User-Centred Social Media

Our group participates in the DFG-funded Research Training Group (Graduate School) “User-Centred Social Media” which aims at developing new models and methods for analyzing, designing and evaluating social media from a user-centred perspective. The main research fields in the RTG are modelling and understanding user behavior, social media engineering, and social media analytics. The program is an interdisciplinary endeavor located in our University department that fully integrates researchers from computer science and psychology. We contribute to the RTG with two PhD topics which lie in the areas of trustworthy recommendations based on social media sources and health-related behavioural interventions.
