Research administration

K. Belabas is the head of the mathematics department of University Bordeaux 1. He also leads the computer science support service (“cellule informatique”) of the Institute of Mathematics of Bordeaux and coordinates the participation of the institute in the regional computation cluster PlaFRIM.

He is a permanent invited member of the councils of both the math and computer science department (UFR) and the Math Institute (IMB).

J.-P. Cerri is an elected member of the scientific council of the Mathematics Institute of Bordeaux (IMB) and responsible for the bachelor programme in mathematics and informatics.

Since January 2011, J.-M. Couveignes is involved in the GDR mathématiques et entreprises and in the Agence pour les mathématiques en interaction avec l’entreprise et la société.

Until October 2013, A. Enge was responsible for the international affairs of Inria–Bordeaux-Sud-Ouest. As such, he was a regular member of the COST-GTRI, the Inria body responsible for evaluating international partnerships. Since October 2013, he heads this committee.
