The majority of my scholarship has focused on adults’ ability to establish and to use lexical representations in a second language. The involvement of the lexicon (narrowly defined here as a set of mappings between meanings and phonological forms) is central to my work: Unlike research focused primarily on speech production and perception in their own right, I investigate these phenomena primarily as they function in the service of distinguishing minimally contrastive lexical items. In an effort to better understand the nature of learners’ lexical-phonological structure, I am particularly interested in the sources of information that contribute to the phonological content of lexical representations—that is, the role that various types of input play in L2 acquisition.
