This study aims to provide a complex account of a PhD candidate's reflexive doctoral engagement process emergent from the changing doctoral environment vis-à-vis the neoliberal higher education context. Drawing on a critical realist theory of reflexivity, it analyzed narrative interview data collected with the participant over an 18-month period. The analytical focus was on how the student's reflexivity mediated her exertion of agency within the structural affordances and constraints of her doctoral education to ultimately give shape to a unique doctoral trajectory. Findings revealed that the participant practiced distinct patterns of reflexive deliberations in three disparate but interweaving areas of her doctoral life: research progression, community belonging, and career construction. Notably, analysis highlighted the contingent and fluid characteristics of the reflexivity phenomenon and its context-dependent effects in the complexity of doctoral study. The study argues that a sociological view of reflexivity offers a novel means to understand the nuanced ways of agency-structure interplay pervading experiences of contemporary candidature.
