I teach and advise medical degree students, and train postgraduate research students in health services research methods. I have supervised thirteen PhD students to completion.

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. I collaborate with a wide range of clinicians and health researchers in the UK, South Africa, East Africa, South America and the United States, together producing multidisciplinary research and original evidence to help improve essential health care in low, middle and high income countries.

• Implementation research: how to get evidence into practice through complex interventions aimed at changing professional, organisational behavour, for example using education and clinical practice guidelines. What that means is illustrated here: http://knowledgetranslation.co.za/ (I have worked with the KTU continuously for 20 years).
