My research focuses on issues in the phonetics and phonology of different varieties of Spanish from a theoretical perspective, employing laboratory methods to validate my claims. I investigate topics in phonological structure at different levels of Spanish prosody: syllable structure, stress, intonation, rhythm, and voice quality. My most recent publications are based on the intonational structure of questions and statements in varieties of Spanish spoken in northern, central, and southern Spain, adhering to theoretical principles in autosegmental prosodic structure. I am also exploring topics related to sociophonetic variation in Manchego and Andalusian Spanish (in the latter project I collaborate with Lorenzo García-Amaya of RLL). At Michigan I have begun to research issues relating to rhythm in Spanish, and second language rhythm in particular. Specifically, I have worked on rhythm in Spanish in contact with English (in the United States) and with Afrikaans (in Argentina). The latter project is based on a collaboration with Andries Coetzee (Department of Linguistics) and Lorenzo García-Amaya.
My latest journal articles are published in Laboratory Phonology, Language and Speech, Journal of the International Phonetic Association, Probus, and Linguistic Approaches to Bilingualism. Currently, I am co-editing a volume entitled Interdisciplinary Approaches to Intonational Grammar in Ibero-Romance, published by John Benjamins Publishing Company (co-editors: Meghan Armstrong of University of Massachusetts & Maria del Mar Vanrell of Freie Universität Berlin). Our target publication date is Fall 2015.
