My current research deals mainly with the nature, scope and modalities of intellectual cognition, as the question was posed historically in medieval university debates (13^th and 14^th centuries). I am also interested in problems of ontology and metaphysics, especially in the topic of universals, as well as epistemological issues involved in the question of the relationship between the philosophical and religious discourses. My publications almost always comprise three dimensions: the critical edition of Latin texts from the High and Late Middle Ages, the translation of these documents into French, and their interpretation and analysis from the viewpoint of a critical history of medieval thought.
