The school, École thématique CNRS, is devoted to braids and their different applications and aspects. This seventh edition of Winter Braids is supported by the Université de Caen I, GDR Tresses, GDR singularités, GDR GNC and Institut de Mathématiques de Bourgogne. Besides the main lectures, there will be short talks and a poster session devoted to student presentations (not necessarily focused on braids or their generalizations). This edition will be in honor of Patrick Dehornoy for his 65th birthday. All talks will be held in English. Practical informations are given on "Programme" and "Access" pages.
