My research area is sociophonetics - I work in phonetics & phonology (and the interface between the two) but always have at least one eye firmly fixed on variation in spoken language. This means I work at the intersections between phonetics & phonology and sociolinguistics, (particularly language variation and change). I am interested in how language varies according to a whole range of geographical and social dimensions in both large and small speech communities, and also how that variation can be modelled in a phonological theory. Two broad questions that keep me occupied are: (i) what is 'a phonology' and what information is stored there? and (ii) how can phonological theory benefit from the insights of variationist sociolinguistics?
