Biography

Laurent BRISSON is Professor (Directeur d’études) at IMT Atlantique, in the Data Science department, where he serves as Deputy of Teaching and Head of the Data Science Program.

He received his Ph.D. in Computer Science from Université Nice Sophia-Antipolis (France) in December 2006, under the supervision of Martine Collard, working on the integration of expert knowledge into data mining processes to extract information relevant from a human expert’s point of view. He took up a position at IMT Atlantique (then Télécom Bretagne) in September 2007 and has been a member of the Lab-STICC laboratory ever since, first within the DECIDE team and now within the Complex Networks team. Early in his career, he also contributed to scoring models raising awareness of breast cancer risk in primary prevention populations, and worked on sentiment analysis for automatic comment classification.

His current research centers on complex networks and community dynamics in temporal graphs, including the detection of change points and the study of individual trajectories within evolving communities. He applies these methods to computational social science, notably the analysis of team interactions and echo chambers in social networks. More recently, he has extended this work to pedagogical AI agents, designing intelligent tutoring systems that combine deterministic pedagogical orchestration with large language models.
