I am a postdoctoral research fellow at the University of Mannheim School of Social Sciences. Before, I was a senior research fellow at the Max Planck Institute for Research on Collective Goods. My general research interests focus on conditions under which social norms change and emerge, particularly the effects of social feedback and contextual information on perception and conformity to social norms. Most of my work has been concerned with social norms stigmatizing the overt expression of prejudice, such as racism, xenophobia, or sexism. Social norms against the public expression of views considered politically incorrect developed over the last decades and constitute a powerful deterrent to the expression of prejudice in modern societies. In my current research, I investigate the role of social norms as a bulwark against hate speech online, how anti-prejudice norms are affected by sudden events, or how populist political rhetoric can undermine these norms. In my research, I make use of a wide range of experimental and quasi-experimental methods, including original lab-in-the-field online experiments, but also survey and lab experiments. My work has appeared in European Sociological Research, Proceedings of the National Academy of Sciences, and Sociological Research.
I completed my PhD at the Faculty of Management, Economics and Social Sciences at the University of Cologne and worked as a junior research fellow at the MPI for Research on Collective Goods. I was also part of the International Max Planck Research School on Adapting Behavior in a Fundamentally Uncertain World, and a visiting fellow at the Norms and Networks Cluster (NNC) at the University of Groningen, Netherlands, and at the department of Sociology at New York University (NYU).
