The visitor programme represents the institute’s most important scientific activity. Each year, around 200 researchers are selected by the Scientific Council, after an application procedure. Drawn by the spontaneous and sometimes unexpected interactions that the Institute makes possible and encourages, visitors stay on average for 2.5 months.
Triennial chairs provide considerable flexibility for organising scientific activities, with the possibility of inviting collaborators and organising events, and chair holders can stay for longer periods at the Institute.

Gérard Ben Arous is a professor of mathematics at the Courant Institute of Mathematical Sciences at New York University and a specialist in probability theory and its applications.
The Israel Gelfand Chair was created in 2014 in honour of the great mathematician. It symbolises scientific excellence and the sharing of knowledge, two of the Institute’s fundamental values. Israel Gelfand himself came to IHES more than ten times to carry out his research. Since 2024, Israel Gelfand Chair is supported by Squarepoint Foundation. More information.
