Connected: The Surprising Power of Our Social Networks and How They Shape Our Lives

Nicholas A. Christakis, MD, PhD, MPH, is a social scientist and physician who conducts research on social factors that affect health, health care, and longevity. He directs the Human Nature Lab at Yale University, and is the Co-Director of the Yale Institute for Network Science. He is the Sol Goldman Family Professor of Social and Natural Science at Yale University.

 

Dr. Christakis' lab is currently focused on the relationship between social networks and health. People are inter-connected, and so their health is inter-connected. This research engages two types of phenomena: the social, mathematical, and biological rules governing how social networks form ("connection") and the biological and social implications of how they operate to influence thoughts, feelings, and behaviors ("contagion"). Other ongoing investigations in the lab consider the biodemographic determinants of longevity and the genetic bases for human behaviors.

 

Along with his long-time collaborator, James Fowler, Dr. Christakis has authored a general-audience book on social networks: Connected: The Surprising Power of Our Social Networks and How They Shape Our Lives, which has been translated into nearly twenty foreign languages.
