The Centre has engaged in a wide range of research activity to date, working to fulfill its remit of developing the discipline of Deaf Studies in Ireland. Work includes the development of the Signs of Ireland corpus, a digital multimodal corpus annotated in ELAN. The Signs of Ireland corpus is used in teaching and learning at the Centre and was the basis for Lorraine Leeson and John Saeed's volume describing the linguistic and sociolinguistic situation of Irish Sign Language (Edinburgh University Press, 2012) and several postgraduate dissertations.
