The GIGA promotes the exchange and cooperation with leading scholars and institutions at the national and international level. It is a central hub in relevant research networks.

In cooperation with partners at home and abroad, the GIGA carries out joint research projects, organises events and releases publications. In the teaching and training of PhD students, the GIGA cooperates with various universities. In addition, outstanding researchers from all over the world arrive at the GIGA every year through the Visiting Fellowship Programme. In turn, GIGA researchers are involved worldwide with partner institutions and organisations.
