My main area of research is the conflict in Northern Ireland, and more particularly Sinn Féin and the IRA, on which I have published many books and articles. I also work on post-conflict politics, covering areas such as victims and reconciliation, the legacy of violence,
I also research contemporary Irish society, as well as multiculturalismalism in France and Ireland, and am I currently working on issues of asylum seekers in the French and Irish contexts.
