US National Institutes of Health
The NIH supports biomedical research. Their mission is to seek fundamental knowledge about the nature and behavior of living systems and to apply that knowledge to enhancing health, lengthening life, and reducing illness and disability. The NIH is made up of 27 institutes and centers, each with a specific research agenda, often focusing on particular diseases or body systems.
Not all of the NIH funding opportunities are open to researchers at foreign institutions. In general, researchers at Swiss institutions are eligible to apply as the main applicant for the following awards:
Some other awards, such as Program Project / Center Grants, may support Swiss participation so long as the main applicant is a US institution. The eligibility rules are specified in the calls (funding opportunity announcements).
