During federal fiscal year 2023, Indiana University School of Medicine investigators received over $243 million in National Institutes of Health research funding — bringing the school’s national NIH funding ranking to No. 13 among all public medical schools and No. 29 among all schools in the United States, according to the Blue Ridge Institute for Medical Research.

Blue Ridge is a nonprofit organization that annually ranks U.S. medical schools by NIH grants awarded each federal fiscal year. The NIH is the largest public funder of biomedical research in the world, and the 2023 federal fiscal year was Oct. 1, 2022, to Sept. 30, 2023.

Across the 27 centers and institutes that make up the NIH, the National Institute on Aging (NIA), the National Heart, Lung and Blood Institute (NHLBI) and the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) were the largest sources of NIH grant funding to IU School of Medicine researchers in 2023 — with nearly $71.8 million from the NIA, over $30.8 million from the NHLBI and nearly $25.5 million from the NIDDK.

The IU School of Medicine was also among the U.S. medical schools receiving the largest amounts of funding from the National Institute on Alcohol Abuse and Alcoholism (NIAAA), the NIA and the NIDDK — ranking No. 3 in NIAAA funding among all medical schools in the country, No. 6 in NIA funding and No. 20 in NIDDK funding.
