Her research started from the thought of Michel Foucault, to whom she has devoted a dictionary, several books and many articles, especially around two themes - the relationship between philosophy of language and literature, and the transition from biopolitics to subjectivation. She is linked to the work of the American philosopherArnold Davidson, with whom she has in common an attempt to update the ethico-political Foucaldian themes. After the 2005 French riots, she gave a book about the so-called "banlieues" criticizing both the clichés that surrounds its inhabitants and the growth of racism in the French society. She tried to analyse the refusal to give any political value to what was happening in the suburbs by deconstructing racist implicit images of public speeches. Since the beginning of 2010, she has been working more generally on the philosophy of history, and especially the way in which a certain practice of philosophy has problematized both its own historical situation and the possibility of intervening in the present. In this context, she develops a work on the philosophical use of archives, especially through teachings and seminars at the EHESS. More generally, she studied the different representations of history in French thought since the 1950s. It also extends its investigation of some Italian readings of French poststructuralism. Finally, she develops a series of theses on the political theorizations before and after 1968 and on the necessary recasting of the political concepts of modernity, in the silage of Italian operaism and more particularly the analyzes of the philosopher Toni Negri, her husband. She works in particular on the notion of "common" as an alternative to the public / private dichotomy, and on a political ontology of the present building bridges between Maurice Merleau-Ponty and Michel Foucault.
