I am Associate Professor and Head of the Health Economics Division in the School of Public Health & Family Medicine. I served as Director of the Health Economics Unit (2012-2017), and as Convener of the MPH Health Economics track (2005-2009). In 2016, I initiated and led the development of the new Postgraduate Diploma in Health Economics. I convened this new programme in 2016 and 2017.
My training is in economics and health economics, and I have worked on economic evaluation of health care interventions, economic considerations in vaccination, and scaling up health interventions since 1997. Current research focuses on the evaluation of cost-effectiveness of alternative diagnostic and treatment interventions for TB, HIV and cancer. I have published widely in high impact journals and my work has directly influenced government policy. I am involved in a wide range of research activities, often in collaboration with other national and international research groups, including the Global Health Cost Consortium aiming to estimate and analyse HIV, TB and other health service costs globally (https://www.ghcosting.org).
I have extensive teaching and student supervision experience. I teach Theory and Application of Economic Evaluation in Health Care on the MPH, and tutor Economic Evaluation for Health Care Decision Making on the Postgraduate Diploma in Health Economics. My doctoral students are studying topics including the cost and burden of adverse drug reactions associated with drug-resistant TB treatment, economic evaluation of models of prevention of mother to child transmission of HIV intervention, and universal public finance for early detection of breast cancer. As of June 2018, 4 PhD and 30 Masters students have graduated under my direct supervision.
I am an executive member of the Pharmaceutical & Technology Clinical Management Association (PTCMA) of South Africa, with a focus on research and education. I have served as a member of the WHO Immunization and Vaccines related Implementation Research Advisory Committee.
