About

We are a happy and extremely productive research group. We place a strong emphasis on creating a friendly working environment. If you thrive best in a winner takes all setting then we are not for you. If, however, you enjoy biology, like working with animals and find evolution fascinating then read on. We value and strive for research excellence. Ultimately scientists are evaluated on what they publish - avoid the hype and just check out our publications. If you are considering Honours, a PhD or Post-doc and want to produce high quality work with a view to pursuing a career in biology then please get in touch.

What do we do? We are interested in whole organism evolutionary biology, especially the evolution of behavioural and morphological reproductive traits. Our main focus is testing sexual selection theory. The kinds of questions we ask are:

  • Is there a trade-off between diets that maximize mating as opposed to fertilization success?
  • How does inbreeding affect sexually selected traits versus other traits?
  • Why do females mate multiply?
  • What affects the offspring sex ratio?
  • Are males more variable than females in their behaviour?
  • Does winning a fight increase your future likelihood of winning another fight?
  • Are older more succesful because they are more sexually experienced?
  • What determines the rate of sperm production? 

We conduct: behavioural ecology experiments, artificial selection studies, and meta-analysis of literature.

We use: immunological assays, diet manipulations, paternity analysis, and sperm assays.

We have conducted research on: fish, crickets, beetles, fiddler crabs, and humans.
