Adam L. Horowitz received his Ph.D. in Sociology from Stanford University in 2016. Horowitz’s scholarship examines how genetic technologies are changing the nature by which ethnoracial membership is evaluated. Horowitz’s dissertation research evaluated Jewish converts’ use of genetic ancestry testing (GAT) in conceptualizing authentic Jewishness. By drawing connections between converts’ use and how GAT has been adopted into global citizenship politics (i.e., as an evaluable metric used for determining access to national and/or tribal membership), Horowitz advances understanding of how genetic technology is altering the social dynamics of ethnoracial claims-making and, as it becomes encoded into enforceable policy, affecting legal and political rights. In new research, Horowitz is studying people who discover relatives of different races through GAT, examining how increasing use of genetic technology influences social perceptions of relatedness and of the extent to which ethnoracial difference is essential.
