Research interests

My research interests include psycholinguistics, multilingual processing, language contact, sociolinguistics, heritage and endangered languages, particularly Campidanese Sardinian. 

I am a member at the Second Language Acquisition Lab. My research there focuses on how active use influences bilingual performances and on methods of measuring dominance, as well as the interplay between dominance and heritage languages. I am currently exploring pronoun resolution strategies in multilingual speakers.

Comparing dominance measures in bilingual speakers of typologically different languages

This study aims to contribute to a better understanding of dominance in typologically different languages, such as Turkish and English. Developing robust measures of dominance is especially important and challenging for this population, since most methods to measure dominance rely on syntax or grammatical structures.

Evidentiality and language contact: A case study of Turkish children in Berlin

This MA dissertation looked at the changes that Turkish evidentiality is undergoing in bilingual children living in Berlin due to contact with German. Previous studies (Herkenrath 2016) have found that in Turkish/German bilingualism the evidential suffix has disappeared, therefore we hypothesize that the Turkish evidential mark may have undergone attrition.

Does Italian dominance affect Sardinian phonology? A case study of Southern Campidanese

This study looks at whether a peculiar phonological process of Campidanese (intervocalic lenition at the word boundary) is affected by Italian. In particular, I looked at whether speakers’ dominance affects this process
