Paul Kerswill is Professor at the Department of Language and Linguisitc Science at the University of York. His research is in language variation and change, with an emphasis on phonetic but also grammatical and discourse variation. It is largely focused on dialect contact – the long-term linguistic consequences that ensue when speakers of different accents or dialects come together through migration and mobility.
A consequence of dialect contact is dialect levelling – the overall reduction in linguistic diversity across a dialect area. He worked on a speech community in which there has been 'extreme' levelling - the New Town of Milton Keynes. With colleagues at Queen Mary, University of London, he has also worked extensively on Multicultural London English, a new 'contact variety' which has emerged in London's East End and elsewhere in the capital. This has led to his growing interest in new youth language varieties, particularly in Northern Europe, where he maintain contacts with scholars in several countries.
Sali A. Tagliamonte is Canada Research Chair in Language Variation and Change and a Full Professor in the Linguistics Department at the University of Toronto, Canada.

Her research has been funded by agencies in Canada, the US and UK. Her most recent research is the Ontario Dialects Project, which focuses on cross-community and apparent time comparisons in corpora of spoken vernacular dialects to explore linguistic change.
