I hold a faculty position at Université d'Artois.

I am a member of Faculté des Sciences Jean Perrin and I do my research at Centre de Recherche en Informatique de Lens
(CRIL-CNRS, UMR 8188.)

I am the head of the Master informatique, spécialité recherche «Systèmes intelligents et applications».

My research activities are mainly concerned with artificial intelligence (AI), and more specifically with knowledge representation in a broad sense. I have been working on a number of topics within this research area and related areas. This includes the  study of various forms of inference (especially abduction and induction), of several concepts of independence and notions of forgetting, of decision making (under its various types: multicriteria, uncertainty and group decision making), of preference representations, of action representations, etc.

For many years, I am specifically interested in two topics, namely reasoning under inconsistency (from several perspectives, including belief revision and belief merging, paraconsistent logics, argumentation), and knowledge compilation (in a nutshell, how pre-processing can be used

to improve AI tasks from a computational point of view.)
