FY2026 NIH awards · Principal investigators
Neurosurgery at CommonSpirit Health
Chicago, IL · Sum of member hospitals
- NIH names only the principal investigators on an award, so this page lists only them. The department is the award's: it is where ScienceDex counts the award, not a list of the department's members.
- NIH gives hospital awards no department code. Each counts under its contact PI's own department, from their PubMed affiliations, or under a department inferred from the award's topic when no affiliation names one. Each award below says which. How departments are assigned
- Awards at CommonSpirit Health's member hospitals under the department-ranking rules: awards with a department, R&D contracts left out. They match CommonSpirit Health's Neurosurgery row on the system page.
