François Grosjean is a Professor Emeritus and former Director of the Language and Speech Processing Laboratory at the University of Neuchâtel (Switzerland). His specialty is psycholinguistics and his domains of interest are the perception, comprehension and production of language, be it speech or sign language, in monolinguals and bilinguals. He also has interests in biculturalism, applied linguistics, aphasia, sign language, and natural language processing. He is better known for his work on bilingualism in which he has investigated the holistic view of bilingualism, language mode, the complementarity principle, and the processing of code-switching and borrowing. In one of his most-cited papers, Grosjean argues that hearing-impaired children have the right to grow up bilingual, learning two languages—namely, sign language and oral language.
