The Population Child Health
Research Group

Our vision is to improve the lives of children by discovering the factors affecting their health and wellbeing. We conduct translational research to improve health systems, and aim to develop, implement, and evaluate scalable interventions that can be delivered by existing practitioners.


We're a multidisciplinary team striving to understand poor health in children and young people. We focus on translating our findings to clinical practices that will improve the lives of children. Our research addresses three key themes: Integrating Care, First 2000 Days, and Priority Populations.
