PhD Biochemistry (University of Venda, SA, 2016)

Msc Molecular Biology (Staffordshire University, UK,2012)

Honours in Bachelor of Medical Laboratory Sciences (University of Zimbabwe, ZW, 2005)

Research Summary

The Zininga Group focuses on investigating the role of molecular chaperones in protein folding in cells under stress. Our main focus is on the malaria agents Plasmodium spp. The parasites are dependent on a robust protein folding machinery for their survival in stressful environments. We hope to understand the parasite protein folding system and we intend to apply the knowledge to other diseases.
