Dr. Nicholas Christakis is the Sterling Professor of Social and Natural Science at Yale University and the Director of the Human Nature Lab. His research sits at the intersection of the social, biological, and computational sciences, exploring how our evolutionary biology and social network structures shape human behavior, health, and society. His groundbreaking work on "social contagion," demonstrates how everything from obesity and smoking to happiness and cooperative behavior spreads through human networks. Most recently, his work has focused on the emergence of "hybrid systems" of humans and machines, examining both the Burkean risks of how AI might degrade our interpersonal social graces and the technoprogressive potential of using "dumb bots" to optimize human coordination.
