My earlier work focused on phonetic variation in Southern British English and social aspects of pronunciation. I explored how popular perceptions of accents created the myth of the emergence of Estuary English carried out fieldwork, which lent no support to claims regarding the existence of a homogeneous accent variety in the Home Counties. My continued interest in English speech led to a co-edited volume English Pronunciation Models: A Changing Scene, which deals a range of issues in the integration of pronunciation into English as L2 curricula, as well as educational, and psychological aspects of communicating in a (non)native variety and the problems foreign language users face when exposed to language variation.

More recently I have been working at the boundaries of disciplines, combining instrumental phonetics methods with exploration of socio-historical perceptions of accents and diachronic developments in English speech, such as lenition of stops and change in Voice Onset Time. Currently, I am involved in a number of projects: investigating acoustic correlates of glottalization in Southern British English, an accelerometric study of nasal coarticulation in Polish vowels,  the exploration of native and adoptive variants of Received Pronunciation in the 1930s, and the history of experimental phonetics in Poland.
