I am a visiting Professor within the Department of Public Health and Clinical Medicine at Umeå University. In South Africa, I am a Chief Specialist Scientist at the South African Medical Research Council (SAMRC) and hold honorary Professorships at the Universities of Cape Town and Witwatersrand. I lead a research group that explores the non-communicable disease risk factors in Africans using a multi-disciplinary approach to characterize the involvement of genetic, molecular, physiological and lifestyle determinants and their interaction. A major focus of my research is to understand the pathophysiology of type 2 diabetes in Black Africans, which we have shown to be different to populations of European ancestry.
