The Territories and Digital communities is a research group with an interdisciplinary and transdisciplinary approach involving collaboration with experts on computer ethics, economics, economic sociology, urban studies, geography, and pedagogy. In addition, we rely on professional expertise to help establish experiments in local social contexts through participatory design, community development, social policy, and diversity management. Interdisciplinarity and transdisciplinarity are strongly required to design and develop digital technologies that meet the needs of people and communities.
