Research Associate at the chair for Experimental and Theoretical Psychology, Heidelberg University
I am interested in how people make decisions in the context of dynamic systems and complex situations, particularly in the field of climate change. I am also interested in interdisciplinary research with behavioral economics, particularly concerning the question how individual cognitive resources such as working memory influence behavior when dealing with common property resources.
