Collaborative and Participatory Research (CPR) presents different challenges for doctoral students, compared to other researchers. Even under ‘normal’ circumstances, engaging with CPR poses intricate practical and ethical challenges. For instance, understanding CPR or forming alliances to co-create knowledge can be particularly challenging. Moreover, the increasing popularity of CPR within universities is not always accompanied by sufficient training in these approaches for doctoral students. In this paper, we first present reflections on a participatory research project developed by one of the authors during the COVID-19 emergency. Specifically, we discuss the difficulties faced during their PhD fieldwork in Santiago, Chile, in 2020. One of the main obstacles was the need for a university network of peers to support and facilitate discussions regarding practical and ethical issues that emerged during the collaborative process. Secondly, we present our reflections on our shared experience of participating in and facilitating an interdisciplinary and inter-university reading group about CPR. This group was set up due to a need for more spaces to discuss CPR and an ongoing need for an in-person doctoral community in the hybrid post-lockdown world. We ask and reflect upon two questions: how can we negotiate the tensions involved in employing CPR during and after the COVID-19 emergency to produce an individual PhD thesis? How can an in-person community help us to navigate ethical and practical challenges? We suggest the significance of enabling community-driven, student-led spaces that foster interdisciplinary collaboration within universities. In particular, we advocate for dialogic spaces to discuss ethical issues and express shared vulnerabilities. We suggest that these spaces can help to nurture reflexive openness to new and unexpected possibilities in research. Such spaces are particularly important for tackling the complexities of CPR.
