Dr. Leena Thomas

Leena Thomas is a public health researcher whose work centres on strengthening primary health care systems in South Africa, with particular emphasis on community health worker programmes and universal health coverage. Her scholarship is closely associated with urban district health services, especially in Gauteng Province, where she has examined large-scale system reforms aimed at improving access for vulnerable populations.

Her publications highlight the design, implementation and evaluation of comprehensive community health worker models in metropolitan settings. Through quasi-experimental and cross-sectional studies, she has demonstrated how sustained outreach teams enhance early screening, chronic disease management, maternal and child health, and access to social support. This body of work provides important empirical evidence for integrating household-level services into formal health systems in low- and middle-income contexts.

Beyond community health systems, Thomas has contributed to research on district hospital capacity, procedural skills of clinicians, health leadership, and decentralisation. Her interdisciplinary portfolio also includes urban health and wellbeing measurement, reflecting an interest in how built environments influence health. Collectively, her work advances policy-relevant knowledge on equitable service delivery, health systems governance, and contextually intelligent leadership.
