When Yusuke Sakurai draws his career as a river, it doesn't flow in a straight line. There are bends and rapids, confluences where other currents join, and calm stretches where the water finally settles—a visual metaphor that captures something universities rarely acknowledge: becoming an independent researcher isn't a finish line you cross with a diploma.
A new study from Hiroshima University, published in May 2026, challenges the widespread assumption that a PhD marks the moment when scholars become truly independent. Instead, the research reveals that independence unfolds as a long, uneven, lifelong process shaped as much by relationships, institutional structures, and luck as by individual effort and talent.
Sakurai, an associate professor at Hiroshima University's Center for Academic Practice and Resources and Research Institute for Higher Education, led the study alongside colleagues from the University of Glasgow, Anglia Ruskin University, and the University of Oxford. The team used an innovative method called the "river of experience"—combining collaborative autoethnography with visually guided interviews. Six researchers at different career stages—doctoral, early-career, and mid-career—literally drew their academic journeys as rivers, documenting how independence actually feels when you're living it.
What emerged from these portraits is a more honest picture of academic life. Independence is not a milestone but a bumpy developmental process marked by uncertainty, setbacks, and gradual growth. It's shaped by critical experiences: a conference presentation, a job search, a rejection, the dynamics of a supervisor relationship, or the chance to mentor someone else. Importantly, it's also agentive—researchers actively build skills, advance expertise, and navigate their own paths through varied engagements rather than passively waiting for institutions to anoint them.
But here's what makes this study particularly illuminating: independence is created and affirmed through both internal validation and external recognition. This is where institutional power becomes visible. A researcher might develop genuine expertise and self-direction, yet still struggle to feel independent if they lack freedom in choosing projects, face precarious employment, or encounter supervisors who limit their agency. Even experienced mid-career researchers can feel constrained by systems that don't grant them real autonomy.
The study's findings point to three core dimensions. First, independence is not linear—it's bumpy, with periods of rapid growth followed by plateaus or setbacks. Second, it's self-directed; researchers author their own development rather than having it imposed. Third, it emerges from the interplay between what researchers do internally and what the wider academic system permits or denies them.
This reframing matters profoundly for universities and research institutions globally. If independence isn't a single achievement but a dynamic, lifelong process, then institutional approaches to training, mentorship, employment structures, and research culture need rethinking. The current system treats the PhD as a finish line when it's actually a starting point on a much longer, more complicated journey.
Looking forward, Sakurai and his team hope to expand this research across disciplines and contexts, using longitudinal designs to trace how researchers of different backgrounds negotiate independence in varied settings. As the global research community grows and evolves, understanding independence not as a destination but as an ongoing navigation—shaped by relationships, structures, and the choices researchers make within them—offers a foundation for building more sustainable and intentional paths to genuine scholarly autonomy.
