Plenary Speakers


Tobias BernaischTobias Bernaisch is Senior Lecturer for English linguistics in the Department of English at Justus Liebig University Giessen, Germany. His research focuses on and combines concepts and methods from world Englishes, corpus linguistics and genderlectal variation. He has published the first comprehensive corpus-linguistic account of Sri Lankan English and dedicates himself to modelling linguistic epicentres empirically – particularly in South Asia, but also in other parts of the Anglophone world such as Australia and New Zealand. For this purpose, his colleagues and he have compiled a number of large-scale corpus-linguistic resources such as the Sri Lankan component of the International Corpus of English or the South Asian Varieties of English (SAVE) corpus and its 2020 update. These resources habitually form the empirical bases for his work on the lexicogrammar and the pragmatics of varieties of English, which relies on multifactorial statistical modelling techniques. From a sociolinguistic angle, his research explores the role of genderlectal variation in world Englishes, but also in the history of the English language.
