Alison Hayes is a Senior Research Fellow in health economics at the School of Public Health, University of Sydney, with a specialisation in health economic modelling of chronic disease. More specifically her work takes a life-course approach to projecting the consequences of chronic disease, with a strong emphasis on modelling the epidemiology of disease and its associated long term costs and quality of life outcomes. The models combine techniques of patient-level simulation with decision analysis for evaluating the cost-effectiveness of interventions. Alison is passionate about using models as translational tools to bridge the gap between cost-effectiveness evidence and policy decisions in public health.
