I am a Professor of Applied Mathematics in the School of Mathematical Sciences at the University of Adelaide.

My research is focused on developing novel mathematical and statistical methods, and new probabilistic models, that assist in understanding the factors that are most important to complex systems in epidemiology and conservation biology. I use these techniques to assist in determining effective public health, and conservation/biosecurity, policy.

Research Interests: Data Science; Mathematical modelling in Ecology, Epidemiology and Evolution; Stochastic modelling; Bayesian computational statistics; Operations Research; Outbreak Analytics.

 

SA COVID-Ready modelling

I am the lead modeller for the SA Government's COVID-Ready modelling. With Dr Thomas Prowse we have undertaken modelling to support decision making regarding COVID-19 in South Australia.

Delta and Opening Borders

We first undertook modelling concerning the Delta variant and scenario planning to inform the policy settings that should be in place when opening borders following reaching 80% (16+) vaccination coverage, and for 90% (12+) vaccination coverage. The 80% report is available here.

A video explaining this work from the SA Chief Public Health Officer Prof. Nicola Spurrier is below.

 

Omicron and Rapid Response

During the third week post-opening of borders it became evident that cases were not tracking as expected for Delta, and the possibility of the emergence of newly-declared variant of concern, Omicron, was investigated. This led to modelling to inform rapid response.

Details of this can be found here, including another video explaining this work by Prof. Nicola Spurrier 

 

Lifting of Activity Restrictions

Most recently, I have been modelling the impact of lifting of activity restrictions, vaccination numbers, and other changes to Transmission Potential on cases and hospitalisations in South Australia.

Please find further released details here.

 

Throughout, this work has been reported to the SA COVID Transition Committee, and the SA COVID-Ready Committee, and has involved a collaboration with SAHMRI and SA Health. The work has supported decision making around Activity Restrictions, School opening, and Health System Capacity provisioning (e.g., see here).
