Since the 1990s, Christakis has worked as a preschool teacher, college administrator and instructor, educational consultant, and writer and journalist. From 2009-2013, Christakis was appointed Co-Master, together with her husband, the scientist Nicholas Christakis, of Pforzheimer House at Harvard College. In 2013, Christakis moved to Yale University, where she was appointed Lecturer in Early Childhood Education at the Zigler Center in Child Development and Social Policy at the Yale Child Study Center. At Yale, she has taught undergraduate courses in child policy, early childhood education, and child development. She was appointed Associate Master of Silliman College, one of Yale’s 12 residential colleges, in the spring of 2015, a post she held until June, 2016. Christakis has written on the developmental needs of children, young adults, and families, and on popular culture and other topics, for many venues, including The Atlantic, CNN.com, The Washington Post, The Huffington Post, the Financial Times, and The Boston Globe. She wrote a TIME.com Ideas column for two years. She has written in the defense of the rights of minors and criticized the increasing bureaucratization of American schooling. Her article in The Atlantic in early 2016, “The New Preschool Is Crushing Kids,” was described in Slate as having an “explosive” effect on the education world. Her book, The Importance of Being Little: What Preschoolers Really Need From Grownups was published by Viking Penguin in February 2016, and it debuted on the New York Times Hardcover Nonfiction Bestseller List ofFebruary 28, 2016 at number 19. Science described the book as "superbly written" and "supported by a rich scientific literature." In October 2019, she joined the National Advisory Board of Defending the Early Years. Christakis has spoken twice at the Aspen Institute Ideas Festival.
Support of free expression
In October, 2015, in her capacity as Associate Master, Christakis wrote an e-mail to the undergraduates at Silliman College on the role of free expression in universities. This email was in response to a directive from the Intercultural Affairs Committee at Yale that provided guidelines regarding Halloween costumes. In her email, she argued that, from a developmental perspective, students might wish to consider whether administrators should provide guidance to college students regarding Halloween attire or whether students should be allowed to "dress themselves." According to The Atlantic, "Her message was a model of relevant, thoughtful, civil engagement." But the message played a role in protests at Yale about several issues, and it received national attention. This incident prompted a number of social critics to comment on possible generational changes. Christakis eventually decided to no longer teach at Yale, and, on the anniversary of the events, she described the difficult circumstances she had faced, expressing concern that a "culture of protection may ultimately harm those it purports to protect." While in a similar post at Harvard in 2012, Christakis was also involved in the defense of free expression. She came to the defense of minority students who were using satire to criticize the final clubs at that institution, arguing that policing free expression on campus "denies students the opportunity to learn to think for themselves." In another column that same year, she came to the defense of a high school student wearing a T-shirt supporting gay rights.
