His main lines of research take into account power relationships and how they affect the production of subjectivities and spaces. All this theoretical approach is developed in three fields: a) the state violence through the political-punitive practice of torture; b) the production of mobility regimes and the experience of travel-displacement in situations of migration and tourism; and c) the political ecology as a theoretical approach to analyze the production of natures.

En torno a una sociología de la mendacidad (Lengua de Trapo, 2006; translated into italian: Elogio della menzogna. Tropea Editore, 2008), El jardín biotecnológico. Tecnociencia, transgénicos y biopolítica (Los libros de la Catarata, 2006) and Inhabit the uninhabitable. The political-punitive practice of torture (Bellaterra, 2014).
