Irrespective of national and disciplinary specicities (Le Feuvre et al 2018), the conditions of entry to an academic career are generally recognized as being increasingly selective in the contemporary context. In the competition for a reduced number of stable or permanent academic positions, recently qualied PhD graduates who want to pursue an academic career face two main challenges. On the one hand, they have to accept a succession of xed-term, often part-time and badly paid, precarious positions (generically designated as ?postdocs ?), that have become a prerequisite for selection to more stable and permanent positions in the global academic labour market. On the second hand, access to these positions usually requires some form of geographical ? usually transnational ? mobility, which removes them from their existing social networks. In this chapter, we propose to analyse the eects of the combination of precarious employment positions and geographical displacement on the gendered citizenship experiences of postdocs working in a specic academic context. On the basis of qualitative (biographical interview) and quantitative (on-line web survey) data collected in the course of the GARCIA project (www.garciaproject.eu), we will examine the citizenship challenges faced by postdocs from across the globe who are working in the Swiss academic context.
