My research lies at the interface of actuarial science, mathematical finance and operations research, with a particular interest in mathematical models for long-term financial decision-making under uncertainty.

Much of my recent work has focused on collective pension schemes, investigating how longevity and investment risks can be shared fairly and efficiently between generations. This research develops risk-sharing theory, and draws on stochastic modelling and optimisation, to address practical questions in pension design and management.

Before entering academia, I worked in pension consulting, and I retain a strong interest in developing mathematically rigorous models that are relevant to practitioners and policymakers.

I am a professor of actuarial mathematics at Heriot-Watt University, in the Department of Actuarial Mathematics & Statistics.
