Marianne Cooper is a sociologist at the Clayman Institute for Gender Research at Stanford University. She was the lead researcher for Sheryl Sandberg’s book, Lean In: Women, Work, and the Will to Lead. In this role, she provided academic expertise to help explain concepts discussed in the book and was in charge of assimilating the body of research that was profiled in the book. She is an expert on gender, family life, work, and social inequality. She writes, speaks, and consults about these issues for media outlets, companies, and professional groups. Her forthcoming book, Cut Adrift: Families in Insecure Times, examines what keeps Americans up at night. Set against the backdrop of rising economic insecurity and rolled up safety nets, Cut Adrift explores how families forge security in an uncertain age. Through poignant case studies, her book reveals what families are concerned about, how they manage their anxiety, whose job it is to worry, and how social class shapes all of these dynamics, including what is even worth worrying about in the first place. Cut Adrift makes an important and original contribution to the national conversation about inequality and risk in American society. She received her Ph.D. in sociology from the University of California, Berkeley.
