Leonie Tickle is Professor in Actuarial Studies at Macquarie University. Her research in longevity modelling and forecasting is at the forefront of new developments in the area and includes stochastic mortality modelling and forecasting methods; longevity risk; population ageing and the impact on economies; health and mortality; insurance; actuarial science; and mortality drivers. Her research is strongly interdisciplinary, and she has collaborated with a large network of colleagues in demography, statistics, data analytics, epidemiology, risk, economics, applied finance, public health, psychology, education and insurance.

Across almost 50 publications Leonie has published in the top international journals in the field, including Insurance: Mathematics and Economics, Population Studies. Demographic Research and Annals of Actuarial Science, where she co-authored the most highly cited paper in the journal’s history. Her research is also highly engaged, with a strong impact on practice. For example, her population and longevity forecasts revealed the conservatism of official projections: the important implications for government policy led to much media commentary and methods were later incorporated into official projections. Other methodological work has been adopted by the national statistical agency in Denmark for official forecasts. She led a national industry-funded research unit with responsibility for producing mortality analytics for the Australian insurance industry, used by actuaries in setting premiums and by the regulator. She has been awarded the H M Jackson and the A M Parker prizes for research.
