After obtaining a degree in Italian Philology, Russian Philology and French Linguistics from the University of Basel, she was assistant in French Linguistics and in General Linguistics at the same university. In Basel, she worked on linguistic biographies of multilingual speakers (e.g. the volume Leben mit mehreren Sprachen. Sprachbiographien / Vivre avec plusieurs langues. Biographies langagières, Bern, Peter Lang, 2004, co-edited with Rita Franceschini), on the interactive construction of scientific discourse in a multilingual environment, and obtained, in 2002, a PhD in French Linguistics (Le traitement de problèmes lexicaux lors de discussions scientifiques en situation plurilingue. Procédés interactionnels et effets sur le développement du savoir, Bern, Peter Lang, 2005). After a period at the University of Turin, where she researched the conditional and discourse markers of spoken language, the University of Basel granted her, in 2010, the habilitation to teach Romance Linguistics. At the Institute of Italian Studies of the University of Lugano, she teaches Linguistics and Pragmatics for the Bachelor and Master in Italian Language, Literature and Civilization. She has taken part in a research project on "Modality in Argumentation. A semantic-argumentative study of predictions in Italian economic-financial newspapers" (a project of the Swiss National Science Foundation, No. 100012-120740, 2008-2011). She has co-directed the Swiss National Science Foundation project No. 141350 "From perception to inference. Evidential, argumentative and textual aspects of perception predicates in Italian" (USI, 2012-2015). From 2012 to 2016 she was chair of the Swiss Association for Applied Linguistics.
