Abstract
Neoliberalisation of academia has led to an increasing recruitment of doctoral students in teaching roles. Whilst there is evidence of doctoral students being engaged in teaching roles and the reasons for doing so, there is a pressing need to understand their experiences and to develop effective support practices to help them in their roles as teachers. Using borderlands theory as a lens, the thematic analysis of case study data from doctoral students in two English universities indicates that although they were navigating similar borderlands, the structural inequalities posed by their institutions led to differential support for their teaching roles and teacher identity development. The paper highlights the need for aligning doctoral roles to academic roles. It concludes by challenging the precarious support available for doctoral students, and proposes recommendations for the holistic development of doctoral students as competent and successful teachers (and researchers) in an increasingly precarious academia.
