I'm a researcher in psycholinguistics. My research focuses on how complex words are learned, mentally represented, and processed in real-time by both native and non-native speakers.
The main theoretical topics I address with my work are (a) the development and comparison of formal and computational models of the mental lexicon, and (b) the role of age of second language acquisition as a source of contrasts between native and non-native speakers.


I work as a lecturer and postdoctoral researcher at the
Potsdam Research Institute for Multilingualism of the University of Potsdam, Germany.
