Inside Cornell University's largest research partnership: Weill Cornell Medicine

Behind Cornell University's research output sits a defining relationship: 15,527 co-authored works with Weill Cornell Medicine (United States) in the five years to 2025, the university's single largest collaboration.

It anchors an unusually connected research base: 1,173 collaborating institutions across 81 countries, producing 109,128 joint works over the window, with international co-authors on 33% of output.

The collaborative work travels: its field-weighted citation impact stands at 3.3, where the world average is 1.0.
