Ida Mauko is a PhD student at the University of Helsinki, where she has also completed her Master’s degree in English Philology. Specializing in Sociolinguistics, she is interested in the way English is used globally, both by non-native speakers and speakers of English as a Second Language (ESL), as well as how these speakers build their linguistic identity as English speakers. Having completed her Master’s thesis on the topic of the native English speaker concept and the conflicts which arise from trying to define it, she is currently involved in postgraduate research with a focus on linguistic identity and English as a Lingua Franca in the academia. More specifically, the international collaborative project in which she is participating at present explores how language policies at the University of Helsinki relate to practices and everyday attitudes towards language use, especially with regard to English used by international students and staff. Ms Mauko has, in addition, completed her pedagogical education through the University’s English-medium subject teacher education programme (STEP), and also holds a minor degree in Intercultural Encounters, all of which has brought her very valuable experience in diverse communication and teaching environments. She has worked as a translator, proof-reader, substitute teacher and as part of IELTS test personnel, thus working not only with written language, but also with people of various ages and backgrounds. In the future, she would like to focus on research and on developing her teaching skills in higher education.
