Head of the division pedestrian dynamics - social psychology

Social dynamics in large crowds and subjective experiences of participants in crowds are at the center of my research at the IAS-7. Trained as a psychologist and a sociologist, I combine quantitative, experimental methods with more qualitative approaches such as field observations and interview studies. Research questions include:

  • How do participants in a crowd influence each other? Is pushing behavior spread in a crowd?
  • How is density in a crowd experienced? Which factors moderate the relationship between density and comfort?
  • How is perception of others – for example emotional expressions, communicative signs – changed in large crowds?

Curiosity in interdisciplinary work with physicists and computer scientists and the fascinating topic of crowds has moved me to the Forschungszentrum Jülich recently. Since 2020, I am establishing the new division „pedestrian dynamics - social psychology“. At the same time, I am staying connected with the faculty of social science at the RUB where I am working, among others, on parenting in Germany and Turkey.

Currently, I am leading three research projects as PI:

  • CrowdDNA. Technologies for Computer Assisted Crowd Management (parental leave replacement for Dr. Juliane Adrian) (2020-2024), EU, FZJ more...
  • CroMa. Crowd-Management in Traffic Infrastructures (2018-2022), BMBF, RUB more...
  • Cultural Transformations and Popular Scientific Adaptations of Psychological Knowledge by Parents in Turkey. A Qualitative Study (2019-2022), DFG, RUB more...

Teaching: I am teaching and supervising students at the faculty of social science, RUB, covering the areas of cultural and social psychology, cultural and social theory, qualitative and quantitative methods, crowd psychology.
