I have a background in medicine (MD) and obtained my PhD in health economics from the University of Adelaide (2007). My main area of expertise relates to the economic evaluation of new health technologies with a focus on the application of decision analytic models aiming to improve  the decision-making process around the public funding of health care interventions.
In terms of applied economic evaluations, my major research activity is the design, conduct and analysis of economic evaluations alongside observational studies and clinical trials. This also includes the application of decision analytic models to extrapolate the findings beyond the observed data in order to estimate long-term costs and outcomes of new health technologies. The main focus of my methodological research is on the improvements in the decision-making process with a view to better inform public funding decisions. Examples include the development of diseases-specific reference models, model structuring (including structural uncertainty) and the estimate of the cost-effectiveness threshold in Australia.
Since 2020, as a chief investigator, I have received over $25 million in research funding from competitive grants. I am coordinator of health economics courses within undergraduate and postgraduate public health teaching programs at Adelaide University. Previously (2019-2023) I was coordinator of all postgraduate public health teaching programs (including MPH) at Flinders University.
For 9 years I was a member of the Evaluation Sub-Committee (ESC) of the Medical Services Advisory Committee (MSAC) (2015-2023) whose role is to advise the Australian government on evidence relating to the safety, effectiveness and cost-effectiveness of new medical technologies and procedures. I was also an evaluator of submissions to the Pharmaceutical Benefits Advisory Committee (PBAC) to determine funding of medicines (2007-2009). I have also been involved in revising MSAC and PBAC Guidelines.
