The Crem (research center on mediations) is an interdisciplinary laboratory of the University of Lorraine. It includes 200 members, teachers-researchers, PhD and PhD students, and a support staff. Its researchers come from the University of Lorraine but also from other French and foreign academic institutions. They cover a wide range of disciplines including information and communication, language, art, literature, anthropology and sociology.

Their works question mediation and creation phenomena in their technical, organisational, political, intercultural, semantic, literary, esthetic and artistic aspects. Their main objectives are to analyze dynamics and relationships between standards and gaps in information and communication processes, and to better understand regulatory processes.
