Prof Brian Williams, PhD

Research Fellow

Research Fellow

Dr Brian Williams, who helped to set up SACEMA with Prof Wayne Getz and Prof Ekkehard Kopp, is now retired having spent the last ten years of his working life in the World Health Organization. Since retiring he has continued to work closely with SACEMA and has been one of the main driving forces behind the use of anti-retroviral therapy to stop AIDS and prevent TB. He continues to be active in both teaching and research.
