Xavier Roqué trained as a physicist and did his post-doctoral research at the University of Cambridge and the Centre de Recherche en Histoire des Sciences et des Techniques, La Villette, Paris. His research focuses on the history of physical sciences in the twentieth century, focusing on the relation between physics, culture, and politics. Together with Néstor Herran, he edited La física en la dictadura. Físicos, cultura y poder en España, 1936-1975 (UAB, 2012). His current research deals with the history and current relevance of small science: disruptive knowledge produced by small teams with modest resources. He has helped to devise and now coordinates a new degree in Science, Technology and the Humanities (UAB-UAM-UC3M), the first of its kind in Catalonia and in Spain. He acknowledges the support of the Spanish Ministry of Science and Innovation, project PID2019-105131GB-I00.
