From April 10 to April 22, we had the pleasure of welcoming Stephen Hilgartner as a visiting scholar to the INNORES project. His stay provided an invaluable opportunity for intensive exchanges with the project team on a wide range of themes central to our research. Over nearly two weeks of discussions, workshops, and informal conversations, we explored different facets of innovation residues, from questions of long-term responsibility and care to issues of knowledge production, governance, and future-making. Stephen’s insightful comments, critical engagement, and longstanding expertise in STS helped sharpen our thinking and opened up new perspectives for the project’s ongoing work. The visit was marked by a spirit of intellectual curiosity and collaboration, leaving us with many ideas to pursue in the months ahead. We are deeply grateful for this stimulating exchange and look forward to continuing the conversation.
