Annegret Stephan is a senior researcher in the Group for Sustainability and Technology. Her research centers on technological innovation for a clean energy system with an economic and innovation system perspective. More specifically, she aims to understand how innovation processes unfold—for individual technologies, but also when different sectors and value chains become intertwined. Empirically, she has focused on electricity storage technologies, specifically on mobile and stationary batteries, as well as on the coupling between the electricity and other sectors such as transportation. Annegret’s research has a quantitative focus (e.g., techno-economic modelling, patent data analyses), but she also applies qualitative approaches (e.g., interviews).
Annegret received her PhD from ETH Zurich in 2016, which she already conducted in the Group. As part of her studies, she spent two months at the Department of Science, Technology, Engineering and Public Policy (STEaPP) at University College London (UCL). Annegret holds a degree in Business Engineering (Dipl.-Wi.-Ing.) from the Karlsruhe Institute of Technology (KIT, Germany). During her studies, she spent one semester at the University of Technology Sydney (UTS, Australia), worked as a research assistant at the Institute of Operations Research (IOR) of the Karlsruhe Institute of Technology, and received scholarships from the German National Academic Foundation and the German Academic Exchange Service (DAAD).
Annegret gained practical experience through several internships such as at McKinsey & Company, Deutsche Lufthansa and Metzler Investment GmbH. She enjoys spending time with her family, and likes doing outdoor sports (hiking, mountain biking, skiing/ski-touring) and handicrafts (sewing).
