My research and teaching concern families and inequality, and public scholarship. I write about demographic trends, family structure, the division of labor, health disparities, as well as open science and related topics. My commentary on subjects ranging from race and gender inequality to parenting, poverty, and popular culture has appeared in outlets such as the New York Times, the Washington Post, the Atlantic, the Chronicle of Higher Education, and the New Republic. The results of my research have been widely reported in major media, and I often comment on new research or trends in the news.

My popular textbook, The Family: Diversity, Inequality, and Social Change, is now in its third edition. Since 2016, I have been the founding director of SocArXiv, an open archive for the social sciences, and an advocate for open science in the research community. I am active in efforts to reform the system of scholarly communication, and often speak on the topic of how scholars can productively engage with our many public audiences, to improve our work and deepen its impact.

I am working on a new book, titled Citizen Scholar, to be published by Columbia University Press. You can read essays as I develop the book here.
