Professor of Global Public Health, International Institute for Global Health (UNU-IIGH), United Nations University

I am a medical doctor by training. After five years of clinical medicine in England and South Africa, I moved into the broader field of public health.

I spent ten years working in South Africa where I supported the post-apartheid transformation of the country's health systems. On return to the UK, I have worked variously as a public health practitioner and academic - both in the UK and across the global health terrain. I am a former borough Director of Public Health in London, and former Director of the UK-based public health charity, Medact.
