Her main areas of interest are multilingualism (especially at the level of mental lexicon and syntax) and applied psycholinguistics (modalities, learner profiles and affectivity). As a teacher trainer she lectures on research methods in second language acquisition and TEFL projects. Her major concern is the role of action research in teacher development. Prof. Gabryś-Barker has published over a hundred articles nationally as well as internationally and a book Aspects of multilingual storage, processing and retrieval, Katowice: University of Silesia Press, 2005 and Reflectivity in pre-service teacher education which came out in 2012.  She has edited nine volumes, among others a volume Morphosyntactic Issues in Second Language Acquisition (Multilingual Matters, 2008), Topics in Applied Psycholinguistics (University of Silesia Press, 2015) and co-edited The Affective Dimension in Second Language Acquisition (Multilingual Matters, 2013).

Dagmara Gałajda received her Ph.D. degree in linguistics from the University of Silesia, where she works as assistant professor. The research area of her doctoral thesis concentrated on willingness to communicate (WTC) in L1 and L2 and on other related communication variables like communication apprehension (CA) and self-perceived communicative competence. Apart from communication studies, her research interests focus on teacher's action zone in facilitating group dynamics, affect in language learning, individual learner differences in SLA / FLL and reflective teaching.
