Astrid is an assistant professor at the School of Sustainability, Leuphana University Lueneburg, Germany. She is associated with the Harding Center for Risk Literacy at the University of Potsdam, Germany.

Astrid studies the cognitive and social mechanisms driving risk perception and decision-making under uncertainty. She explores those in the context of climate change, biodiversity loss as well as nuclear weapons and nuclear war. This includes the heuristics that individuals use to make decisions in face of challenges such as climate change and nuclear war.

Drawing on the science of science communication, her research also explores how risks and uncertainties can be communicated transparently and understandably. Her work aims to make citizens better able to deal with risk and uncertainty.
