Alessandro Cellerino is a neurobiologist known for establishing the turquoise killifish (Nothobranchius furzeri) as a model organism for studying aging, due to its short lifespan and human-like aging traits. He earned his PhD from the Scuola Normale Superiore in Pisa and later became a group leader at the Leibniz Institute on Aging (FLI) in Jena, where he now leads the “Biology of Aging: Aging in Fast Motion” research group. His work focuses on brain aging, proteostasis, neuronal stem cells, and genetic regulation of lifespan. His team was the first to sequence the killifish genome and link specific gene expression patterns to aging, helping to advance aging research globally.
