Ecology, wildlife management, conservation biology

My research is focused on the conservation and management of ecosystems. I am particularly interested in improving understanding of landscape and continental-scale processes that influence the structure of terrestrial and aquatic ecosystems and threaten biodiversity. I am currently investigating the role that top predators play in sustaining biodiversity, the ecology and biology of crocodiles and landscape scale approaches to control the impacts of invasive species, particularly, cane toads and foxes.
