I am an honorary research fellow at Imperial College London. My research interests focus on the use of quantitative and qualitative methods to support evidence-informed programs and policy. This includes the use of mathematical modelling, case study investigations and policy analysis. This work has largely focused on the estimation and projection of HIV epidemic trends and the impact of HIV interventions, including the investigation of the use of modelling and data to inform decision making for HIV prevention and policy.
Previously, I was the Research Manager for the secretariat of the UNAIDS Reference Group on Estimates, Modelling and Projections (www.epidem.org). This group advises UNAIDS and other international organisations on the methods used to estimate the national and global burden of HIV.
