He is a social and economic demographer working at the intersection between family processes (divorce, marriage and fertility) and child and economic outcomes (savings, labour supply and type) to understand social stratification. Much of his work is inherently interdisciplinary, cutting across research in demography, population economics, and sociology. His published research can be found in internationally prominent journals of all three disciplines, such as Annual Review of Sociology, Proceedings of National Academy of Science (PNAS), Demography, Journal of Human Resources, European Economic Review, among others.
