Leibniz Institute on Aging - Fritz Lipmann Institute (FLI)
We conduct research on the biology of aging at the molecular, cellular, and systems levels.
Aging Research at FLI
To study the biological foundations of aging — from molecules to entire organisms - we conduct multi-disciplinary research, combining evolutionary approaches, diverse model systems, and cutting-edge omics technologies.
Institute's Research Infrastructure
... combines state-of-the-art core facilities, core services, animal facilities, and specialized units into a powerful network for excellent research.
Research in Dialogue
Whether scientific conferences, lectures, or events for students and teachers, as well as our series Science & Society, or the Long Night of Sciences, and MINT Festival for the general public – we offer insights into our work in aging research.

PhD Positions - call for application
The Leibniz Graduate School on Aging (LGSA) is a joint program of the Leibniz Institute on Aging – Fritz Lipmann Institute (FLI) and the Friedrich Schiller University (FSU) in Jena. The School calls for applications for PhD positions.
Storing defective energy: How the aging brain remains efficient
An international research team led by the Leibniz Institute on Aging – Fritz Lipmann Institute (FLI) in Jena, Germany, and the University of Tennessee Health Science Center, Memphis, USA, has uncovered new insights into healthy brain aging. Researchers found that aging leads to the accumulation of defective energy molecules in the brains of aged mice, like humans, and identified the responsible genetic sequence. Importantly, no evidence was found that this accumulation would impair brain function, highlighting that age-related brain changes are not necessarily harmful.
Aging research in the spotlight: A look back, the status quo, and a vision for the future
Scientists around the world are trying to solve the “mystery of aging” and understand what “aging” means—biologically, clinically, and socially. In the newly published perspective article “Past, present, and future perspectives on the science of aging” in the Nature Aging journal, more than 50 researchers from various disciplines review the achievements of aging research so far and draw a vision for the future. Among those contributing to the article is Dr. Handan Melike Dönertaş from the Leibniz Institute on Aging – Fritz Lipmann Institute (FLI) in Jena, Germany. With her research group “AI in Microbiome and Aging Research”, she is providing important impetus for the systems biology of aging.
Why do muscles regenerate slower in old age?
A study now published in the journal "Science" shows how muscle stem cells protect themselves from loss in old age: as we age, muscles lose their ability to regenerate quickly, due to increased production of the protein NDRG1 in muscle stem cells. Prof. Dr. Julia von Maltzahn from the BTU Cottbus-Senftenberg, who has spent many years researching muscle regeneration during aging as a group leader at the Leibniz Institute on Aging – Fritz Lipmann Institute (FLI), has published a commentary on this article, as these new findings will change the way we look at changes in stem cells during aging.
