We use an integrative approach to understand costs and benefits of attributes of animals, combining observations with experiments and comparative studies. One of the main research themes concerns the mechanisms that govern trade-offs between key life-history components: how do animals balance investment in the pursuit of mating opportunities, parental care and their own health. 
Research in the group focuses on behaviour, physiology and evolutionary ecology of wild birds. Currently, our main field projects involve long-term studies of purple-crowned fairy-wrens, Malurus coronatus in the Kimberley region of north-west Australia, and a local population of superb fairy-wrens (M. cyaneus) at Lysterfield Park.
