Gregoire studied statistics and development economics in France, and has been interested in the frontier between measurement, policy design and implementation. Working for five years in different sub-Saharan African countries’ health information systems, Gregoire witnessed firsthand how little health policies rely on a good understanding of available data. His research explores new ways to mobilize data routinely collected in health systems to inform management and strategic planning. This data is often overlooked because of availability and quality issues, even though substantial investments are made to collect it. This raises efficiency and equity issues, and his hope is that increased comprehension and use of this routine data by people working in health systems can improve their commitment and ability to collect the data they need. After graduation, he wants to keep working on strengthening the capacity of decision makers in low-resource countries to use data to design home-grown health interventions adapted to their populations’ needs.
