Stefanie is an assistant professor at the University of St. Gallen. In her research and teaching, she is interested in how to use concepts and theories from marketing, psychology, and behavioural economics to better understand consumer behaviour, with a focus on energy consumption and mobility. Several projects she is involved in focus on evaluating concrete intervention strategies to promote energy savings, including the designing of energy labels for household appliances and cars, the designing of electricity tariffs, and the effectiveness of behaviour change campaigns such as a specific campaign where people are encouraged to exchange car keys for a free trial on an e-bike.

From 2008 - 2012, Stefanie was a PhD student at the University of St. Gallen and worked as a research associate at the Institute for Economy and the Environment.

During this time, she led the advocacy work of BEUC on European policies for sustainable transport topics where she was responsible for representing consumer interests in the process of policy-making and also for influencing European legislation towards consumer-friendly and sustainable policies.
