As a trained cognitive psychologist, I investigate the way in which decision-makers and judges arrive at their conclusions. Oftentimes, I use statistical and computational models to embody assumptions regarding the underlying processes, and process tracing methods to gain further insight into the workings of the mind.

A lot of my work is concerned with risky decisions, but I have worked on a wide variety of choices and judgments, including social dilemmas, personality judgments, and ethical decisions.

Besides the University of Koblenz-Landau, I have close ties to the Max Planck Institute for Research on Collective Goods at which I am an affiliate researcher, and the University of Mannheim, where I am Member of the Graduate School of Economics and Social Sciences.

Research focus

In a nutshell, my work and interests focus on:

  • Cognitive processes underlying judgment and decision making
    • Development and comparison of process models of risky choices
    • Effects of information display on the process level
  • Methods
    • Formal and computational modeling of cognitive processes
    • Statistical model comparisons incorporating process-level data
    • Process tracing using eye-tracking
    • Applications of machine learning and large-scale data analysis techniques in psychology
  • Ethical decisions and their individual and situational determinants
  • Web-based experimentation and online panels
