Inside Swansea University's largest research partnership: Cardiff University

Behind Swansea University's research output sits a defining relationship: 811 co-authored works with Cardiff University (United Kingdom) in the five years to 2025, the university's single largest collaboration.

It anchors an unusually connected research base: 1,032 collaborating institutions across 78 countries, producing 16,371 joint works over the window, with international co-authors on 47% of output.

The collaborative work travels: its field-weighted citation impact stands at 3.67, where the world average is 1.0.
