Research interests
My research interests at Macquarie centre on auditory processing disorders in children. The questions that need answering are:
1. How can we determine how much of the listening difficulty experienced by a child is caused by deficits in each of auditory processing, speech sound identification, cognition, and language deficits?
2. Within each of these broad areas, but particularly within the auditory processing area, what is the nature of the specific underlying defict(s)?
3. How can deficits in auditory processing be remediated, and what else changes as a result?
Research student supervision
As I plan to retire in late 2026, I am not seeking any further PhD research students.
