Pierre-Yves Schobbens graduated in Philosophy in 1982, in Applied Mathematics and Economy in 1983, in Computer Science in 1984, magna cum laude from Univ. Cath. de Louvain, Belgium. He first worked there as researcher in the team of Prof. Sintzoff, on Formal Methods in Software Engineering, and Artificial Intelligence. He received grants for research stays at the Univ. of Passau and at the "Laboratoire d'Informatique Fondamentale et d'Intelligence Artificielle" (LIFIA, Grenoble where he took part in the development of the executable algebraic specification language LPG.

He obtained his Ph.D. in Computer Science in 1992, with a thesis entitled "Exceptions in Algebraic Specifications" showing applications of non-monotonic reasoning to software specification. He then worked as a Senior Researcher at CNRS in the "Centre de Recherche en Informatique de Nancy (CRIN)". He is currently Professor in Artificial Intelligence at the Univ. of Namur (FUNDP).

He set up the HCM Network "Medicis" (on methodology for specifications) and the Esprit WG "ModelAge" (on the agent paradigm). He is the leader of the Namur team of the projects «CAT» (Walloon Region), Esprit WG «Aspire», Esprit WG «Fireworks», European-Canadian «Cooperative IS », «Renoir» Network. He is (co-)author of 37 papers, 1 book, editor of 4 proceedings.

His research interests include extensions of algebraic specifications towards agent- and object-oriented concepts (concurrency and inheritance), non-monotonic reasoning, formal requirements specifications, tool support for these activities.
