I studied cognitive science at the University of Tübingen, Germany (B.Sc. and M.Sc. in cognitive science). Subsequently, I pursued my PhD at the LEAD graduate school at the University of Tübingen and the Leibniz-Institut für Wissensmedien in Tübingen. In 2020 I moved to Greifswald, Germany and became a postdoctoral researcher at the University Medicine Greifswald. I joined the Centre for Mathematical Cognition at Loughborough University in 2022.
