Hi! I am an Assistant Professor and Head of the Cognitive and Affective Approaches to Language Lab at Adam Mickiewicz University in Poznań, Poland.

My research focuses on psycholinguistic aspects of bi- and multilingualism, with particular emphasis on cross-linguistic influence in L2 and L3 acquisition and processing. I am especially interested in how child and adult L2/L3 learners acquire and process morphosyntactic features such as grammatical gender, case, and number. In addition, I examine the interface between grammar and cognition, including how grammatical processing relates to personality traits and gender stereotypes—an emerging strand of my research.
