Professor Lorraine Leeson has been at the forefront of building the discipline of applied/theoretical sign linguistics in Ireland. Her work is multidisciplinary in nature, influenced by her background in Deaf studies, gender studies and linguistics. She has published widely on aspects of the linguistics and applied linguistics of sign languages, with a specific interest in Irish Sign Language ISL) and sign language interpreting, taking a cognitive-functional perspective. Her doctoral work was the first to examine aspects of the morphosyntax ISL, and subsequent to this, she led work on the Signs of Ireland corpus, one of the first digital, annotated corpora of an indigenous sign language in the world. She also led work on the Sign Language Acquisiton Corpus, which focuses on hearing adult learners of ISL as a second language. Lorraine is a practicing interpreter: She was a member of the first cohort of formally trained ISL/English Interpreters and has worked as an interpreter nationally and internationally. She is a Fellow of Trinity College Dublin. In 2014, Lorraine was awarded honorary membership of the Irish Translators and Interpreters Association for her work on Irish Sign Language, which has informed policy underpinning the Irish Sign Language Recognition Act (2017). Lorraine is Co-Chair of the European Forum of Sign Language Interpreters Committee of Experts. She has been involved in many European Commission and European Centre for Modern Languages projects, including two European Language Label award winning projects. Her most recent book is “Interpreting and the Politics of Recognition” (Routledge), co-edited with Christopher Stone.
