L’IRME UQAT-Polytechnique à GeoOttawa 2017

Du 1er au 4 octobre se tient à Ottawa la 70e Conférence Canadienne de Géotechnique (GeoOttawa 2017 : geoottawa2017.ca). Etudiants, chercheurs et professeurs de l’Institut de Recherche en Mines et Environnement (IRME) UQAT-Polytechnique seront sur place pour présenter les dernières avancées dans de nombreux projets de recherche. Ce ne sont pas moins de 18 présentations qui sont ainsi programmées tout au long de la conférence (programme ci-dessous). N’hésitez pas à venir nous y rencontrer !

 Pour ne manquer aucune de nos présentations, voici l’horaire de nos interventions.
