Siegfried Hekimi (born 5 September 1956) is a Swiss former professional racing cyclist and a professor in the Biology Department of McGill University, specializing in the study of aging.
After his cycling career, Hekimi obtained a Ph.D. in neurobiology at the University of Geneva.
He became a full professor in 2004 at McGill University and his research has extended to include mouse models of aging and of age-dependent diseases.
[4][5] Hekimi uses nematode Caenorhabditis elegans for translational studies in the biology of aging; in particular the genetic, cellular, and molecular mechanisms of the organisms.
He believes the findings will translate into higher organisms like mice and humans.
