Jean-Louis DessallesAssociate Professor

Repères biographiquesShort Biography

Jean-Louis Dessalles is associate professor at Télécom Paris in the LTCI laboratory and a member of the DIG research team. He uses artificial intelligence to model and simulate the relevance that characterizes spontaneous human communication.

For a decade, he has been developing the Theory of Simplicity, which serves as a basis for modeling narrative interest and argumentative relevance. He also works on the simulation of evolutionary processes and on the fundamental question of the origin of human language, considered as a social signalling game. He is the author of several books, including Why We Talk (Oxford University Press. 2007), La pertinence et ses origines cognitives (Hermes), Le fil de la vie (Odile Jacob, 2016), Des intelligences TRÈS artificielles (Odile Jacob, 2019).

Academic background

Admitted to the École Polytechnique (Paris) in 1976, he graduated from Télécom Paris (then École Nationale Supérieure des Télécommunications) in 1981, received his PhD in 1993 and was awarded an HDR (habilitation to direct research) in 2008 at the Université Paris-Sorbonne.

Jean-Louis Dessalles’s research focuses on the fundamental principles underlying the faculty of language and its biological origins. In particular, he studies narrative interest and argumentative relevance, as well as the conditions that make honest communication between potentially selfish agents possible, in order to explain the emergence and evolution of language.
