This practice insight paper presents a reflection on a four-year collaboration between science communication practitioners and researchers, using CERN's new education and outreach centre as a case study. The development of interactive exhibitions for this centre was informed by a variety of front-end and formative evaluation studies, from online surveys to exhibit prototype testing. As a multidisciplinary team of exhibition developers and social science researchers, we describe and discuss the challenges of — as well as learnings from — working together. Our experience will be relevant for everyone curious to discover `behind-the-scenes' work of research-informed exhibition development in a large scientific laboratory.
