Inside University of Wuppertal's largest research partnership: RWTH Aachen University
Behind University of Wuppertal's research output sits a defining relationship: 236 co-authored works with RWTH Aachen University (Germany) in the five years to 2025, the university's single largest collaboration.
It anchors an unusually connected research base: 818 collaborating institutions across 69 countries, producing 9,275 joint works over the window, with international co-authors on 40% of output.
The collaborative work travels: its field-weighted citation impact stands at 2.75, where the world average is 1.0.
The Research Collaboration Index, the first global account of how universities actually collaborate, published its first full edition on 15 September 2026. The full results are public.
Every figure derives from the open global research record and is checkable at source.
