Martin Aranguren developed, in his PhD at the École des Hautes Études en Sciences Sociales (EHESS), a methodology to integrate the study of emotions in sociological analysis. He studied sociology in Mendoza, Argentina, political science in Lille, France, and philosophy in Leipzig, Germany. He completed a master’s degree in sociology at EHESS and an MPhil in social anthropology at the Centre for Studies in Social Sciences (CSSS) Calcutta. Martin Aranguren’s publications concern the history of dependency theory in Latin America, the mobilisation of “untouchables” in India and, more recently, the structure of emotional situations in the Paris metro and in human–machine interaction.
