Prior to arriving in Melbourne, I was a member of the (former) Science and Engineering of Natural Systems Group, University of Southampton, working with Prof Seth Bullock (2007-2010). I obtained my BSc (2001) and PhD (2006) in computer science at the School of Information Technology and Electrical Engineering, University of Queensland, supervised by Prof Janet Wiles.
Current CV (July 2016).
I am currently a CI on a National Health & Medical Research Council Centre of Research Excellence on Policy-Relevant Infectious Disease Simulation and Mathematical Modelling.
My current research concerns:
Prior to arriving in Melbourne, I spent a few months on a bike.
