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 explores the psycholinguistic aspects of bi- and multilingualism, particularly cross-linguistic influence in L2/L3 acquisition and processing. Currently, I am investigating how child and adult L2/L3 learners acquire and process morphosyntactic features such as gender, case, and number. Additionally, I am examining the interface between grammar and cognition, including how grammatical processing relates to personality and gender stereotypes, an emerging area in my research.
