Main Focus

Head of Research Area Boosting Decision Making

I study how to boost human judgment and decision making online and offline by understanding human and machine behavior. I combine insights and methods from cognitive science, collective intelligence ("wisdom of crowds"), heuristics, and algorithms. I also work on applications in digital environments, medical decision making, and meteorology. Furthermore, I am co-leading an initiative on reconfiguring behavioral science for crisis knowledge management in response to COVID-19 and other, future disruptive events (
