At the core of the CHILD Cohort Study’s governance and administration structure are a Director, Co-Director and an Executive Committee comprising the site leaders and research theme leaders.
The decisions of the Executive Committee are informed by input from a Scientific Advisory Committee, and its work complemented by that of various Scientific Working Groups and Sub-Committees.
On-the-ground implementation of the Study is undertaken by teams at each of the four Study sites, under the coordination of a National Coordinating Centre–within which Study data and biological samples are centralized and managed.
