Summary
This action funds an NSF Postdoctoral Research Fellowship in Biology for FY 2025. The fellowship supports research and training of the fellow that will contribute to biology in innovative ways. Despite the numerous known associations between the human gut microbiome and health or disease, progress towards establishing what causes these outcomes has been slow.
