Abstract
This chapter examines the identity work that takes place within public communication of science. Using a conceptualisation of identity as performance – and thus as something that may be done differently within different contexts – it uses the case of a large science festival, Science in the City, which took place in Copenhagen in 2014, to examine how scientific identities can be enacted in science communication. The key argument is that such communication supports multiple and flexible identity performances. Scientific identities are intertwined with other ways of performing the self, and both audiences and communicators are heterogeneous communities, which do not neatly sit in categories of ‘scientists’ or ‘the public’. Ultimately, it appears that science communication is used by scientists for many different identity-building purposes, in many different ways.
