    Caucasus / Georgia


    Dr. Medea Badashvili is Associate Professor in Human Geography and Head of the Master Programme in Gender Studies at Ivane Javakhishvili Tbilisi State University, Georgia. Holding a PhD in Human Geography, her research spans labour migration, refugee flows, gender equality, domestic violence, and women's political and economic empowerment in Eastern Europe and post-Soviet contexts. Her current research, supported by a DAAD fellowship at the University of Göttingen, examines the lived experiences of Ukrainian refugee women in Germany and Georgia, exploring how displacement reshapes power dynamics, family decision-making, and cultural identity. Her comparative work across post-Soviet states and Georgia, combined with deep expertise in gender and migration, makes her a vital contributor to GIEHM's research on the reproductive dimensions of forced displacement.

  • Post-Doctoral Researcher Polina Vlasenko
