As a member of the research association InChangE (Individualization in Changing Environments) between Bielefeld University and the University of Münster, I focus on mathematical modelling of causes and consequences of individualisation in changing environments. My research goal is to investigate the role of individualisation in ecological and evolutionary processes, as well as in economic processes such as digital transformation of the markets, with the help of individual-based models on the intersection of biology and economics, and to intensify cross-fertilization between the two disciplines.
