IMU Executive Committee

The International Mathematical Union is administered by an Executive Committee (EC) which, in accordance with the IMU Statutes and subject to the direction and review of the members, conducts the business of the Union.

The IMU Executive Committee consists of ten voting members elected for four-year terms: the four officers (President, two Vice-Presidents, and Secretary General) and six Members-at-Large. The IMU General Assembly 2006 in Santiago de Compostela increased the number of members-at-large from five to six. The retiring president is an ex-officio member of the IMU Executive Committee without vote for a period of four years.

The current members (term January 1, 2023 to December 31, 2026) of the IMU Executive Committee are listed below. The above photo (credit: Christoph Assmann) was taken on the occasion of the first meeting of the current term, held in March 2023 at the IMU Secretariat in Berlin, Germany.
