In his words:
I am a social demographer who studies mating and dating, and the Internet's effect on society. I study family history and family law, especially as they relate to same-sex couples and their children. I am the author of many articles, and the book The Age of Independence: Interracial Unions, Same-Sex Unions, and the Changing American Family.
I am currently working on:
How Couples Meet and Stay Together, a longitudinal study of social life in the US, funded by the National Science Foundation. The first wave of the study was fielded in 2009. Public data, documentation, and further information is available at the Stanford Library's data distribution website. My first paper from this project, "Searching for a Mate: The Rise of the Internet as a Social Intermediary" was published in the August 2012 issue of the American Sociological Review. The How Couples Meet and Stay Together project has revolutionized our understanding of such topics as how couples meet, the role of technology and the role of family in personal relations, why couples stay together, and whether same-sex married couples stay together as long as heterosexual married couples do.
