Inside Technische Universität Braunschweig's largest research partnership: Leibniz University Hannover

Behind Technische Universität Braunschweig's research output sits a defining relationship: 969 co-authored works with Leibniz University Hannover (Germany) in the five years to 2025, the university's single largest collaboration.

It anchors an unusually connected research base: 909 collaborating institutions across 76 countries, producing 15,117 joint works over the window, with international co-authors on 34% of output.

The collaborative work travels: its field-weighted citation impact stands at 2.11, 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.
