About the Author

Aubrey de Grey, Ph.D., is chairman and chief science officer of the Methuselah Foundation. His major research interests are the role and causes of all forms of cellular and molecular damage in mammalian aging, and the design of interventions to reverse the age-related accumulation of such damage. He has published extensively on these and other areas of gerontology. He is also editor-in-chief of the high-impact journal "Rejuvenation Research, " the only peer-reviewed academic periodical focusing on intervention in aging. He has formulated a wide-ranging plan for the comprehensive and eventually indefinite postponement of age-related physical and mental decline, named SENS (Strategies for Engineered Negligible Senescence). He is the organizer of an ongoing series of conferences and workshops that focus on the key biomedical research relevant to SENS, and he also oversees the Methuselah Foundation's growing sponsorship of SENS research worldwide.
Michael Rae is Dr. de Grey's research assistant. He is the author of several scientific articles and commentaries in peer-reviewed scientific journals. He is a longtime member and onetime board member of the Calorie Restriction Society, a main contributor to the society's "How-to Guide," and a core scientific investigator with the society's Cohort Study, which seeks to document the feasibility of calorie restriction in humans and the potential human translatability of the anti-aging effects observed in laboratory organisms.
