Ronald Kohanski, Ph.D.

Deputy Director, Division of Aging Biology
National Institute on Aging (NIA), NIH


Ronald A. Kohanski, PhD. is the Deputy Director of the Division of Aging Biology at the National Institute on Aging, NIH. Trained as a biochemist, he obtained a Ph.D. in Biochemistry with Robert L. Heinrikson at the University of Chicago in 1981. After a postdoctoral fellowship with M. Daniel Lane at the Johns Hopkins University, he held faculty positions at the Mount Sinai School of Medicine and Johns Hopkins University. His fields of research included enzymology and developmental biology. Dr. Kohanski joined the Division of Aging Biology, NIA in 2005 as a Program Officer, and became Division Deputy Director in 2007. Dr. Kohanski promotes efforts to include aging as an experimental parameter in the study of disease, to identify biomarkers of physiological aging and to rigorously examine the heterogeneity of aging. Since 2007, he has sought to expand the use of systems biology in the study of aging.

Dr. Kohanski is a co-founder and co-leader of the trans-NIH Geroscience Interest Group with Dr. Felipe Sierra. Together they are editors of “Advances in Geroscience” (Springer International Publishing, 2016) and co-authors on several publications about geroscience. The group seeks to promote research on the “geroscience hypothesis” which states that slowing the rate of aging will delay the initiation or diminish the severity of adult-onset diseases and loss-of-resilience.
