This paper develops a methodological framework for event-ethnographic research in online and offline settings based on the authors’ ethnographic experiences in the fields of environmental governance and sociotechnical transition before and during the COVID-19 pandemic. Drawing on empirical event studies, we outline the particularities of organized events as ethnographic research sites, identifying key challenges related to the spatio-temporal ephemerality, socio-material infrastructures and interactive unboundedness of events. We address these challenges along three axes of reflection, asking how we (1) attend, (2) infrastructure, and (3) take part in organized events. The framework we propose promotes a co-constructive understanding of organized events and raises broader methodological issues regarding power dynamics, our role as ethnographers in transdisciplinary contexts and fair and transparent ethnographic data collection. The framework is designed to explore how the (post-)pandemic transition from real-world to virtual event interactions affects both our research fields and our ethnographic research in transdisciplinary contexts.
