Research Interest  
Operational research to improve the prevention of mother-to-child transmission of HIV programs in resource-constrained settings
Molecular mechanistic pathways of mother-to-child transmission of HIV

Dr. Joel Njah is a Global Health Fellow and a research associate in the Department of Environmental and occupational health at the Graduate School of Public Health, University of Pittsburgh. He is currently enrolled in the PhD program in Clinical and Translational Science at the University of Pittsburgh. His research focus is in the role of bone marrow mesenchymal stem cell (MSC)-derived extracellular vesicles in mitigating fibrotic lung diseases, including idiopathic pulmonary fibrosis and silicosis. As a global health fellow, his interest is in operational/implementation research to improve prevention of mother-to-child transmission of HIV programs in Sub-Saharan Africa (SSA). He was formerly a primary health care/family medicine practicing physician for over six years in different resource-constrained and underserved regions of SSA.
