This presentation delves into my involvement in various facets of contemporary research on migration, integration, and racism. On the theoretical front, I emphasize the importance of paying more attention to the micro-macro links that underlie these phenomena, drawing on analytical sociology. On the empirical side, I outline how advances in network analysis and agent-based modelling allow us to address these links more seriously, while also highlighting the merits and potential of recent large-scale longitudinal data, such as that from CILS4EU. Concerning the infrastructure, I introduce the German Center for Integration and Migration Research (DeZIM), a relatively new and distinctive research institute in Berlin fostering dialogue between different paradigms and engaging with non- academic stakeholders. In particular, this dialogue has led to the initiation of the National Discrimination and Racism Monitor (NaDiRa) in Germany. In this talk, I provide a brief overview of all these developments and discuss their interconnectedness.
