delivery and integration for the Great Reef Census, a citizens science approach that uses the diverse fleet of vessels spanning industries on the GBR to deliver scalable research and monitoring that feeds directly to reef management and conservation goals. I have helped foster a shared economy approach to science and partnerships out of Cairns with close collaborators Citizens of the GBR, Mars Sustainable Solutions, Dawul Wuru Indigenous Corporation, Experience Co and Reef Restoration Foundation. 

In recent years, my work has centred on the marine optical environment and how photosynthetic processes dictate the success of marine plants and how this impacts the habitat at a broader scale. Using fine-scale fluorometric technology together with field-based rapid-assessment techniques our research team has built a strong understanding of natural variability versus impacts from environmental threats.
