My research is divided into 2 main categories: contemporary political philosophy and the history of political ideas from the Renaissance to the 19^th century. These 2 categories also reflect the content of my courses and seminars.

In contemporary political philosophy, my work deals with questions of post-war transitional justice (rebuilding institutions, penal justice, truth and reconciliation commissions, collective memory, etc.), where my main theoretical interests are the issues of collective responsibility and democratic deliberation. Generally speaking, my research - both on social justice and democracy issues and on immigration - is in line with work on neo-republicanism. In moral philosophy, I take a consequentialist approach.

My publications on the history of ideas deal with relations between political freedom and authority, from the 15^th to the 19^th centuries, more specifically on the republican tradition since the Renaissance. In that connection, I have focused particularly on the work of Machiavelli, Jean Bodin, Hobbes and Rousseau.

My research concerns the theory of recognition of persons and peoples. I am trying to determine to what extent politics of recognition can fit with a liberal-inspired political philosophy. The hypothesis I am studying is that politics of recognition must take the form of a regime of individual and collective rights.

I am also studying the relationships between nationalism and liberalism. In that context, the focus must be on examining the collective right of peoples to self-determination. Nationalism is perhaps just the attempt to secure that right. Thus understood, nationalism and liberalism can become compatible. In the philosophy of language, I am interested in the concept of linguistic community. This approach would make it possible to take into account the collective dimension of language, whether it is related to peoples or other kinds of national groups.
