About Joshua Mitteldorf, Ph.D.

Joshua Mitteldorf studies aging from an evolutionary perspective, using computer modeling and statistics. His book, with Dorion Sagan, Cracking the Aging Code, (2016) from Flatiorn/Macmillan lays out evidence that aging has evolved as a compromise between fitness of the individual and stability of the ecosystem. He has gone on to explore the surprising implications for medical research and anti-aging practice. He comments on news in the science of aging at and offers a personal anti-aging program at His political writings are featured at, while his poetry, essays and aphorisms appear at Mitteldorf’s current project is a large-scale study using an epigenetic clock to evaluate a broad range of anti-aging interventions in current use, and their mutual interactions. The study of aging is a second career for Mitteldorf. His original training was in astrophysics.
