I'm a postdoctoral associate at the Department of Linguistics and Philosophy at MIT (the linguistics part). Starting July 2025, I will be a visiting assistant professor in linguistics at the Program in Linguistics at Brown University. I got a PhD in linguistics at MIT in 2023, and my dissertation Lessons from CP in Passamaquoddy and beyond examines issues in the morphosyntax of CP in Passamaquoddy-Wolastoqey (Eastern Algonquian), looking at how the presence/absence of CP contributes to the syntactic and semantic properties of different clause types, as well as the unusual phi agreement behavior C displays across the family and its consequences for the theory and typology of agreement phenomena.
I am a syntactician whose primary theoretical interests lie at the interfaces:
How do different modules of the grammar (syntax, semantics, morphology, phonology) work together to generate a typology of possible grammatical phenomena?
How do different kinds of representations get translated from one module to another—what kind of information gets preserved or lost?
How can we diagnose which module holds the "right answer" to solve a particular empirical puzzle?
How can a proper understanding of the interfaces allow for simpler, more minimal theories of each module?
I am also a fieldworker, and much of my work involves working with speakers of Passamaquoddy-Wolastoqey to establish correct descriptive generalizations and understand their broader theoretical and typological consequences.
More specifically, I have worked on the syntax-semantics of clausal embedding and coordination, the syntax of cross-clausal dependencies, the ordering of postsyntactic operations in Distributed Morphology, the morphosyntax of agreement, the morphological reflexes of multiple agreement and multiple case marking, the structure of phi features, the Algonquian inverse, the syntax-semantics of modals, the semantics and pragmatics of future talk, the interaction between evidentiality and the dynamics of assertion, and ellipsis.
I was born and raised in Dallas, Texas. Outside of linguistics, I enjoy cooking, eating, board games, tabletop RPGs, social deception games, and petting cats. In a past life I was an active amateur violinist.
