Peter Grishin is joining Brown Linguistics as a Visiting Assistant Professor, having most recently been a Postdoctoral Associate at MIT after earning a PhD there in 2023 with a dissertation titled “Lessons from CP in Passamaquoddy and beyond”. Peter's broad research interests lie in formal syntax and its interfaces with morphology and semantics, aiming to understand how complex linguistic systems arise from the interaction of distinct modules of the grammar. Specific topics of interest include the syntax and semantics of clause size in clausal complementation and coordination, constraints on cross-clausal dependencies, the morphosyntax of phi agreement, and the ordering of postsyntactic/morphological operations. Peter is also an avid fieldworker, working with speakers of Passamaquoddy-Wolastoqey, an Eastern Algonquian language spoken in Maine and New Brunswick, to better understand the language on both descriptive and theoretical levels. This fall he will be teaching LING 0100 Introduction to Linguistics and LING 1310 Introduction to Syntax.
