Research Interests and Expertise

Her research focuses on the structural innovations produced by heritage speakers of Spanish and their implications for multilingual language education. Over many years, she has collected data from speakers in New York, New Jersey, Massachusetts, Florida, and California, seeking to explore cross-language interaction in the bilingual mind, how similarities and differences between the grammars are negotiated, what structures might be more or less vulnerable and under what circumstances, the role of frequency of exposure and, ultimately, the internal mechanisms underlying linguistic change.
