My research focuses on the formal syntax, morphology, and semantics of spatiotemporal grammatical phenomena cross-linguistically (especially in endangered languages) and their interactions; specifically, tense, aspect, mood/modality; prepositional notions; and nominals. I am particularly interested in what the data from these areas can tell us about the nature of the interfaces among syntax, morphology, and semantics.
I am intrigued by the interactions between aspect and nominals/nominalization cross-linguistically, and in nominal functional structure in general. Underlyingly, I am interested in the contributions of roots and functional structure to meaning and the flexibility of categories (see my Lingua article, e.g.).
From a theoretical standpoint, I seek to test the hypothesis that morphological structure and processes are isomorphic with syntactic structure and processes. One branch of my current research focuses on the implications of so-called “multiple” or “distributed” exponence for the Distributed Morphology framework (see e.g. my article with Megan Stone in Morphology).
My published work has focused on nominal predication in Scottish Gaelic; on aspect in Scottish Gaelic, Classical Greek, Turkish, and English; on modality in Cherokee; on prepositions in American English and Scottish English; and on the syntax-semantics interface.
In the summer of 2013 I spent time on the Isle of Skye in Scotland, collecting Scottish Gaelic, Scottish English, and Doric (Northeast Scots) data.
I also have research interests in the following areas: theoretical and experimental morphology; cognitive science; lexical semantics and event structure; language description, documentation, and revitalization; psycholinguistics and lexical access; Scottish Gaelic (an endangered language); Ancient Greek; American Sign Language.
I was Research Associate and contributor to Andrew Carnie’s Arizona Scottish Gaelic Syntax Project.
I’ve also been involved with the University of Arizona’s Psycholinguistics and Computational Linguistics Lab on a project on lexical access in Semitic.
