My research focuses on strengthening immunisation systems, improving vaccine delivery, and advancing maternal and child health in low‑resource settings. I work at the intersection of implementation science, health systems, and community engagement, with a special interest in reaching zero‑dose children and improving the resilience of primary healthcare during crises.
Much of my work involves collaborating with governments, partners, and frontline health workers to generate evidence that informs policy and improves the quality, accessibility, and equity of vaccination programmes across Africa.
