Ephraim Ziwoya

Ephraim Ziwoya is a Biomedical Engineer from Malawi and an MSc candidate in Water Science, Policy and Management (2025-2026). His work focuses on understanding water systems as integrated socio-technical and environmental systems that shape public health outcomes in low- and middle-income countries. His current research examines whether rural piped water systems reduce diarrhoeal mortality across Sub-Saharan Africa and South Asia. He investigates how service quality moderates the relationship between infrastructure expansion and health outcomes. His work adopts a systems and risk-based perspective, recognising that health risks are not determined by infrastructure alone, but emerge from the interaction between water quality, service reliability, environmental variability, and management practices. He is particularly interested in how data and interdisciplinary approaches can inform policy and investment decisions to strengthen water service delivery systems. His broader interests include water security, climate resilience, and advancing equitable access to safe and reliable water services.
