Jean-Noël Senne was invited at the seminar “Premiers Pas” at the University of Bordeaux on March 28th, 2019. He presented feedbacks and a review of findings from the MIDDAS project. This project, funded through the ANR (2009-2012), aimed at collecting multi-sited and matched data among both Senegalese migrants and their origin families back home to investigate the impact of migration on development in the home country.
