I am a medical doctor by training. After five years in clinical medicine, I moved into the broader field of public health.
This included seven years in South Africa where I worked on the post-apartheid transformation of the country's health systems as well as numerous public health programmes. On return to the UK, I have worked variously as a public health practitioner and academic - both in the NHS, and on the global health terrain.
I have a doctorate from the London School of Hygiene and Tropical Medicine.
I currently also work as the Director of a UK-based public health charity called Medact.
