Interdisciplinary Studies of Aging Section

Tamara B. Harris, MD, MS, Chief

The role of the Interdisciplinary Studies of Aging Section is to integrate molecular and genetic epidemiology with interdisciplinary studies of functional outcomes, disease endpoints and mortality in older persons. This includes identification of novel risk factors and design of studies involving biomarkers, selected polymorphisms and exploration of gene/environment interactions. The Section has been particularly active in devising methods to integrate promising molecular or imaging techniques in ways that begin to explore the physiology underlying epidemiologic associations including adaptaton of imaging protocols to epidemiologic studies.
