National Institute of Environmental Health Sciences (NIEHS)

Mission Statement

The NIEHS Mission is to research how the environment affects biological systems across the lifespan and to translate this knowledge to reduce disease and promote human health.


Interest Areas

General Topics

The NIEHS supports research, training and career development programs on the biological response and human health impacts of exposures from environmental sources (see NIEHS Strategic Plan 2025-2029).  

  • Environmental exposures include chemical, physical, and biologically derived (non-pathogenic) factors that humans can be exposed to via inhalation, ingestion, or ocular/dermal contact, individually or as mixtures.
  • Research supported includes:
    • the development of technologies to assess human environmental exposures and biological impacts of exposure;
    • mechanistic understanding of exposures on biological systems including the use of environmentally derived analytes as probes of fundamental biological mechanisms;
    • epidemiological studies of the health effects of environmental exposures including the interactions between environmental and genetic factors;
    • community engaged research; and
    • the development of strategies to reduce the burden of exposure and mitigate the impacts of exposures to improve human health at the individual and population levels.
  • Research  must be anchored in human health relevant outcomes
    • Outcomes may be at the molecular, cellular, organ, system, organism or population level.
    • Use of computation and non-human models is allowed, provided relevance to human health is justified
  • Through the Superfund Research Program, NIEHS also supports research on environmental science and engineering, including the development and validation of remediation technologies and studies of the environmental fate and transport of chemicals.  This work can be removed from a direct relevance on human health and biomedical research efforts.
  • Through the Worker Training Program, NIEHS supports the training of workers engaged in activities related to hazardous or radioactive materials and waste generation, removal, containment, transportation, and emergency response.  This includes the development of training curricula and materials.

Conferences and Meetings
In addition to our Conferences and Meetings overview, consider the following NIEHS-specific information.
Conferences and Meetings Interest Areas:

The NIEHS Conference Grant Program supports investigator-initiated scientific meetings —such as conferences, workshops, symposia, and seminars— that directly advance the institute’s mission, particularly research on how environmental factors and gene–environment interactions influence disease or dysfunction. Relevant topics include environmental toxicology, chemical exposure, mechanistic toxicology, environmental epidemiology, exposure science, detection of hazardous substances, and scientific methods to reduce environmental hazards. Support is available for events of all sizes. For larger conferences, NIEHS prioritizes multidisciplinary or interdisciplinary events that foster collaboration among researchers. Applications are encouraged to include graduate students, postdoctoral fellows, junior investigators, and community members with funding allowed for their participation. 

The NIEHS Superfund Research Program also supports meetings relevant to their interest areas.

Conferences and Meetings Budget Considerations:

NIEHS limits conference grant awards to no more than $25,000 in direct costs per year for new (had no previous NIEHS support) and $50,000 in direct costs per year for returning (had previous NIEHS support) conferences. Typical support is less than the outlined limits. NIEHS will consider providing co-funding for conference applications administered by other ICOs (usually less than $10,000).

Conferences and Meetings Key Date Considerations:

NIEHS considers applications submitted to all conference standard due dates.

It is highly suggested that applicants reach out to the NIEHS Conference Grant Coordinator no later than 6 weeks prior to the receipt date with any questions.

Conferences and Meetings Project Period Considerations:

NIEHS considers requests for a single conference or a series up to 3 years.
