Areas of expertise Research Interests:

1. Bayesian statistical methods for combining evidence from different sources, and assessing evidence consistency. Examples include: synthesis of incidence and prevalence data for toxoplasmosis; estimating Markov transition parameters from various data sources that may include different forms of censoring, as well as exact event history data.

2. Comprehensive cost-effectiveness analysis where the inputs to the decision analysis model are the outputs from an evidence synthesis. Examples include: interventions to increase attendance at breast cancer screening; genetic testing to aid choice of pharmacological interventions for smoking cessation.

3. Expected Value of Information methods for research prioritisation and trial design. Examples include: cluster randomised trial for interventions to increase attendance at breast screening; mixed treatment comparison of treatments for bipolar disorders.
