Research Interests

Research interests include Irish palaeography and codicology, Irish manuscript tradition, and the history and materiality of the Irish book, on which he publishes extensively. He also conducts research on the early history of paper (watermarks.ucc.ie) and ink in Ireland. Prof. Ó Macháin was responsible for directing the Irish Script on Screen (ISOS) digitization project from its foundation at the Dublin Institute for Advanced Studies (www.isos.dias.ie). In addition to teaching undergraduate courses in palaeography, late medieval poetry, and textual history, he conducts two weekly graduate research seminars in UCC, on bardic verse (Semester 1) and on late medieval legal documents in Irish (Semester 2) (https://sites.google.com/site/irishlegaldeeds/). He also pursues an active research and publication interest in Irish language and literature, from medieval to modern times. He is committed to local history studies, and to the promotion of the Gaeltacht areas as unique centres of Irish culture; Pádraig edits and publishes two journals that reflect these interests: Ossory Laois and Leinster, and An Linn Bhuí: Iris Ghaeltacht na nDéise.
