Inside Carnegie Mellon University's largest research partnership: University of Pittsburgh

Behind Carnegie Mellon University's research output sits a defining relationship: 1,662 co-authored works with University of Pittsburgh (United States) in the five years to 2025, the university's single largest collaboration.

It anchors an unusually connected research base: 1,057 collaborating institutions across 78 countries, producing 34,897 joint works over the window, with international co-authors on 31% of output.

The collaborative work travels: its field-weighted citation impact stands at 3.25, where the world average is 1.0.

The Research Collaboration Index, the first global account of how universities actually collaborate, publishes its first full edition on Tuesday 15 September at 09:00 UK.
