Óscar J. Martín García is a Tenured Scientist at INGENIO (CSIC-UPV). He obtained his PhD in History from the University of Castilla-La Mancha (2006) and has developed his professional career at various national and international institutions, including the London School of Economics, Georgetown University, Aarhus University, the Spanish National Research Council (CSIC), and the Complutense University of Madrid, through competitive research programmes such as JAE-DOC, Marie Skłodowska-Curie COFUND, and Ramón y Cajal.

His career has resulted in a versatile and multidimensional research agenda that connects local, social, and international history with emerging lines of inquiry in the history of science and technology. The second half of the twentieth century constitutes the main historical framework of his work, spanning from Francoist Spain and the democratic Transition to the global challenges and geopolitical rivalries of the Cold War.

His research lines include the study of mobilisation, social protest, and regime change in Spain (1958–1982); the international dimensions of Southern European democratizations in the 1970s; British and US public, educational, and scientific diplomacy towards Spain during the Cold War; as well as cultural exchange programmes and their relationship with global networks and the transnational circulation of knowledge. He has also worked on international organisations and the global development project after the Second World War. He is currently conducting research on the space diplomacy of NASA and the European Space Agency (ESA) in Spain (1958–1986).

The results of his work include more than fifteen articles in high-impact international journals — including Contemporary European History, Cold War History, Social Movement Studies, Democratization, and International History Review — as well as leading Spanish journals in the field (Historia y Política, Ayer, Hispania, Historia Contemporánea, Historia Social). He has also published more than twenty book chapters with prestigious publishers such as Palgrave, Routledge, Comares, and Sílex, in addition to two research monographs and three co-edited volumes published by Los Libros de la Catarata, De Gruyter Oldenbourg, and Berghahn Books. He is currently preparing a monograph for Vanderbilt University Press.

Alongside his research activity, he holds management responsibilities as Secretary of the INGENIO Faculty Board and Coordinator of the Focal Area “Cultural Dimensions of Science and Innovation Studies.”
