NSF
The NSF Directorate for Education and Human Resources (EHR) invites grantees with active awards in specific programs to request supplemental funds to support a new postdoctoral researcher for up to two years or a continuing postdoctoral researcher for one year. Supplemental funding may be used only for support of a postdoctoral researcher to engage in mentored STEM research or STEM education research and development on active EHR awards. Please see the link for the list of eligible award programs.
