I collaborate most frequently with Lindell Bromham, John Welch (Cambridge), Rob Ray (Sussex), and Simon Ho (Sydney). My software development is done in collaboration with Brett Calcott (ANU) , Stephane Guindon (Auckland), and Alexis Statmatikas (Karlsruhe).
Before coming to Australia I did a short postdoc with Max Telford, working on the shrimp Parhyale hawaiensis, and a PhD on the evolution of segmentation at the University of Sussex (UK).
