Sylvia Medina is an epidemiologist dedicated to improving public health through research on the effects of air pollution on health, with special emphasis on the practical application of her work. In particular, the projects she coordinates seek to understand and cross the last mile that too often separates scientists and their findings from the minds and actions of policy makers, health professionals and the public. Dr. Medina currently coordinates the French Surveillance Program on Air Pollution and Health of the French public health agency (Santé publique France). She previously coordinated European and International activities on Environmental Health, including health impact assessments of different environmental risk factors under the WHO-EC ENHIS program; the APHEIS project on air pollution and health in Europe; and the APHEKOM (Improving Knowledge and Communication for Decision Making on Air Pollution and Health in Europe) project www.aphekom.org. Sylvia Medina has coordinated the ERPURS project at the regional health observatory (ORS Ile de France) in Paris, the first surveillance program on urban air pollution and health. After earning her MD at the University of Malaga, Spain, Dr. Medina received her MSc in epidemiology from McGill University in Montréal and her PhD in public health from René Descartes University in Paris. Among others, Dr. Medina was awarded for APHEKOM as one of the “Best projects funded under the European Union Health Programme” 2008-2013.
