I am broadly interested in the evolution of morality and theory of mind abilities. My PhD focusses on the one hand on a better understanding of social evaluation in common marmosets – a prerequisite for morality and theory of mind abilities. To do so we combine a novel experimental approach and thermography as a non-invasive method to assess arousal levels.
Moreover, I am interested in how marmosets coordinate cooperative actions in their family groups, especially in the case of vigilance behavior. Not all group members contribute equally to vigilance duties in marmoset family groups. We conduct experiments in novel environments to better understand, why and how these differences occur.
