The reliability theory of aging is an attempt to apply the principles of reliability theory to create a mathematical model of aging. The theory was published in Russian by Leonid A. Gavrilov and Natalia S. Gavrilova as Biologiia prodolzhitelʹnosti zhizni in 1986, and in English translation as The Biology of Life Span: A Quantitative Approach in 1991.[1][2]
One of the models suggested in the book is based on an analogy with the reliability theory. The underlying hypothesis is based on the premise that humans are born in a highly defective state. This is then made worse by environmental and mutational damage; redundancy allows the organism to survive for a while.[3]
The book criticized a number of hypotheses known at the time, discussed drawbacks of the hypotheses put forth by the authors themselves, and concluded that regardless the suggested mathematical models, the underlying biological mechanisms remain unknown.[4]

Leonid A. Gavrilov is a Russian-born American scientist. He is a research associate at the Center on Aging of the National Opinion Research Center in Chicago, in the United States. He specializes in the mathematical modeling of aging and mortality, biodemography and the genetics of aging and longevity. He and his wife Natalia S. Gavrilova have proposed a reliability theory of aging. Gavrilov has written two books, several chapters and numerous scientific papers.[citation needed] He is currently a Senior Research Associate at the University of Chicago.
Biography
Gavrilov has an MSc in chemistry (1976) and a PhD in genetics (1980), both from Moscow State University. His book The Biology of Life Span: A Quantitative Approach was published in Russian in 1986 and in English translation in 1991.[5][6] In 1998 he and his wife emigrated to the United States, where he received a grant from the National Institute on Aging to study the effects of parental age on lifespan. He taught a course on "biodemography of human mortality and longevity" at the University of Chicago.[5]
Gavrilov is an associate editor of Experimental Gerontology and Theoretical Biology and Medical Modelling, and an editorial board member of Rejuvenation Research, Advanced Science Letters and The Scientific World Journal. He is a consultant for the National Research Council and the National Institute on Aging,[5] and a fellow of the Gerontological Society of America.
