Partial research of the project El escepticismo pirrónico-empírico y el escepticismo académico en su desarrollo histórico [...] (EPADMECO), which explores the work of contemporary artists Ghada Amer and Chiharu Shiota, who have redefined thread as a graphic element of expanded drawing (embroidered line and in space) to create a sceptical discourse: artistic images that induce doubt, knowledge, as opposed to the dogmatic ones that invade us from post-truth. Part of the field study resulting from research stays at the Centro Nacional de Arte Contemporáneo Reina Sofía and the Museo Nacional de Artes Decorativas.
