I studied for a Bachelor of Science at the University of Queensland (UQ), graduating with first class Honours in computer science in 2001. Continuing at UQ, I gained a PhD in complex systems simulation in 2006, supervised by Prof Janet Wiles. During my PhD I used computational simulation models to investigate the role that developmental constraints play in orienting evolutionary processes. Between 2007 and 2010 I was employed as a researcher with the Science and Engineering of Natural Systems Group at the University of Southampton, working with Prof Seth Bullock to develop simulation models of dynamic processes on social networks.

In July 2011, I joined the Melbourne School of Population and Global Health, where I am part of the Modelling and Simulation group in the Centre for Epidemiology and Biostatistics, where I am supported by an Australian Research Council Discovery Early Career Researcher Fellowship. I am a CI on a National Health & Medical Research Council Centre of Research Excellence on Policy-Relevant Infectious Disease Simulation and Mathematical Modelling.

I will take up a position as Senior Lecturer with the Department of Computing and Information Systems at The University of Melbourne in October 2016.
