Executive Team

Dr Alexio Capovilla

Chief Scientific Officer


BSc(Hons) (Molecular Medicine and Haematology) – University of the Witwatersrand.

Ph.D. (Molecular Biology) – University of the Witwatersrand Medical School.

P.D.M. – Wits Business School.

Summary of Experience

In 2005, Alexio was appointed to the Department of Molecular Medicine and Haematology and co-director of the HIV Pathogenesis Research Laboratory (HPRL). Here he used extensive experience gained in virological research to pursue a budding interest in the biology of HIV.


At HPRL, he began investigating various aspects of the mechanism of HIV-1 entry into host cells, research that is directly applicable to the development of novel HIV-1 therapeutic compounds, vaccine immunogens and recombinant diagnostic products.


Alexio’s research career has involved temporary positions at collaborating laboratories in France (Laboratoire du Radiosensibilite, Commisariat a l’Energie Atomique (CEA), Paris) and Sweden (Medical Biochemistry and Biophysics, Medical Nobel Institute, Karolinska Institutet, Stockholm).
