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 study the descriptive epidemiology of various NCDs, with emphasis on the role of public health and clinical interventions in disease trends and patterns. We work closely with the World Health Organization, and are designated as the WHO Collaborating Centre on NCD Surveillance and Epidemiology.
