Stochastic Modelling and Operations Research
Stochastic Modelling and Operations Research involves using mathematics to understand and make decisions in systems that involve randomness and/or uncertainty.
Based within the School of Mathematical Sciences, our Stochastic Modelling and Operations Research group fuses theory, computation and data to address exciting and important problems throughout the sciences and industry.
We have particular strengths in:
- modelling stochastic systems, particularly using computational techniques
- calibrating stochastic models
- modelling networks and their processes, with applications in energy and the Internet
- modelling in ecology, epidemiology and evolution
- Bayesian computational statistics
- data science.
The Stochastic Modelling and Operations Research group’s advances are of direct relevance and benefit wherever uncertainty and/or randomness exists. This includes, for example, industries and areas such as:
- the Internet
- cyber security
- power grids
- conservation science
- health care systems
- infectious disease epidemiology.
The Stochastic Modelling and Operations Research group has received significant recognition for its valuable contributions to industry and society, including prestigious medals from the Australian Academy of Science and Australian Mathematical Society.
Some recent real-world-impact highlights include:
- providing new epidemiological insight into influenza and seasonal epidemics through work with the Australian Sentinel Practices Research Network
- developing algorithms to estimate pandemic strains’ transmissibility and severity
- advising the Australian Government’s Office of Health Protection on pandemics, including the Australian Health Principal Protection Committee (AHPPC) on the COVID-19 pandemic
- developing tools for predicting events using open social media data, which are now being built into commercial forecasting tools for government use.
We have expertise across a wide range of areas. Many of our researchers are available to assist with research project supervision for Master of Philosophy and Doctor of Philosophy students.
