Senior Research Fellow

Janet Pierrehumbert

  • I am Professor of Language Modelling in the Oxford e-Research Centre and the Department of Engineering Science.

  • I have an interdisciplinary background in linguistics, mathematics, electrical engineering and computer science.

  • I am currently working on the relationship between the dynamics of language and the structure of linguistic systems.

  • I studied at Harvard and MIT and then worked in the Linguistics and AI Research Department of AT&T Bell Laboratories and the Linguistics faculty at Northwestern University before coming to Oxford in 2015.

Research

My current research focuses on the relationship between the dynamics of language — in acquisition, processing, or historical change — and the structure of linguistic systems. It combines experiments, statistical analyses of large corpora, and computational simulations of linguistic communities. In collaboration with colleagues at the New Zealand Institute of Language Brain and Behaviour, I am investigating the cognitive and social mechanisms that make it possible for people to have such large vocabularies, continually creating and adopting new words as they adapt to new situations. This project builds on analogies between linguistic evolution and biological evolution, and it uses crowd-sourced data in the form of on-line word games.

I am one of the founding members of the Association for Laboratory Phonology, an interdisciplinary research organisation that promotes the scientific study of all aspects of language sound structure. I am a Fellow of the American Academy of Arts and Sciences, the Linguistic Society of America, and the Cognitive Science Society. I was elected as a member of the National Academy of Sciences in 2019.

How do language dynamics – in acquisition, processing or historical change – relate to the structure of linguistic systems? How do social and cognitive factors interact in shaping human languages? I explore these questions using experiments, statistical analyses of large corpora, and computational modelling, including new neural network approaches to learning and prediction.
