Qualifications
BSc PhD W.Aust.
Biography
I obtained my PhD from the School of Animal Biology, University of Western Australia in 2001. I undertook postdoctoral research in Sweden, Wales and Scotland before taking up a NERC Research Fellowship at the University of St Andrews, UK. I returned to Australia in 2004 to commence an ARC Research Fellowship.
Key research
I am an evolutionary biologist who has conducted research in behavioral ecology, but also in evolutionary theory, conservation biology and genetics. I have research interests that cover a diverse range of topics including behavioral ecology, female ornamentation, evolutionary stable strategies, the evolution of colour signals, nuptial gift evolution, conservation genetics, developmental integration, selection analysis, mutational load and genetic incompatibility. I have also developed microsatellites and used them to assess population genetic parameters.
Current Projects:
- The maintenance of alternative male strategies in the painted dragon lizard
- Sexual selection on female phenotypes
- Gene flow, ultraviolet markings and sexual selection in the Tenerife lizard
- Quantifying fitness functions in the male dimorphic mite
