Sarah Njenga

DPhil Student

Passionate about using economics to inform evidence-based decision making for health policy in resource-constrained settings. 

Sarah joined the Health Economics Research Centre (HERC) in October 2022. Her research will conduct health economic analyses to understand the impact of non-adherence to paediatric oncology treatment in LMICs. This will include an examination of the societal costs of cancer care, and an economic evaluation to assess the cost-effectiveness of an ongoing holistic support programme in Korle Bu Teaching Hospital (KBTH) in Accra, directly targeting non-adherence. Capturing these insights may provide valuable evidence into the societal cost of childhood cancers on the patient and their families, and highlight cost-effective interventions which could decrease levels of treatment non-adherence for patients with chronic illnesses. Her DPhil is funded by Exeter College, under the Academic Futures Graduate Scholarship. 

Prior to starting her DPhil, Sarah obtained a BA (Hons) in International Relations with Economics from the University of Birmingham, and an MSc in International Development from the London School of Economics and Political Science, where her MSc dissertation focused on an analysis of accountability mechanisms for health insurance uptake in Rwanda. 

Sarah has research and management experience in the academia and consulting sectors, gaining experience in designing and implementing health projects with the International Decision Support Initiative (iDSI), and the School of Public Health, Imperial College London.
