Buck Institute For Research On Aging

Buck Institute For Research On Aging, a non-profit research organization headquartered in Novato, California, receives federal funding as a prime recipient of NIH grants and as a consortia member on a Defense Advanced Research Projects Agency Other Transaction Agreement, conducting basic and translational biogerontology research focused on aging mechanisms, age-related diseases, and interventions targeting healthspan extension.

The institute operates almost entirely within the NIH grant ecosystem, with 184 of 212 recent awards (87%) as a prime recipient and the remainder as a sub-recipient on university-led cooperative agreements and collaborative grants. The National Institute on Aging (NIA) dominates its customer concentration, accounting for 70 awards across the recent portfolio, while the broader National Institutes of Health ecosystem (including the National Institute of Diabetes and Digestive and Kidney Diseases, the Office of the Director, the National Institute of Neurological Disorders and Stroke, and the National Institute of Child Health and Human Development) covers 83% of all awards. Buck Institute's only non-NIH contract vehicle is a DARPA Other Transaction IDV with a $8 million ceiling awarded June 15, 2025, under the Simulating Microbial System (SMS) program, reflecting the institute's recent expansion into defense-funded research modeling microbial system dynamics in aging contexts.

The institute's research portfolio centers on cellular and molecular mechanisms of aging hallmarks — cellular senescence, mitochondrial dysfunction, loss of proteostasis, and lysosomal biology — using Drosophila melanogaster, yeast, mouse models, human-induced pluripotent stem cells, and human tissue cohorts. Representative prime grant awards include a $821,486 NIA Aging Research (CFDA 93.866) grant awarded August 15, 2026, investigating diet-reproduction interactions in ovarian aging and systemic healthspan through human population datasets and fruit fly mechanistic studies; a $809,486 NIA Aging Research grant awarded February 1, 2026, examining the role of OXR1 and retromer proteins in brain aging and Alzheimer's disease using dietary restriction as an intervention; a $533,500 NIA award dated July 15, 2026, investigating autonomic innervation's role in muscle stem cell aging and sarcopenia; and a $194,000 National Institute of Child Health and Human Development grant dated September 1, 2026, studying ovarian aging through three-dimensional lymphatic network structure and function. The institute also holds a $7.994 million DARPA SMS OT IDV (award date June 15, 2025) supporting research in spatial molecular imaging using mass spectrometry platforms, proteomics, metabolomics, and lipidomics across human and animal tissue models.

Buck Institute brings direct capability in state-of-the-art spatial molecular imaging and mass spectrometry profiling, evidenced by its recent NIH-funded acquisition of a Bruker timsTOF Flex MALDI-2 system for spatial imaging of proteins, lipids, and metabolites at five to ten micrometer resolution, and active research programs in spatial proteomics of osteoarthritis, senescence mapping in human organs, and multi-omic analysis of aging tissues. The institute operates multiple research cores — mass spectrometry, AI and data science, and bioenergetics — supporting its own investigators and collaborative partner institutions. It also houses the Geroscience Education and Training (GET) Network pilot program and hosts the annual Reproductive Aging Conference, positioning it as a training and community hub within geroscience.

Sub-recipient work is predominantly collaborative and anchored by university prime awardees. Buck investigators perform sub-contracted mass spectrometry-based proteomics, metabolomics, spatial imaging, and immunological profiling on cooperative grants led by Stanford University, the University of Washington, Johns Hopkins University, the University of Michigan, UCSF, the University of Pittsburgh, Brown University, and others. Recent sub-awards (dated 2024–2026) include contributions to Stanford's longitudinal immune monitoring consortium, Johns Hopkins' senescence mapping in human organs, and multiple University of Michigan and UCSF studies of bone quality, osteocyte biology, and musculoskeletal aging.

Activity has remained relatively stable at 6 to 12 awards per year across 2022–2026, with 17 awards facing completion in the next twenty-four months and therefore subject to recompete. The institute's federal footprint reflects a specialist positioning in geroscience and translational aging research rather than broad federal contracting exposure; growth trajectory is shallow and customer concentration is extreme — the NIA accounts for roughly one-third of all awards by count and the entire NIH system accounts for the remaining substantial majority.
