Chair in Operational Research
Overview
I am part of the Operational Research group in the School of Mathematics at Cardiff University. Operational research (OR) is a way of using analytical methods to help make better decisions. I am committed to developing the role of OR in the Environment, Energy & Sustainability. For example:
- Sustainable water management
- Optimal production and distribution of renewable energy (tidal, hydo, wind, etc.)
- Risk quantification and disaster management (such as flood, drought and fire)
- Biological modelling for population management and disease control
Operational research draws on a wide range of mathematical modelling and optimisation techniques, and seeks to balance economic, environmental and social objectives. My background is mostly in stochastic modelling and simulation, and I am particularly interested in likelihood free methods for fitting complex stochastic models to data.

Research
I am an applied mathematician with a background in data analytics, optimisation and simulation. Many of my projects involve assembling data from divers sources, using it to build simulation models, then using those models to inform management decisions. Previous collaborators include the Australian Department of Agriculture, Fisheries and Forestry (planning for the Post Entry Quarantine facility, a national infrastructure project); the Australian Office of Transport Security (improving security procedures in Australian airports); Rate Valuation Services (a financial services company); McLaran International (the racing team); Merlin Power Systems (a feasibility study for an emergency response scheme for power generators in the UK); and National Air Traffic Systems (responsible for air traffic control in the UK).
My work makes use of a wide range of computational, analytical and mathematical techniques. I have taught graduate courses in machine learning and data mining, and I am the principal author of a best-selling text book on programming and simulation using the language R. Much of my current research concerns complex spatio-temporal environmental data, in particular problems of water runoff in catchment areas.

From the preface: “This book has two principal aims: to teach scientific programming and to introduce stochastic modelling. Stochastic modelling in particular, and mathematical modelling in general, are intimately linked to scientific programming because the numerical techniques of scientific programming enable the practical application of mathematical models to real-world problems. In the context of stochastic modelling, simulation is the numerical technique that enables us to analyse otherwise intractable models.
“Simulation is also the best way we know of developing statistical intuition.”
