Invited researchers

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.
Associated professorships 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.
