This paper is a rough translation of an interview whose publication in French is forthcoming. I would like to thank Marylou Ham, who works with me on this project and who elaborated the questionnaire. The purpose of this interview was to bring my experience as a representative of the Social Science and Humanity (SSH) association at the EU level back to the surface and try to gain some reflexivity from it. The aim was to produce a perspective on the making of European research policy in SHS within Horizon Europe from a situated position. I also wanted to reveal the conditions for mobilising scientific knowledge for action and the effects of this ordeal on the theoretical and practical construction of the field of eurocracy (Georgakakis, Rowell 2013) as a political battleground for worldviews that include visions of societies.
