His primary research interest revolves - broadly speaking - around intergenerational mobility and the inheritance of disadvantage, with a particular interest in the underlying mechanisms driving intergenerational associations. Richter’s dissertation involves a variety of topics that range from the role of prenatal health in shaping later life outcomes to the role of parental preferences in shaping parental investments. He started working towards his PhD in 2010 under the supervision of Markus Jäntti and Anders Björklund. Prior to this, Richter studied in Kiel, Germany, and Nottingham, UK.

William Schneider is a doctoral student concentrating in social policy and policy analysis at the Columbia University School of Social Work, where he is also a fellow at the Columbia Population Research Center. His advisor is Professor Jane Waldfogel. Mr. Schneider’s work is focused in the areas of child maltreatment, parenting, child development, and social policy. His research centers on the role of nonresident fathers in child development and the prevention of child abuse and neglect. Before coming to Columbia, he worked at the National Center for Children in Poverty at the Mailman School of Public Health at Columbia University and the Center for Research on Child Wellbeing at Princeton University. His dissertation focuses on the potential protective effects of involved parenting among low-income, nonresident, unmarried fathers. Specifically, it draws on data from the Fragile Families and Child Wellbeing Study to address the determinants and activities of involved parenting among these fathers, the prevalence of harsh parenting among different family formations, and the protective effect that fathers may provide against child abuse and neglect.
