Australian Stuttering Research Centre

Australian Stuttering Research Centre

The Australian Stuttering Research Centre was established in 1996 with Professor Mark Onslow as its founding director. The Centre is located at the Faculty of Health Sciences, The University of Sydney. Its mission is to conduct research into the nature of stuttering, to develop and trial new stuttering treatments for adults and children, to train future researchers in the field and to support those who stutter and their families.

The Centre actively promotes excellence in stuttering treatments worldwide. It has an international focus, with international research collaborations and PhD students from many countries.

The Australian Stuttering Research Centre is supported by funding from the Faculty of Health Sciences, the National Health and Medical Research Council of Australia, the Australia Research Council and generous benefactors.

Researchers and PhD students at the Centre are speech pathologists and clinical psychologists. Speech pathologists may be called speech-language pathologists or speech-language therapists in other English speaking countries.
