We coordinate Non-Communicable Disease Risk Factor Collaboration (NCD-RisC), a global network of health scientists and practitioners who collaborate to provide rigorous and timely global data on risk factors for NCDs. We also are a partner in NCD Countdown 2030, an independent collaboration to inform policies that aim to reduce the worldwide burden of NCDs, and to ensure accountability towards this aim, especially towards SDG target 3.4. We also study the variations in NCDs across populations and over time, to better understand the role of public health and clinical interventions in disease trends and patterns. The work is done in close collaboration with the World Health Organization.
