Nicholas A. Christakis, MD, PhD, MPH, is an internist and social scientist who conducts research on social factors that affect health, health care, and longevity.
He is Professor of Medical Sociology in the Department of Health Care Policy at Harvard Medical School; Professor of Medicine in the Department of Medicine at Harvard Medical School; Professor of Sociology in the Department of Sociology in the Harvard Faculty of Arts and Sciences; and an Attending Physician (with an emphasis on palliative medicine) in the Department of Medicine at the Mt. Auburn Hospital in Cambridge, Massachusetts. He is the Master of Pforzheimer House in Harvard College.
Dr. Christakis' current work is principally concerned with health and social networks. This work takes seriously the contention that because people are inter-connected, their health is inter-connected. This work explores two aspects of social networks: the process by which they form ("connection") and the way they operate to influence behaviour ("contagion"). Related work examines the health benefits of marriage and the consequences of spousal illness and widowhood. Other ongoing investigations consider the effects of neighbourhoods on people's health, the biodemographic determinants of longevity, and the genetic bases for human behaviours. His past work has examined the accuracy and role of prognosis in medicine and ways of improving end-of-life care.
