I am a coastal ecologist with particular interest in seagrass biology. I aim to understand environmental requirements for maintaining healthy seagrass meadows. These are the foundation of healthy ecological communities, including dugong and turtle populations. I am interested in knowing what can impact upon seagrass meadow health and how we can most reliably detect these impacts. To this end, I am engaged in long-term monitoring and do the underpinning experimental research. I have extensive experience in localized impacts such as water quality and low light. However, I am increasingly exploring global-scale impacts and how these interact with local-scale stressors.
