Career

I am an academic public health physician, clincial epidemiologist and health services researcher. I have worked in 4 medical schools, in the UK (Bristol, UEA) and South Africa (Cape Town, Free State), doing epidemiological and health services research, and teaching public health and research methods to medical and postgraduate research students. 

As good primary health care is a foundation of good population health, my research is mostly focused on innovation, integration and evaluation of primary health care, for HIV/AIDS, tuberculosis, respiratory disease, diabetes, hyperension, depression and other long term conditions.   When I was a medical student and junior doctor in 1980s South Africa, I was active in anti-apartheid student and health politics. This led me into occupational health and safety, consulting and doing epidemiological research for non-racial trade unions. With the demise of apartheid I realised that great health benefits could come from expansion and strengthening of public sector primary health care. So I switched to health services research.

After public health specialist training in South Africa and the UK I learned more from British health services researchers and public health colleagues . The NHS encourages experimentation and is responsive to health services research evidence, which it funds well. This makes the UK a world leader in the research methods I use, such as the evaluation of complex interventions with cluster randomised trials, cost effectiveness evaluation, and interdisciplinary mixtures of epidemiology, economics and social science.  It is a privilege to be based in this scientifically excellent setting while helping my committed colleagues to tackle the health care challenges of high, middle and low income countries.
