Prof Wendy Stevens

Wendy Stevens is a leading South African academic in molecular diagnostics and public health, widely associated with the National Health Laboratory Service and the University of the Witwatersrand. Her work has shaped the integration of laboratory innovation into national HIV and tuberculosis programmes, strengthening diagnostic networks and access to care across high-burden settings.

Her research centres on evaluation and implementation of molecular assays for tuberculosis, drug resistance, HIV monitoring, and emerging infections. Recent studies assess novel platforms such as Xpert and cobas systems, non-sputum sampling strategies, and integrated TB–COVID testing, demonstrating strong expertise in diagnostic accuracy, laboratory systems, and real-world feasibility.

A parallel focus on health economics and programme impact is evident in analyses of cost-effectiveness, return on investment, and national diagnostic strategies. Contributions to lymphoma outcomes in people with HIV and hospital-based HIV care trends further reflect a commitment to linking diagnostics with clinical outcomes and health system performance in sub-Saharan Africa.
