Inside University of Tartu's largest research partnership: Charles University
Behind University of Tartu's research output sits a defining relationship: 975 co-authored works with Charles University (Czechia) in the five years to 2025, the university's single largest collaboration.
It anchors an unusually connected research base: 1,055 collaborating institutions across 75 countries, producing 17,322 joint works over the window, with international co-authors on 60% of output.
The collaborative work travels: its field-weighted citation impact stands at 3.19, 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.
