Hedde Zeijlstra is Professor of English Linguistics and Theory of Grammar at the University of Göttingen, and previously held positions at the universities of Amsterdam and Tübingen, and at MIT. He is an expert on the syntax-semantics interface, and has worked intensively on negation and negative dependencies, including negative concord, negative polarity sensitivity, and positive polarity sensitivity. He has also worked agreement phenomena, as well as tense, modality, and word order constraints. He is the co-author, with Olaf Koeneman, of Introducing Syntax (CUP, 2017).
