The ICM Structure Committee for ICM 2026

The ICM Structure Committee is responsible for the structure of the Scientific Program of the ICM. In particular, it decides, among others, on the number of plenary lectures, the sections and their precise definition, the target number of talks in each section as well as other kinds of lectures, and the arrangement of sections.

The first ICM for which the ICM Structure Committee conducted its work was ICM 2022. A new ICM Structure Committee has now been constituted, which will be responsible for the scientific program of ICM 2026. The selection of the speakers will remain with the Program Committee.

Membership of the ICM Structure Committee for 2026 is as follows:

Terence Tao [Chair]
Hiraku Nakajima [IMU President, ex officio]
Nalini Anantharaman
Annalisa Buffa
Weinan E
Irene Fonseca
Isabelle Gallagher
Martin Hairer
Mike Hopkins
Meena Mahajan
Akshay Venkatesh
Anna Wienhard
Geordie Williamson

The ICM Structure Committee is encouraged to interact with the mathematical community worldwide.

Program Committee for 2026

The IMU Executive Committee appointed the ICM 2026 Program Committee (PC) at its meeting in March 2023. The chair of the PC is appointed by the IMU President. The PC will decide all speakers at ICM 2026. With the exception of the chair, membership in the PC is not normally made public until the Opening Ceremony of the ICM. The reason for this secrecy has been to protect the members of the committee from personal or political pressure from outside. Invitations to lecture at the International Congresses carry such high prestige that individuals or groups have always made efforts to influence the decisions of the committee.

The roles the Program Committee and the Organizing Committee play are described in the PC/OC Guidelines.

Chair of the ICM 2026 Program Committee:

Claire Voisin
CNRS, Institut de Mathématiques de Jussieu-Paris Rive Gauche
