The present study used a longitudinal mixed-method design to investigate the relationship between post-PhD researchers’ writing conceptions and their experiences, scholarly trajectory, and networking capabilities. A total of 134 Spanish post-PhD researchers answered the Post-PhD Experience—Survey scales on Academic Writing and Social Support. One year later, a subsample of 21 participated in retrospective multimodal interviews, in which visual methods (Journey and Network Plots) were applied to analyse their writing trajectories during this period of time. The person-centred analysis revealed three post-PhD profiles regarding writing conceptions and evidenced differences among them in the way they participate in the research community and interact with other researchers. Qualitative results suggest the post-PhD researchers in each profile position themselves in the community differently and subsequently engage in distinctive writing experiences. The study provides evidence of how writer profiles appear to mediate trajectories and networking, something not evident when using only sectional designs. Relational agency is revealed to be an important aspect of productive writers. Pedagogical implications are discussed, particularly the need to promote writers’ awareness on how their writing conceptions intertwine with their strategic management of research writing practices in different contexts.

本研究使用纵向混合方法设计来调查博士后研究人员的写作概念与其经历、学术轨迹和网络能力之间的关系。共有 134 名西班牙博士后研究人员回答了博士后经历——学术写作和社会支持调查量表. 一年后，21 人的子样本参加了回顾性多模式访谈，其中应用视觉方法（旅程和网络图）分析了他们在这段时间内的写作轨迹。以人为本的分析揭示了三个关于写作概念的博士后档案，并证明了他们在参与研究社区和与其他研究人员互动的方式上存在差异。定性结果表明，每个档案中的博士后研究人员在社区中的定位不同，随后从事独特的写作体验。该研究提供了作者简介如何调节轨迹和网络的证据，这在仅使用截面设计时并不明显。关系代理被证明是多产作家的一个重要方面。
