My research interests are as follows:
- Syntactic theory
- Language universals and the range of cross-linguistic variation
- Heritage languages and their bearing on linguistic theory
I work on various syntactic topics including long-distance dependencies, verb phrase structure, ergativity, and verb-initial orders I have done primary work on a variety of languages: languages of the Caucasus, Austronesian, and Mayan languages. My research also includes structural properties of language spoken by unbalanced bilinguals: what is now known as heritage language.
