Dr. Sagie Pillay

Sagie Pillay is a public health researcher associated with health economics and infectious disease policy in South Africa, with links to leading academic and research institutions such as the University of the Witwatersrand. The work is situated within national efforts to strengthen tuberculosis control through evidence-based planning and resource allocation.

Published research examines the economic and programmatic impact of scaling up molecular diagnostics for tuberculosis, particularly GeneXpert MTB/RIF. Through population-level decision modelling and analysis of national TB data, the work evaluates how diagnostic innovation influences case detection, treatment initiation, and health system costs, offering policy-relevant insights for large-scale implementation.

Based on limited available publications, the scholarly contribution centers on health systems modelling, cost-effectiveness analysis, and implementation research in high-burden settings. The research supports strategic decision-making in TB control and highlights the balance between expanded diagnostic capacity and sustainable financing within public health programs.
