Qualifications: PhD
Research Group: Centre for Cardio-metabolic Research in Africa (CARMA)
Research Focus: The involvement of the ataxia-telangiectasie (ATM) protein in the development of a diabetic cardiomyopathy. The role of mitophagy during ischaemia and reperfusion of the heart in obesity related insulin resistance and the potential of melatonin to influence these processes. Fractionation of extracts of Cyclopia species and their potential anti-obesity properties (in collaboration with Dr C Pheiffer at the MRC). The possible use of substances isolated from Aspalatus linearis as anti-diabetic and cardioprotective substances (in collaboration with Dr R Johnson at the MRC).
