Our lab studies the evolution of recombination and host-pathogen coevolution. We mainly develop mathematical models and conduct evolution experiments with bacteria. We are part of the School of Biological Sciences at The University of Queensland. Please browse our website to find out more about our research, who we are and possibilities to join our group!

Looking forward to exciting years of well-funded research!
