About this agency
The National Institute of Environmental Health Sciences (NIEHS), a sub-agency of the National Institutes of Health within the Department of Health and Human Services, acquires research infrastructure, scientific software, genomic analysis tools, and technical expertise to support environmental health and translational toxicology research.
NIEHS operates a large contract portfolio spanning 19,432 awards since 1994, with combined potential value of $11.97 billion and $7.09 billion obligated to date. Recent contract activity has declined: 525 awards in 2022, 358 in 2023, 349 in 2024, 207 in 2025, and 171 year-to-date in 2026. The most recently recorded award date is 2026-10-23. Among prime contractors in the last five years, award concentration is fragmented at 18 percent of recent awards held by the top five, dominated by Illumina, Inc. (110 awards, $8.8 million combined potential value), Mdb, Inc. (63 awards, $17.7 million), and Fisher Scientific Company L.L.C. (48 awards, $1.3 million). By potential value over the same window, concentration is highly fragmented at only 1 percent held by the top five; Social & Scientific Systems, Inc. leads by value with $39.6 million across 15 awards, followed by Mdb, Inc. at $17.7 million and Sikich Federal Inc. at $9 million. The vast majority of contracts are unrestricted open competition: 17,882 awards (92 percent) carry no set-aside designation, with small-business set-asides accounting for 7 percent of awards and all other socioeconomic designations combined under 1 percent.
NIEHS also funds grants across 3,897 awards since 1975, obligating $10.41 billion in federal dollars ($11.02 billion including non-federal cost share). Grant activity totaled 343 awards in 2024, 230 in 2025, and 214 so far in 2026; award dates recorded in 2027 and 2030 reflect multi-year commitments. Grant recipients are highly fragmented: the top five by award count hold only 11 percent of recent awards, led by Columbia University (38 awards, $62.7 million federal dollars), Emory University (34 awards, $87.8 million), and Icahn School of Medicine at Mount Sinai (32 awards, $65.8 million). By federal dollars, concentration is also highly fragmented at 3 percent held by the top five. Grant funding is predominantly Project Grants (3,756 awards, 96 percent) with a small share of Cooperative Agreements (141 awards, 4 percent).
Recent contract opportunities focus on specialized genomics and bioinformatics infrastructure: solicitations include Illumina DRAGEN throughput licenses and servers for the NHGRI Undiagnosed Diseases Program (due September 14, 2026), MIMICS Materialise 3D image reconstruction software for the BETA Center (due September 14, 2026), and a pre-solicitation for scientific evidence evaluation and knowledge integration support for the Division of Translational Toxicology through systematic reviews, evidence synthesis, and technical consulting (due September 3, 2026).
