Research Supplements at NIEHS

Office Worker

Principal investigators holding NIEHS research grants may request supplemental funds for two purposes:

  • to meet unforeseen costs not included in the previous competitive or non-competitive application, or
  • to provide funding opportunities for special populations to enter or re-enter biomedical research.

Principal investigators at domestic institutions with an active NIEHS research grant, and with a reasonable period of research support (usually 2 years or more) remaining at the time of the supplemental award, are eligible to submit a request to NIEHS for an administrative supplement to the grant.

General Administrative Supplements

Supplemental funds can be requested for emergency or other unforeseen situations which result in unforeseen costs, such as natural or manmade disasters that damage the PI's lab or other research resources, failure of essential equipment, or unexpected or increased costs of recruiting subjects or performing laboratory analyses. Grantees may also request funds to update equipment or methodologies that have become out of date. The grantee must show that the new methodology will significantly enhance the quality of the data. Finally, under some circumstance, grantees may request funds to follow up on unanticipated results or to enhance components of their research that have in unexpectedly productive. However, these enhancements must be within the scope of research proposed and reviewed in the parent grant. Grantees should contact their Program Officer about this type of supplement.

Supplement Programs for Special Populations

Supplement programs are used to offer laboratory experience to a wide array of individuals including high school students, undergraduate students in health-related sciences, underrepresented minorities, persons with disabilities, scientists re-entering the work force after taking time off for family responsibilities, etc. Individuals may receive support under these programs on only one grant at any time, but may be supported by more than one grant during their research careers.

In general, Review Meetings are typically held 2 weeks after Council. Submissions are normally due 6 weeks before Council.

*Specific dates will be posted for each round.
