I am an Associate Teaching Professor at the University of California San Diego. My major research interests center around language variation and change, Spanish in contact, bilingualism, Spanish as a heritage language, language acquisition, and Spanish phonology. I am especially interested in the Spanish spoken around the US-Mexican border and through variationist methodology differentiating contact-induced change from language-internal variation by comparing the Spanish of monolingual speakers in Sonora, Mexico to the Southern Arizona bilingual Spanish of speakers who come from families from Sonora.
