Our Carnot institute ISIFoR had the pleasure to celebrate its 10th birthday without health restrictions. This long-awaited event has been held in the Palais Beaumont of Pau on March, 17th and gathered a hundred people. This festive and professional day was structured around oral presentations of our parent institutions and researchers, a networking lunchtime cocktail and a roundtable dedicated to the role of the subsoil in the energy transition.
