Prof. Trier investigates phenomena of electronic communication and social influence effects in online media within and outside the organisation using a mixed methods approach that combines quantitative, qualitative and network analytical methods. Example topics include the implementation/application of social media, online participation, the design of electronic discourses (e.g. from a management perspective), information transfer, dissemination processes or bottom-up community development in the context of knowledge management initiatives. A particular methodological focus is the development of an event-driven method for dynamic network analysis (see corresponding softwarewww.commetrix.net). It enables research into new structures and dynamic processes of human networking.
