My research interests are in bilingualism, particularly code-switching and I recently organised an interdisciplinary workshop on code-switching, held in Cambridge on 3-4th October 2016. This led to the establishment of a code-switching reading group which met regularly in the year 2016-2017 and will continue in 2017-2018. I have recently completed a book about Welsh-English code-switching to be published by John Benjamins. With a research team at Bangor University we collected bilingual conversations from three groups of bilinguals: Welsh-English, Spanish-English and Welsh-Spanish. The conversations were transcribed and are made available in the public domain ( Data from the corpora have been used by my collaborators and myself to evaluate competing linguistic theories of code-switching (e.g. Herring et al 2010), to compare code-switching patterns in three bilingual communities (Carter et al 2011), challenge influential views of the boundary between code-switching and borrowing (Stammers & Deuchar 2012) and to establish the key extralinguistic factors influencing the production of code-switching (Deuchar et al forthcoming). Current work focuses on the choice of the matrix language in Spanish-English code-switching and how this is related to the structure of mixed nominal constructions.
