• Lecturer, Department of Physiology, University of the Witwatersrand

Siphiwe completed his PhD in Paediatrics at the University of the Witwatersrand in 2021 and also holds an MSc (Biochemistry) from the University of KwaZulu-Natal.

His research interests include public health and nutrition, especially the importance of food nutritional labeling and the health impacts of food insecurity.
Siphiwe also investigates biological mechanisms of nutrition-related chronic diseases, particularly the role of body fat distribution and skeletal muscle mass.
