Biography
Distinguished Professor Katherine Demuth is the founding Director of the Child Language Lab and the Director of the Centre for Language Sciences (CLaS) at Macquarie University. Demuth's research focuses on Language Acquisition, including studies of both perception and production. She is especially interested in the development of phonological, morphological and syntactic representations, in both typically developing and language-impaired children and L2 learners. Much of her work is crosslinguistic, using insights from the structure of different languages to better understand the mechanisms underlying the process of language acquisition. She was awarded an ARC Laureate Fellowship 2013 for research on child language acquisition, one of 17 awards for science in Australia.
