My research is focused on the conservation, management and restoration of ecosystems. I am currently investigating new approaches to improve the outcomes of threatened species reintroductions, the utility of rewilding as an approach for ecosystem restoration, the role that top predators play in sustaining biodiversity and managing the impacts of introduced species including feral cats, foxes, feral goats and cane toads.
