He is full professor at the Faculty of Life Sciences[1] at Bar Ilan University[2] who studies the molecular mechanisms that determine the rate of aging.

In 1991, he began his undergraduate studies in life sciences at Bar Ilan University, which he graduated summa laude in 1994.

He demonstrated in a series of studies how the increase of SIRT1 activity, resulting from calorie restriction, supports healthy longevity.

In 2004 he joined the Faculty of Life Sciences, Bar-Ilan University, as the head of the Molecular Mechanisms of Aging’s lab.

These findings suggested that SIRT6 protein plays a key role in extending lifespan and prolonging healthy life through caloric restriction.

Furthermore, he found that SIRT6 protein protects against the development of the phenomenon of frailty that characterizes the elderly, mainly expressed mainly as fatigue and inactivity.

Through these series of studies, Cohen proved that SIRT6 is a key protein in metabolism and in determining healthy life expectancy.

In addition to these studies, Haim Cohen's research focused on other areas related to his understanding of the aging process.

In another big data study, he demonstrated that by genetic manipulations or diets it is possible to extend the maximum life expectancy of a person beyond what has been observed so far.
