Researcher biography
Joseph is the Director of the Hearing Research Unit for Children, leading three research teams investigating (1) middle ear assessments in neonates, infants, (2) hearing screening and assessment of school-age children, and (3) assessment of auditory function of adults and children using electrophysiologic measures including otoacoustic emissions, auditory evoked potentials and wideband acoustic immittance. He is an associate editor of the International Journal of Audiology, and editorial board member of two international journals: International editorial member of the Journal of the American Academy of Audiology and Communication Disorders Quarterly (USA). As a world leader in the field of middle ear assessment for children, Joseph's research has a significant impact on the policy and clinical practice of paediatric diagnostic audiology at both national and international levels. To date, he has published over 128 publications in national and international peer-reviewed journals.
