Inside Loma Linda University's largest research partnership: University of Southern California

Behind Loma Linda University's research output sits a defining relationship: 245 co-authored works with University of Southern California (United States) in the five years to 2025, the university's single largest collaboration.

It anchors an unusually connected research base: 763 collaborating institutions across 69 countries, producing 7,587 joint works over the window, with international co-authors on 24% of output.

The collaborative work travels: its field-weighted citation impact stands at 2.02, where the world average is 1.0.
