A second contribution to the conference was at a panel on "Analysing European Security Through the Concept and Practice of Tinkering", organised by Jasper van der Kist (European University Viadrina) and Rocco Bellonova, which included contributions from Vanessa Ugolini, Jonathan Austin, and Anna Leander. This panel investigated the tinkering as a both a site and method of research. Ruben presented how he works with the notion of critical re-modelling, developped by [Shintaro Miyazaki](https://amor.cms.hu-berlin.de/~miyazash/), to investigate computer vision technologies.
