Mari Christine Fitzduff is an Irish-born activist, policy maker, educator, writer and academic. She is the Founding Director of the MA Conflict and Coexistence Programme at Brandeis University, Massachusetts, USA, which began in 2004.
Mari Fitzduff helped to set up the first courses in conflict resolution in both universities in Northern Ireland. She authored a training book in 1988, which could be used particularly in the conflict in Northern Ireland, called Community Conflict Skills. It has since been translated into Indonesian, Serbo-Croatian, Spanish, and other languages in countries rife with ethnic strife. It gives over 50 ways of looking at issues of justice, political choices, and bridge building.
From 1990 to 1997 she was the Founding Director of the Community Relations Council, which was funded by both British and European funds, but was independent. It developed and funded many of the conflict resolution initiatives in Northern Ireland.
From 1997 to 2003, she was the Director of UNU/INCORE, a joint initiative of the United Nations University and the University of Ulster, where she held a chair in conflict Resolution. UNU/INCORE conducts policy relevant international research on conflict issues around the world.
She is the founding director of the MA Program in Coexistence and Conflict at Brandeis University. This is an international program, for experienced professionals, which began in 2004, and so far has had students from over 70 countries world wide.

Nobody wants the final compromise to come too quickly ... because it's the end of the dream for both sides. It will have to be a perforated border as opposed to a united Ireland. And unionists will have to abandon dreams of unity forever with the motherland ... Sinn Féin will sell the compromise on the basis of its being a transitional agreement. People really are quite weary of the war
