BA Hons (Univ Sydney), PhD (Monash University)
 
Professorial Research Fellow and Senior Research Advisor, Bionics Institute

Professor Dexter Irvine’s original training was in experimental psychology, but as a graduate student he moved into the field of auditory neuroscience. After post-doctoral training at the University of Western Australia and the University of California at Irvine, he joined what is now the School of Psychology and Psychiatry at Monash University. His research has been focused on neural mechanisms of hearing and sound localization at various levels of the auditory pathway and on auditory system plasticity. He is currently an Emeritus Professor at Monash University and has a part-time appointment at the Bionics Institute.

Professor Irvine has published a monograph on auditory brainstem processing, a co-edited book on auditory spectral processing, and approximately 110 peer-reviewed publications and book chapters. He has received continuous funding from the National Health and Medical Research Council since 1986, and is a Fellow of the Academy of Social Sciences in Australia.

Research fields of interest
