I have worked on wildlife since the 1970s. Much of my research has been on macropods (kangaroos and wallabies), with a particular interest in eastern and western grey kangaroos where they overlap and form mixed-species mobs. I started with theoretical questions about behaviour and ecology, then moved into more applied issues, particularly the challenges of overabundance. I have also studied a range of other species including gulls, legless lizards, wombats and bandicoots.
I have written over 150 journal articles, 30 book chapters and 70 technical reports, and have spoken at over 100 conferences. I also am a member of ten advisory bodies and recovery teams. In recent years I've been working on non-lethal management methods: deterrence from roadways, fertility control and translocation.
