Prof. Roger P Levy

Roger Levy asks theoretical and applied questions about the processing and acquisition of natural language, with a focus on how linguistic communication resolves uncertainty over a potentially unbounded set of possible signals and meanings. His research sits in cognitive science at the intersection of artificial intelligence, cognitive psychology, and linguistics. Levy’s research program investigates how knowledge and cognitive resources are deployed to manage uncertainty and derive meaning to support language comprehension and production, the character of representations in the brain that supports these operations, and how the relevant knowledge is acquired. Combining computational modeling of large data sets with psycholinguistic experimentation, Levy’s work furthers our understanding of the cognitive underpinning of language processing, and helps us design models and algorithms that will allow machines to process human language.
