Chris Johnson is an ecologist who mainly studies Australian mammals with the aim of improving management of threatened and invasive species.
He began his career studying the behaviour of kangaroos and wallabies, and has since done research on many threatened mammals, including the greater bilby, northern hairy-nosed wombat, northern bettong, Tasmanian devil and others.
Chris also does research on extinctions of large animals, environmental change and human impacts from the time that people first arrived in Australia around 50,000 years ago. Among other scientific publications he has written an influential book on the history of extinction of Australian mammals over that whole period.
Chris has worked with the Queensland National Parks and Wildlife Service and James Cook University as well as the University of Tasmania.
