As a laboratory phonologist, I study the sound patterns of human languages. I am interested in topics such as sound category formation, development, and change. My primary area of research is bilingualism—in particular, the phonetics, phonology, and psycholinguistics of bilingualism and second language learning. My most recent research is concerned with understanding the nature of phonological representations in the bilingual mind. I use experimental approaches to examine speech production and perception, phonological encoding, and spoken word recognition in bilinguals and second language learners. My work has appeared in journals such as Journal of Phonetics, Language and Speech, Second Language Research, International Journal of Bilingualism, Phonetica, Linguistics, and others. I am currently serving the profession as Associate Editor of Applied Psycholinguistics (Cambridge University Press). At the University of Arizona, I teach in the Hispanic Linguistics program and currently serve as the Director of Graduate Studies in the Department of Spanish and Portuguese. In addition, I am a member of the faculty in the graduate interdisciplinary program in Second Language Acquisition and Teaching (where I serve as chair of the Cognitive Dimensions track), and the graduate interdisciplinary program in Cognitive Science. I have supervised doctoral-level research in both the Hispanic Linguistics and the SLAT graduate programs, and I welcome enquiries to conduct research under my supervision from students considering applying to such programs.
