Governance - IHES


“Theoretical sciences are some of the most powerful tools for understanding the world better.”

institut_gouvernance_gahoud“I know full well that fundamental research remains essential for industry. The power of the models designed by theorists regularly results in significant technological leaps. IHES is one of the few places in the world to offer the scientific community the environment in which research – necessarily free and curiosity-driven – can flourish. We should preserve this model and support its development.
The scientific method is driven by a desire to push the boundaries of knowledge, which is also a desire for independence and freedom – two of IHÉS’ core values. As well as the decisive part it plays in most technological innovations and its impact on economic players, basic research contributes to deep, universal thinking. Whether solving the mysteries of black holes or of morphogenesis, theoretical sciences are some of the most powerful tools for understanding the world better.
IHES is more than ever determined to fully play its part within the scientific ecosystem, by offering exceptional scientists a place where their research can flourish. Supporting the IHES model for the benefit of the entire scientific community is essential.”

Marwan Lahoud, President of the IHES Board of Directors

Board of Directors

IHES is managed by a Board of Directors, comprising a maximum of 18 members. Its membership consists of representatives of the State (the French Ministry of Research and CNRS), founder representatives, and individual members.

The Board of Directors meets twice a year:
– Spring session: scientific presentation, presentation, and approval of the previous financial year’s accounts, presentation of the revised budget for the current financial year, and presentation of various projects concerning the Institute;
– Autumn session: budget monitoring, approval of the following year’s budget, presentation of the various events which have taken place over the year.

Scientific Council

The Scientific Council has the prerogative of planning the Institute’s scientific work at its twice-yearly meetings. It comprises ex-officio members (the director, the permanent professors, the Léon Motchane professor) and external members who are co-opted for three-year mandates. CNRS Research Directors at IHES and the holder of the Université de Cergy-Pontoise – IHES Analysis Chair are also invited to take part in discussions. The Scientific Council is responsible for recruiting permanent professors, as well as selecting invited researchers and organising the programme of scientific events.

The Scientific Council meets every year in June and December to select future visitors and to debate the Institute’s scientific policy. Together with CNRS and CEA Research Directors at IHES and the holder of the Université de Cergy-Pontoise – IHES Analysis Chair, they select visitors on the basis of excellence alone and ensure that a balance is maintained between theoretical physics and mathematics.
