Inside University of Southampton's largest research partnership: University of Oxford

Behind University of Southampton's research output sits a defining relationship: 2,144 co-authored works with University of Oxford (United Kingdom) in the five years to 2025, the university's single largest collaboration.

It anchors an unusually connected research base: 1,174 collaborating institutions across 81 countries, producing 43,409 joint works over the window, with international co-authors on 50% of output.

The collaborative work travels: its field-weighted citation impact stands at 3.56, where the world average is 1.0.
