Longevity Research Program

A collaboration of Washington University School of Medicine and Reinsurance Group of America, Incorporated (RGA), the Longer Life Foundation has as its mission: 

To fund and support the study of factors that either predict the mortality and morbidity of select populations or influence improvements in longevity, health, and wellness. 

The Longer Life Foundation

For more than 20 years, the Longer Life Foundation has awarded Pilot & Feasibility grant funding to investigators with novel ideas for advancing their research addressing topics related to the Foundation mission. We look to fund research studying determinants of long-term prognoses for common human ailments. Preference is given to clinical research that involves the potential for new discoveries rather than the implementation of existing therapeutic strategies. The Longer Life Foundation also funds studies that investigate methods to improve disease prognosis or prevent disease from occurring, thereby improving quality and quantity of life. However, these studies should involve diseases specifically posing a risk or are known to shorten life expectancy. The Foundation is interested in individual pilot and feasibility studies as well as pilot projects that are a component of larger or established studies, such as analyses of existing databases. 

Call for Applications: Developmental Research Awards 

The Longer Life Foundation announces the 2026 Call for Applications for WashU Medicine faculty for Pilot and Feasibility Research Projects addressing topics related to the Foundation’s mission. We are looking to fund research studying determinants of long-term outcomes for common human risk factors or conditions.
