Personal profile
Research interests
I investigate speech production and perception, and phonological organization in human language. We use MRI, electromagnetic articulography (EMA), ultrasound, eye-tracking, and other technologies to investigate how speech sounds are made and processed, and how language is acquired and used by adults, children, second language learners, and disordered populations.
Research student supervision
Applications from students interested in higher degree research at Macquarie, or through IDEALAB are welcomed. We are happy to consider dissertation proposals which address key issues in phonetics or phonology with a strong theoretical motivation and an elaborated experimental component.
