Kate Burridge is Professor of Linguistics in the School of Languages, Cultures and Linguistics, Monash University, and a fellow of the Australian Academy of the Humanities. Her main areas of research are: grammatical change in Germanic languages, the Pennsylvania German spoken by Amish/Mennonite communities in North America, the notion of linguistic taboo and the structure and history of English. She is a regular presenter of language segments on radio and has appeared as a panelist on ABC TV's 'Can We Help?'. Tonya N. Stebbins has had a distinguished academic career as a lecturer, researcher and administrator. Among the subjects Dr Stebbins has taught for many years at the tertiary level are English grammar and subjects on the sociology of language and on bilingualism and language acquisition. Her online grammar learning tool, Grammarpedia (www.languagetools.info/grammarpedia), was developed to support a blended learning approach to English grammar and has been used in tertiary courses on English grammar since 2008. Between 2010 and 2012, Dr Stebbins led the Centre for Research on Language Diversity (CRLD) at La Trobe University. CRLD, formerly known as the Research Centre for Linguistic Typology, is one of Australia's leading institutes for grammatical research and language documentation for little known minority languages. In March 2012, Dr Stebbins commenced a 12-month leave of absence from La Trobe University to establish Languagewise, a consultancy specialising in innovative strategies for language development, and to make a more direct contribution to the support of language development and language diversity in the community.
