I currently hold a joint position in the University of New Mexico’s Department of Spanish & Portuguese and Department of Linguistics. My two primary areas of research are: 1) Spanish in the United States and how it is shaped by bilingualism and language contact, and 2) the acquisition of Spanish during childhood (among both monolingual and bilingual children). One common theme in my research is to explore how functionality influences the trajectory of language change and development. Much of my research has focused on Spanish spoken in New York City, where I was born and raised. Currently, I am building two corpora of spoken Spanish, one consisting of narratives produced by monolingual children in Mexico and the other of narratives produced by the (bilingual) children of migrant workers in Washington and Montana. These corpora are being used to examine the development of linguistic structures, such as pronominal expression.
