He has been the founder and co-editor with Rob Walker of International Political Sociology one of the journals of the International Studies Association published by Oxford University Press. He is co editor of the Routledge collection International Political Sociology, and the Routledge collection liberty and security.
His areas of interests are:
* Critical Security Studies (CSS) -the PARIS school: Political Anthropological Research on International Sociology
* Thinking in terms of relations and process: Reframing the international as dynamics of power. Lessons from and across the paths opened by Norbert Elias, René Girard, Michel Foucault, Pierre Bourdieu, and Bruno Latour
* Theory of boundaries and limits : methodologies implying reflexivity of knowledge, working as a collective intellectual. Deconstructing the individual curriculum- the ownership of ideas- the neo liberal academia and its « productivism ».
These lines of research have been experimented through specific enquiries on the conditions of possibilities of freedom in contemporary societies and the practices they generate. At the limits of freedom, how are constructed and articulated the dispositifs of violence, mobility, security ? How transnational professional fields emerged through the specialisation of their management and how they relate to politicians and to politicisation of people? How a « beyond » of the reason of state reconfigure the boundaries of what means national security, public and private sphere, internal and external borders?
Empirically from the 1980s to now, the focus has been around the development of policing activities transnationally, especially in Europe and in the Transatlantic area.
