Agnes Tarnowski
Agnes Tarnowski was a doctoral researcher at the International Max Planck Research School on the Social and Political Constitution of the Economy (IMPRS-SPCE) at the Max Planck Institute for the Study of Societies since October 2018 (see her profile). She studied Social Sciences (B.Sc.) and Sociology and Empirical Social Research (M. Sc.) at the University of Cologne. In close connection to the SOCIALBOND project, her dissertation explored school principals’ sense making and meaning construction about a diverse student body by applying a nested mixed-method research design. Her successfully completed dissertation advanced our understanding of the obstacles and opportunities for integrating minority students into secondary schools in North Rhine-Westphalia.
Xinwei Xu
While pursuing a PhD in sociology at Cornell University, Xinwei Xu has been a visiting doctoral researcher in the SOCIALBOND project from October 2019 until 2021 on a DAAD scholarship. Her areas of interest include social networks, culture and cognition, and intergroup relations. Based on CILS4EU data, her dissertation research focused on ethnic boundary-making mechanisms among adolescence in the school setting. In particular, she examined how intergroup boundaries form and evolve among adolescent friendship networks, and, in turn, how the network embeddedness of immigrant children shapes their identities and integration outcomes.
