Our research on decision making under uncertainty is concerned with stochastic and robust optimisation within the context of uncertainty and risk. This involves modelling and optimisation of stochastic systems arising in engineering, defence, economics, finance, project management and supply chain management, etc. In particular, we research on worst-case design and risk management, scenario analysis, stochastic performance modelling and evaluation of computing network models.

A particular aspect of decision making under uncertainty is that of information collection. If additional information can be collected, but at a cost, how should the effort be spent to reduce the uncertainty where this is most beneficial to decision making in the future.
