Research Interests


Physical Activity epidemiology in middle-aged and older women

In August of 2008 I joined the Cancer Epidemiology Unit at the University of Oxford as a Research Scientist in Physical Activity Epidemiology. I lead a program of research at the CEU on physical activity and health outcomes in the Million Women Study (MWS) cohort. I have considered the different effects of age, adiposity and physical activity on the risk of fractures at different sites in postmenopausal women. I have also considered the associations between physical activities and various vascular diseases including coronary heart disease, stroke and venous thromboembolism.




Nutritional Status, physical fitness and physical activity in children

I read for a PhD in Exercise Physiology at the University of Cape Town with Mike Lambert and Vicki Lambert on Youth fitness testing in South African primary school children. This project focused on the development of national normative data for physical fitness and nutritional status of South African children (6-13 years) and considered the effects of socioeconomic status on these factors. It also involved the development of the the South African "Health of the Nation" software (version 1.0) aimed at standardising and streamlining the collection, analysis and reporting of the health-related fitness of children according to South African normative data.

I still work in this area of research in collaboration with Professor Makama Andries Monyeki and a number of other international collaborators.
