In light of the prominent role of socio-materiality in contemporary social scientific, and particularly educational research, this article uses two practice-based theories to investigate the experiences of German business management professionals on a U.K.-based DBA delivered in Germany. We specifically take concepts from cultural historical activity theory and actor network theory to explore the evolving relationships between professional and academic identities as revealed in qualitative interviews with individual students and supervising faculty. The discussion underlines the potential of these theories to produce rich understandings of the identity formation of researching professionals. We conclude that professional doctorates should be seen not just as specific forms of advanced professional training but as complex and indeterminate processes. Findings suggest that earning a professional doctorate degree often feels like a journey leading to some form of metacognitive shift from a problem-solving mindset to a more critical appreciation of different ways of knowing.
