Sarah Diefenbach is professor for Economic Psychology and Human-Computer Interaction at the Ludwig-Maximilians-Universität München (Germany) with a focus on the field of interactive technology. Her research group explores design factors and relevant psychological mechanisms of technologies related to different facets pervasive computing (e.g., smart communication, self-improvement technologies, social media, companion technologies, social robots). Sarah Diefenbach received her doctorate in Psychology with distinction from the University of Koblenz-Landau. Since 2007 she is engaged in research on user experience and consumer experience in the field of interactive products. Current research topics focus on the negative side effects of technology use on happiness and wellbeing ("digital depression"), the psychological effects of social media (e.g., selfie-paradox) as well as interaction design from a psychological perspective (e.g., aesthetics of interaction, psychological needs approach). Sarah Diefenbach developed several methods for user experience design and evaluation (e.g., interaction vocabulary) which are widely applied in research and practice. She has acquired and led a number of interdisciplinary research projects by research foundations (BMBF, DFG) as well as industry partners.

Sarah Diefenbach is an active member of the scientific community, is member of several editorial boards (e.g., i-com – International Journal of Interactive Media), has co-organized several events and conferences (e.g., Usability Professionals, Mensch & Computer) and served as program committee member and reviewer in leading conferences in the field of HCI (e.g., CHI, DIS, Mobile HCI). Her research is internationally published and recognized, including more than 100 articles in books, journals, and conference proceedings. She is an acknowledged speaker with a number of invited talks for keynotes and panel discussions on academic, industry-oriented and cultural events.
