Sabino Kornrich is a sociologist who studies inequality, gender, and the family in the United States and across developed countries. He is particularly interested in examining competing understandings of inequality and the family: whether these domains function according to economic or social rules, and how and they change over time.

His research on changing parental investments in children has been published in Demography and featured in the New York Times, the Economist, and the Atlantic. His other research on gender and inequality has been published in the American Sociological Review and the American Journal of Sociology. His newest projects examine how the rise of online dating has shaped matching in marriage and examine historical changes in the age at first marriage.
