Máire Ní Chiosáin studied for her BA in Linguistics and Irish at UCD, spent a year at the Department of Linguistics at the University of Trondheim, and completed her PhD dissertation entitled Topics in the Phonology of Irish at the University of Massachusetts, Amherst. She returned to a position in the then Department of Linguistics in UCD, and is now part of the School of Languages, Cultures & Linguistics. Her research has focused, for the most part, on Modern Irish, addressing a variety of theoretical issues including, most recently, the representation of secondary articulations palatalisation and velarisation in Irish, the perception of palatalisation, short vowel phonemes and consonant-vowel interaction and syllabification. Her work in these areas has been largely collaborative and has been supported by research grants (including a National Science Foundation (US) grant 2004-17 for an ultrasound study of Irish palatalization and velarisation with Jaye Padgett, Grant McGuire (UC Santa Cruz) and Ryan Bennett (Yale University); IRC Ulysses grants 2013, 2010 for research on the production and perception of Irish initial consonant mutations with Pauline Welby (LPL, CNRS-Université de Provence, Brian Ó Raghallaigh (DCU)). Other funded research includes recent work on the short vowels in Irish and Scottish Gaelic with Pavel Iosad (University of Edinburgh) and work on the perception of palatalisation in Irish and Russian with Jaye Padgett (UCSC). Research supervision has included theses on Irish Phonology, Irish English phonology and the Sociolinguistics of Irish (Language Attitudes and varieties of Irish in Irish-medium schools). Current teaching includes modules on Phonology, Phonetics and Minority and Endangered Languages.
