Zubizarreta was born and raised in Asunción, Paraguay. She obtained her Maîtrise in General Linguistics from Paris 8 University in 1978 and her PhD in Linguistics from the Massachusetts Institute of Technology in 1982, with a dissertation entitled On the Relationship of the Lexicon to Syntax.[2] She held various academic positions before arriving at the University of Southern California (USC), where she held a position from 1988 until her retirement.[3]
Zubizarreta has conducted her research within the framework of generative linguistics. More precisely, she is interested in linguistic theory as a model of mental competence and performance. Her approach is comparative and considers interface issues ranging from the relation between the lexicon and syntax (Zubizarreta 1987) to the prosody and syntax of focus (Zubizarreta 1998).[5]
Zubizarreta has conducted empirical research into issues dealing with second language acquisition, focusing on the mental grammar of the learners as they develop interlanguage (Zubizarreta & Nava 2011). Her work has also explored person-related phenomena from a semantic perspective in different languages, including the use of person features in Paraguayan Guaraní (Zubizarreta & Pancheva 2017a, b).
Honors
A workshop, entitled Person and Perspective, and a related Festschrift were organized in her honor in 2019.[6] The Festschrift, published by Cambridge University Press, is entitled Exploring Interfaces.[7]
