Research interests

I'm a conservation biologist interested in how animals respond to environmental change. I'm something of a details person and like to find out about the processes operating in animal populations and how they respond to environmental changes. I do a lot of field-based research, but often resort to genetic methods to study the things that animals don't tell us in other ways.

Researcher's projects

My current projects:

How does ecological disturbance influence genetic diversity and population viability? I conduct research on how the regimes of natural disturbances like fire influence the genetic diversity and population persistence of animals (and one plant!). The importance of major ecological disturbances like fires is widely appreciated, but we don't really know how natural populations (especially of animals) respond to these events. I am interested in how natural populations of animals and plants cope with disturbances like fire, how they will persist under changing fire regimes, and how patterns of fire shape genetic diversity in natural populations. This research involves simulation modelling and empirical research focussed on Victorian mountain ash forests, Jervis Bay coastal heathland and Kimberley savannah.

Marsupial conservation biology in montane forests. I conduct research on the ecology and conservation of arboreal marsupials in Victorian mountain ash forests (with Prof David Lindenmayer) and in the montane forests near Canberra. This research involves understanding the environmental and biological processes driving long-term changes in forest structure and animal abundance in these ecosystems.

Reintroduction genetics of native mammals. I conduct research to inform the genetic management of reintroduction programs for native mammals including bettongs, quolls , native rodents and bandicoots at Mulligans Flat Woodland Sanctuary in the ACT, and Booderee National Park.

How can we use genetic analyses to understand animal population biology? Biologists increasingly use genetic methods to study how natural populations work. I'm interested in testing how genetic analyses can be used to infer dispersal strategies and other biological processes, using both simulation-based investigations and empirical study. An example of a current project in this area is the PhD research of Yusuke Fukuda combining the use of genetic and stable isotope data to identify movement patterns of saltwater crocodiles around northern Australia to inform conservation and management.

Available student projects

I would be happy to talk to interested potential students about projects within any of my research areas. In particular, there are opportunities for PhD research in the field of genetic management of animal reintroductions.
