My research interests are about using mathematical models to help improve management. The focus of my work has been about the application of optimal control theory to invasive species management and in developing ecosystem models to predict how management actions will affect different species in an ecosystem.
I am also working on developing management strategies for treatment-resistant disease, modelling the effect of management on coral reefs, and on developing plant spread models for revegetation projects. Over the next three years I will be working on developing mathematical models of environmental systems and using them to inform management. These will include case studies at Booderee National Park, Macquarie Island, Lord Howe Island, Santa Rosa Island and Santa Cruz Island.
