Research Interests


I am a Wildlife Ecologist with broad research interests in ecology and wildlife management. I completed my BSc (Hons) (2001) and PhD (2005) at the University of Sydney, where I studied the ecology and management of mammalian carnivores. Much of my research has focused on the ecological interactions between native and invasive plants and animals. My current teaching and research focuses on restoring highly invaded ecosystems. This includes managing multiple invaders on islands, monitoring cryptic species, and applying landscape ecology principles to manage invasive species on continents. I have performed various research, teaching and conservation roles in the government, university and private sectors, and have advised various governments on managing communities of native and invasive animals.
