McAleese has a long-standing involvement in ecumenism and anti-sectarianism. She co-chaired the working party on sectarianism setup by the Irish Inter-Church Meeting in 1991 and its report (1993) was described by Professor Marianne Elliot as "the most notable" work of the Inter-Church Meetings. McAleese was the author and presenter of a successful BBC Radio Ulster series called "The Protestant Mind" which encouraged the divided communities in Northern Ireland to try to stand in each other's shoes. McAleese was a member of the Catholic Church Episcopal Delegation to the New Ireland Forum in 1984, and a member of the Catholic Church delegation to the Northern Ireland Commission on Contentious Parades in 1996. She was also a delegate to the 1995 White House Conference on Trade and Investment in Ireland and to the subsequent Pittsburgh Conference in 1996. She became the Pro-Vice-Chancellor of Queen's University Belfast. Prior to becoming president in 1997, McAleese had also held the following positions: Channel 4 Television, Director, Northern Ireland Electricity, Director, Royal Group of Hospitals Trust and Founding member of the Irish Commission for Prisoners Overseas.
