He is a Professor in the Department of Brain and Cognitive Sciences at the Massachusetts Institute of Technology, where he directs MIT's Computational Psycholinguistics Laboratory. Before coming to MIT, he was faculty in the Department of Linguistics at UC San Diego. He is serving as Chair of the MIT Faculty from 2025–2027.
Background
His research focuses on theoretical and applied questions in the processing and acquisition of natural language. Specifically, he is interested in how a fixed set of knowledge and resources can be used to manage uncertainty over a potentially unbounded set of possible signals and meanings. To address these questions, he combines computational modeling, psycholinguistic experimentation, and analysis of large naturalistic language datasets.
