I am a demographer and epidemiologist whose main research focuses on the epidemiology and demographic impacts of HIV in generalized epidemics, particularly its relationship with fertility and the modelling of paediatric HIV. My work also examines causes of death and cause-specific mortality patterns using verbal autopsy methods. I specialise in the analysis of large, complex population and health datasets.

I hold an undergraduate degree in Physics from University College London and an MSc in Medical Demography and a PhD on the demographic determinants of paediatric HIV from LSHTM. Prior to joining LSHTM in 2001, I worked at the Association for Health and Environmental Development (AHED), an NGO based in Cairo, Egypt.

I am currently the LSHTM lead on an ESRC-funded project investigating sociodemographic variation in childhood causes of death across Eastern and Southern Africa.
