As a mathematical epidemiologist, I work on mathematical models of infectious diseases, focussed on estimating the public health impact of new vaccines. The focus of my current research is to develop dynamic models to help inform longer term planning of ongoing COVID-19 vaccination programs in Australia and the broader region. To do this, I use mathematical models that account for the need for booster doses, properties and availability of current vaccines, the emergence of variants of concern, seasonality, and priority population groups.

Through my research, I aim to help guide ongoing country-level COVID-19 vaccine programs that align with the broader immunisation and health system priorities of individual countries. Sustainable and efficient COVID-19 vaccination policies will ultimately reduce the health and societal impact of COVID-19 for Australia and the region.

I also work on models for for respiratory syncytial virus (RSV) transmission and vaccination, to inform target product profiles for RSV vaccines. I have previously worked on estimating the public health impact of the RTS,S/AS01 malaria vaccine, supporting World Health Organization decision-making on the use of malaria vaccines in children, and on modelling the health impact of second-generation malaria vaccines in malaria endemic areas.

Prior to beginning this position at UNSW, I was a Research Fellow at the MRC Centre for Global Infectious Disease Analysis, Imperial College London (UK), where I hold an Honorary Lectureship position.
