The G. Harold & Leila Y. Mathers Foundation, established in 1983 in Santa Barbara, California, honors the philanthropic legacy of G. Harold Mathers and Leila Young Mathers. Their vision emphasized supporting basic medical research and scholarships. Over time, the Foundation has grown into a permanently endowed, independent philanthropic entity, dedicated to funding innovative basic science with translational promise.Headquartered in Rye Brook, New York, it is guided by a dedicated board of trustees.
1. High-Impact, High-Risk Funding
The Foundation targets bold, high-risk/high-reward basic science that’s usually not yet competitive for federal funding. The focus spans fields like immunology, microbiome research, structural biology, cellular physiology, cancer biology, genomics, infectious diseases, stem cell biology, and neuroscience. Clinical trials, drug discovery, COVID-19, plant biology, and environmental studies are explicitly excluded.
2. Generous and Programmatic Support
Grant size: Up to $600,000–$700,000 over three years, inclusive of a maximum 10% for indirect costs.
Eligible applicants: Independent PIs with their own, fully equipped labs at U.S.-based 501(c)(3) institutions.
Limited Submissions: Institutions can nominate up to three LOIs per cycle, with cycles in Spring (e.g., LOI due ~March 14, proposal due ~May 23, 2025) and Fall (e.g., LOI ~October 3, proposal ~December 12, 2025).
Strategic Funding Pathway: Acts as seed funding, helping investigators produce preliminary data essential for pursuing larger federal grants.
Selectivity & Prestige: Few recipients—at all career stages—receive such substantial, flexible support, making awardees stand out in the research community.
Encourages Innovation: Emphasizes novel, foundational discovery with translational potential, especially for projects not yet competitive for traditional grant mechanisms.
Cross-Institutional Impact: Recognized across institutions like Harvard, Stony Brook, USC, UCI, and Penn State, often generating internal competitions and broad institutional support.
Career Milestones: Securing a Mathers grant often signals a PI is ready to launch high-impact, independent research—making it a notable career inflection point.
