📢 I am organizing the BIGSSS Summer School in Computational Social Science July 3-12, 2023 in Bremen. We combine it with a research incubator. The topic this year is the Democratic Debate.
📢 I am organizing the Interdisciplinary Workshop on Opinion Dynamics and Collective Decision 2023 ODCD’23 July 12-14, 2023 in Bremen. 💭💬🗯️🗳️
I am a computational social scientist who works on the modeling, analysis, and design of socio-economic systems. I work as an assistant professor in social data science at Constructor University in Bremen.
More about me
I am particularly interested in the dynamics of opinion and attitude formation and how it influences democratic collective decision-making through deliberative interaction. I see opinion dynamics as an interdisciplinary topic because it touches on social psychology, game theory, and the dynamics of complex systems. It is on the one hand driven by automatic cognitive and emotional processes, on the other hand, it has elements of a strategic game, especially in the run-up to a poll, an election, or other collective decision. Finally, interaction in large groups can have surprising systemic effects on macroscopic outcomes going beyond the scope of the individual.
I want to contribute to detecting such self-driven hidden dynamics to better understand phenomena such as polarization, the evolution of plurality, social cohesion, consensus, and extremism in opinion landscapes.
I want to find democratic innovations to aggregate the wisdom of the crowd (if it exists) in collective decisions under circumstances of ongoing opinion dynamics and strategic behavior of many people.
I studied at the University of Bremen, where I also finished my doctoral studies in 2007. I was a post-doc at ETH Zurich at the Chair of Systems Design until 2009 and a scientist, lab manager and lecturer in political and social sciences at the at University of Oldenburg. I am with Constructor University (which was called Jacobs University Bremen until 2022) and the Bremen International Graduate School of Social Sciences. I also worked at the Computational Social Science Department at GESIS and the Complex Systems Lab at the University of Bremen.
I spent time developing and performing in a traveling youth theater, juggling clubs and balls, and playing board games. I live with my family in Bremen.
