Inside Boston University's largest research partnership: Harvard University
Behind Boston University's research output sits a defining relationship: 6,700 co-authored works with Harvard University (United States) in the five years to 2025, the university's single largest collaboration.
It anchors an unusually connected research base: 1,129 collaborating institutions across 80 countries, producing 45,462 joint works over the window, with international co-authors on 32% of output.
The collaborative work travels: its field-weighted citation impact stands at 3.58, 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.
