Communication and roles of scientific experts in social media during the Covid 19 pandemic.

The communication of scientific experts via social media is an important development in science communication. Scientific experts can communicate directly with political, media, and social actors through their own social media channels. The boundaries between different public arenas are becoming increasingly blurred in the online environment. In her cumulative dissertation project, Kaija Biermann uses the Covid 19 pandemic as an example to investigate what this means for the communication behavior and roles of scientific experts. During the first two years of the pandemic, scientific experts in the field of virology were the main actors shaping the public debate. They also used their own social media channels to communicate with the public. In order to be able to make statements about the communication behavior of scientific experts in the social media, a quantitative content analysis of contributions of visible experts on Twitter will be carried out. In addition, the expectations and evaluations of laypersons regarding the communication of scientific experts in social media will be examined more closely in focus group discussions. Finally, the own understanding of the role and the perceived role attributions will be examined with the help of qualitative interviews with scientific experts. Through the empirical investigation of different dimensions of roles, (changing) roles of scientific experts in digital communication environments will be considered holistically.
