The Assembly of Professors is the central governance body of the institute that defines the general strategy, the budget and management orientations of the institute. This assembly elects a director, assisted by a deputy director, in charge of directing the execution of the decisions taken by the Assembly of Professors, managing the translation of these decisions in concrete actions, representing the institute at the direction of the Faculty of Basic Sciences, within EPFL and elsewhere, and transmitting to the Assembly of Professors the information relevant to the institute coming from EPFL and elsewhere.
