Biography
I am a seagrass and coastal ecosystems ecologist. My research facilitates the protection, conservation, biological diversity, rehabilitation, management and sustainable development of seagrass resources. I am particularly interested in the status and condition of seagrass resources across a range of scales (from local to global), understanding the role of disturbance, determining thresholds of concern and investigating resilience of seagrass ecosystems. I am also interested in the relationship between seagrass and associated fauna, the impacts of declining water quality and climate change.
