What do literacy events look and feel like for doctoral students, and how do these events overlap intertextually, materially and relationally? The last three decades have seen a rapid diversification in doctoral education where new opportunities for study, combined with an increasingly competitive landscape, have disrupted what it means to undertake a doctorate, as well as reshaping the literacy practices that comprise doctoral experiences in new ways that have not been fully explored. To understand literacies in new ways, we put to work the construct of literacy‐as‐event, and engage ideas from assemblage theory, to theorise the relationality of literacy practices. Crucially, our study seeks to examine how literacies are emergent and entangled within a wider network of relations. This article draws on data from interviews involving critical incidents with 12 doctoral students, in order to unpack the literacy moments, beyond the thesis, that comprise students' experiences. Our data suggest that we can understand doctoral literacies, not as bounded occurrences, but as assemblages of practices. We contend that thinking with concepts of assemblage and of event offers new insights into the evolving experiences of doctoral students, as well as offering an enriched understanding of literacies and literacy research.
