My research focuses primarily on phonology, as a subfield of cognitive science, and specifically on the nature of phonological representations. Questions in phonetics-phonology, phonology-morphology addressed recently include:

• Is the temporal dimension of linguistic form implementational, 'low-level mechanics' of speech articulation or is it deeply grammatical? What are cognitively and biologically plausible ways of threading a notion of time in the representations? (A Grammar of Gestural Coordination)

• What is the proper way to characterize non-concatenative morphology and phonology? Do languages with non-concatenative morphology require special phonological representations? (On the Proper Characterization of Non-Concatenative Languages, Eliminating Long Distance Consonantal Spreading, The Initial State and Verbal Stems in Classical Arabic)

• Are there constraints on phonological assimilations grounded in the articulatory system? (The Articulatory Basis of Locality in Phonology) Recent work on this topic uses the electromagnetometer and ultrasound systems at Haskins Laboratories to study the articulatory correlates of vowel harmony (supported by NIH).

• Description and analysis of the phonology and morphology of Modern Greek dialects, in collaboration with Angeliki Ralli, at the University of Patras, Greece. Work has focused on two dialectal varieties of Lesvos. (Morphosyntactic Features and Paradigmatic Uniformity in two Dialects of Lesvos)
