Laurent Tessier has been a teacher-researcher in the Faculty of Education at the Institut Catholique de Paris (ICP) since 2005. He was dean of this faculty, then vice-rector of the ICP, with particular responsibility for the “digital campus” and “responsible campus” projects (inclusivity, sustainability).

For several years, he has been involved in the digital humanities movement. In 2016, he and Michael Bourgatte co-organized the first edcamp in France, which resulted in an original collective publication (Quelles humanités numériques pour l'éducation, éditions MkF, 2016). Also with Michael Bourgatte, he co-hosts the science blog Celluloïd, which reports on research and experimentation involving digital tools and contemporary educational issues.
