Personal profile

Biography

2004 PhD Behavioural Ecology, Cambridge University, UK
1999 BSC (Hons) Animal Ecology, Lincoln University, New Zealand

After finishing my PhD, I was awarded a postdoctoral position at Newnham College, Cambridge University. During this time I set up the Pied Babbler Research Project in the Kalahari desert. In 2005 I took a postdoctoral position at the University of Cape Town, and then moved to a research position at Macquarie University, Sydney, in 2009. I moved to UWA in 2012 as an ARC Future Fellow.

Future research

My Future Fellowship research involves investigating the long-term population dynamics of two wild, cooperatively breeding bird species. I will use these populations to investigate critical group size effects (i.e. the demographic and behavioural changes that occur when groups become too big or too small).

The research funded by an ARC Discovery grant will investigate group dynamics in the cooperatively breeding Western Australian magpie. A specific aim of this research is to understand how group-living affects the development and expression of cognitive behaviour, and what the consequences of variation in cognitive ability are.

Research

My main interests lie in the field of behavioural ecology. I am particularly interested in the evolution and dynamics of cooperative breeding behaviour. My research involves understanding the causes of helping behaviour, and the costs and consequences of such behaviour. I have an increasing interest in long-term population dynamics, host-brood parasite interactions in cooperative systems, and the complexity of interspecific interactions. I also work at the interface between behavioural ecology and conservation biology - using behavioural information to provide more informed conservation decisions.
