On May 12, undergraduate students from UCLouvain presented at Metrolab Studio the result of a one-year inquiry on the issues of social/cultural diversity in Brussels, both in (1) urban public spaces and (2) in schools. This collective research was presented under the form of research posters and assessed by researchers from MLB and UCLouvain. Impressive work ! Many thanks to the students, Prof. Marie Verhoeven, the assistants (Nathan Gurnet, Yannicke Destexhe), the assessors (Edouard Gardella, Louise Carlier, Lionel Francou, Baptiste Veroone, Esteban Rosewajn, Jérôme Deceuninck) and to Sara Cesari for the organization.
