Inside American University's largest research partnership: Johns Hopkins University
Behind American University's research output sits a defining relationship: 134 co-authored works with Johns Hopkins University (United States) in the five years to 2025, the university's single largest collaboration.
It anchors an unusually connected research base: 747 collaborating institutions across 70 countries, producing 6,745 joint works over the window, with international co-authors on 23% of output.
The collaborative work travels: its field-weighted citation impact stands at 3.44, 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.
