Cagliari is the largest city of the island of Sardinia. This location provides an inspiring setting for scientific exchange at the crossroads of the Mediterranean. Sardinia’s long history of population continuity, episodes of contact and isolation, and rich cultural and linguistic heritage make it a particularly meaningful place to reflect on questions of human history and diversity. The city’s compact historic center and coastal landscape with beautiful beaches offer a welcoming space for focused discussion, collaboration, and informal interaction beyond the meeting sessions. The end of September is a perfect season to enjoy the warm climate of the island, with swims and hikes.
