Cornell University is hosting the 4th Annual Summer Institute, from 24 July to 4 August 2017, which brings together experts from the World Health Organization (WHO), Cochrane, and Cornell University to train participants in the development of systematic reviews of nutrition interventions in populations. The program aims to update and develop your technical skills and knowledge in systematic reviews of nutrition and nutrition-sensitive interventions; build understanding of the process for global policy making, nutrition, and evidence assessment and its challenges; complete hands-on training in the development of Cochrane systematic reviews on a topic of immediate global health relevance in nutrition and public health; and develop confidence with the review methods and foster development of professional networks with fellow participants and faculty.
