Structure and Organization
The Peter Grünberg Institute consists of 14 scientific departments with complementary research interests and a support unit for the technical-scientific infrastructure. Each director of an institute division is appointed jointly with a university. The JARA institutes, which are operated jointly with RWTH Aachen University, play a special role. The institutes JCNS-2 in neutron research and ER-C-1 in electron microscopy continue to be closely associated with the Institute as former PGI divisions and are represented on the Board of Directors as guests.

A key element of the PGI’s strategic concept is JARA – Jülich Aachen Research Alliance, the alliance between Forschungszentrum Jülich and RWTH Aachen University. This is achieved in particular through the JARA section Fundamentals of Future Information Technology (JARA-FIT). Within the framework of JARA, PGI has been extended by the formation of two new JARA Institutes: Green Information Technology (PGI-10) and Quantum Information (PGI-11).
The PGI shares a common Technical and Administrative Infrastructure with the Jülich Centre for Neutron Science (JCNS). The heads of the scientific departments form the Board of Directors. The Board of Directors manages the everyday business, draws up the research programme and determines PGI 's overarching strategy. At regular intervals, the board elects one of its members as the Managing Director.
