The purpose of this thesis was to explore the co-creation process between citizens and researchers in a workshop series designed to support the communication of research-related topics to audiences beyond academia. The study focused on participants' experiences of participation, dialogue, collaboration, and learning, as well as the perceived influence of the co-creation process on communication practices and materials. The study was limited to the experiences of citizen panelists and researchers who participated in the workshop series.

The theoretical framework drew on literature related to societal impact, stakeholder engagement, science communication, and co-creation. Particular attention was given to factors that support collaborative processes, including facilitation, trust, psychological safety, meaningful participation, psychological ownership, and reciprocal learning. The study was conducted as a qualitative case study in 2026. Data were collected through workshop observations, participant discussions and comments, facilitator notes, and post-process surveys conducted with citizen panelists and researchers. The data were analyzed using a thematic approach that focused on identifying recurring themes and shared experiences.

The findings indicate that the workshop series was experienced as open, inclusive, and collaborative. A trusting and psychologically safe environment supported dialogue and enabled participants to share perspectives and provide feedback. Both citizen panelists and researchers perceived their participation as meaningful and felt that their contributions influenced the development of communication materials and approaches. The workshop series also facilitated reciprocal learning: citizen participants gained a greater understanding of research and scientific work, while researchers developed a deeper understanding of public perspectives and the communication needs of non-specialist audiences. The findings suggest that co-creation can strengthen dialogue between citizens and researchers and support the development of more accessible and relevant communication practices.
