Wencke Gwozdz has been a Professor of Consumer and Supply Research since 2018 and, since 2021, Vice Dean of the Faculty of Agricultural Sciences, Nutritional Sciences, and Environmental Management at Justus Liebig University Giessen. She earned her Ph.D. in Economics from the University of Hohenheim and spent a decade at Copenhagen Business School in Denmark. As a consumer researcher, her primary research interests lie in sustainable consumption, health behavior, and consumer policy, with a special focus on nutrition. Her work aims to understand the impacts of consumer behavior on individuals, the environment, and society at large, and to identify ways to promote behavioral change. Methodologically, she specializes in quantitative approaches, including surveys, diary studies, and field experiments. Through her extensive experience in European research projects such as IDEFICS, I.Family, Nudge-IT, Trash-2-Cash, and PLAN'EAT, she has built a strong interdisciplinary network.
