The American Federation for Aging Research (AFAR) has announced the distinguished recipients of its 2025 Grants for Junior Faculty, a prestigious award designed to propel early-career investigators toward groundbreaking achievements in the biology of aging. With each grant offering up to $150,000 over a one- to two-year period, this program aims to catalyze the careers of MD and PhD scientists, providing critical funding during a phase when securing research support is notoriously challenging. Through a rigorous selection process supported by leading philanthropic organizations, these emerging scholars are embarking on innovative research projects that could reshape our understanding of aging mechanisms.
This year’s cohort of awardees embodies a diverse range of scientific inquiries, exemplifying the multifaceted approach required to decipher the complex biological and molecular processes underlying aging. Their investigations extend from cellular metabolism and immune regulation to neurobiology and regenerative medicine, reflecting AFAR’s commitment to supporting high-impact research across the full spectrum of aging biology.
One highlighted recipient, Dr. Jacob Brown from Florida State University, is exploring the therapeutic potential of oxylipins in ameliorating muscle atrophy induced by disuse during aging. Oxylipins are lipid-derived signaling molecules implicated in inflammation and tissue repair. Dr. Brown’s work seeks to determine whether modulating these pathways might enhance recovery from muscle deterioration, a significant contributor to frailty in elderly populations. This could pave the way for novel interventions targeting muscle resilience in aging individuals.
At Harvard Medical School, Dr. Ang Cui is delving into the intricacies of cytokine signaling and its influence on hematopoietic stem cell (HSC) fate decisions with age. Hematopoietic stem cells are responsible for maintaining blood cell populations, but their function declines as we age, contributing to immunosenescence and heightened disease susceptibility. Dr. Cui’s project aims to decode how cytokine milieus direct HSC differentiation and renewal, potentially uncovering molecular targets to rejuvenate aged immune systems.
Another promising investigation by Dr. Madison Doolittle at the University of Connecticut Health Center focuses on the phenomenon of premature aging and persistent cellular senescence following tissue injury resolution. Senescent cells—cells that cease dividing but remain metabolically active—accumulate with age and contribute to chronic inflammation and tissue dysfunction. Dr. Doolittle’s research attempts to discern how these residual senescent cells after injury might accelerate aging processes, providing insights crucial for developing senolytic therapies that selectively clear harmful senescent cells.
Neuroimmunology is represented by Dr. Sija He from the University of Texas Health San Antonio, who is investigating brain innate immunity’s role in regulating systemic aging. The central nervous system’s immune environment profoundly influences peripheral organ function and systemic homeostasis. Dr. He’s research may elucidate mechanisms by which neuroimmune interactions impact aging trajectories, potentially informing novel interventions for age-associated neurological and systemic disorders.
At the University of California Riverside, Dr. Huimin Zhang is advancing knowledge on T cell aging, specifically looking at the epigenetic regulation mediated by the transcription factor HELIOS and its impact on follicular helper T (TFH) cell differentiation. TFH cells are critical for adaptive immunity and vaccine responses, which wane with age. Understanding HELIOS’s role could reveal epigenetic manipulation strategies to bolster immune competence in older adults.
Dr. Meng Zhang at Scripps Research is pioneering the use of spatial multi-omics—the combined analysis of spatially resolved transcriptomics, proteomics, and metabolomics—to unravel neuro-immune crosstalk. His work captures the dynamic molecular dialogues within aging tissues, aiming to identify key signaling networks that drive age-related functional decline. This integrative approach promises a comprehensive mapping of aging biology at unprecedented resolution.
AFAR’s Grants for Junior Faculty are not only a source of financial backing but also a recognition of scientific promise at a turning point in researchers’ careers. Stephanie Lederman, EdM, Executive Director of AFAR, emphasizes that this grant program is “a core grant program since AFAR’s inception,” signifying its foundational role in nurturing talent that has continually pushed the frontier of aging research. These grants serve as essential catalysts enabling scientists to generate preliminary data, publish influential findings, and secure future funding.
The support system behind these grants is robust, with backing from philanthropic foundations such as the Marion Esser Kaufmann Foundation and the Hearst Foundations providing targeted underwriting. Additionally, the AFAR Board of Directors, along with numerous anonymous donors and charitable trusts, contribute to a diversified funding portfolio ensuring program sustainability. This collaborative funding ecosystem enables a high level of competitive support that sustains scientific innovation.
For over four decades, AFAR has been at the forefront of biomedical aging research, distributing over $225 million to more than 4,500 investigators across premier institutions. The organization’s strategic role transcends grantmaking; AFAR also coordinates interdisciplinary research networks and public-private partnerships, fostering a collaborative environment that accelerates translational breakthroughs. In 2025 alone, AFAR anticipates allocating over $12 million in funding to nearly 80 investigators, reflecting sustained commitment to combating age-related diseases and improving healthspan.
The scientific insights emerging from AFAR-supported projects increasingly reveal the plasticity of aging processes at the cellular and molecular levels. By modifying fundamental pathways such as inflammation, epigenetic regulation, and stem cell function, researchers are demonstrating that aging is not a fixed destiny but a malleable biological state. This paradigm shift lays the groundwork for therapies that could delay multiple chronic diseases simultaneously, extending both lifespan and quality of life.
AFAR’s portfolio is driving a new era in aging research, where innovative methodologies like spatial multi-omics, advanced immunophenotyping, and targeted epigenetic interventions converge. The junior faculty currently funded through this program embody the next generation of thought leaders poised to revolutionize geroscience. Their work holds the promise of transforming clinical paradigms by enabling early interventions that preserve tissue function, enhance immune resilience, and mitigate degenerative processes.
Ultimately, these grants represent more than financial support; they symbolize a strategic investment in the future of aging science. By empowering early-career scientists to pursue high-risk, high-reward studies, AFAR is catalyzing knowledge that will unlock therapeutic potentials and shape public health trajectories. As our global population ages, this pioneering research is vital to ensuring that longer lives are paired with sustained health and vitality.
