This chapter focusses on the highly multilingual and international University of Luxembourg and aims at examining how doctoral students and supervisors perceive different dimensions of supervision, the academic language use and the development of an academic identity. Interviews with seven supervisors and 12 doctoral students (from different nationalities) from the faculty of social sciences and humanities were conducted, transcribed and interpreted on the basis of thematic analysis. The results show that a multitude of research and supervision traditions/styles influence the Luxemburg research and supervision practices in a way that makes it hard to identify a common reference point (no national norms) on the one hand; but, on the other hand, it shows new ways of combining different academic cultures and languages for research. This highly diverse environment, coupled with the increased dominance of English, seems also to have an effect on the identity formation of the student-researchers. That is, they tend to identify themselves as international rather than as European.
