Miquel Simonet is a laboratory phonologist and who specializes in the phonology of the Ibero-Romance languages. As a laboratory phonologist, Miquel studies the sound patterns of languages: how they are manifested in production and perception, how they are processed, and how they develop and vary. One of his principal areas of expertise is bilingualism, in particular, the phonetics, phonology, and psycholinguistics of bilingualism and second language learning. The goal of such research is to understand the nature of phonological representations in the bilingual mind and the patterns that characterize the phonetic behavior (pronunciation, perception, lexical access) of bilinguals. Another area of interest is phonological variation and change. His interests in the broader field of second language acquisition has been growing in the last few years.

Miquel's publications have appeared in journals such as the Journal of Phonetics, the Journal of the International Phonetic Association, Language and Speech, Second Language Research, the International Journal of Bilingualism, Phonetica, Laboratory Phonology, Linguistics, Probus, Linguistic Approaches to Bilingualism, Languages, Hispania, and Studies in Hispanic and Lusophone Linguistics. He currently serves as Associate Editor for the journal Applied Psycholinguistics, and is a member of the editorial or advisory boards of the journals Second Language Research and Laboratory Phonology. Miquel is a member of the International Phonetic Association and of the Association for Laboratory Phonology.

At the University of Arizona, Miquel currently serves as the Director of Graduate Studies in the Department of Spanish and Portuguese. Additionally, he is a member of the faculty in the graduate interdisciplinary program in Second Language Acquisition and Teaching (SLAT GIDP), where he chairs the Cognitive Dimensions of SLA track, and the graduate interdisciplinary program in Cognitive Science (CogSci GIDP). Miquel graduated with PhD in Romance Linguistics from the University of Illinois at Urbana-Champaign in 2008.
