I work on how ideas spread and develop in different contexts, on the intersection of discourse analysis, history of concepts, and sociology of knowledge. At the moment, I am doing so by studying the diffusion of the political concepts of the indigenous movement in Ecuador -Buen Vivir/Sumak Kawsay at the centre- and the development of Ecuadorian sociology in relation to global sociology and other national/local traditions. Research interests are: indigenous and social movements, decoloniality, identity, social exclusion, systems theory, political sociology, sociology of science.
