Dr Matt Petoe is a biomedical engineer with a keen interest in human perception, neuroscience and clinical research. Prior to joining the Bionics Institute in November 2012 he was involved in a number of projects aimed at improving clinical outcomes in different patient groups. Working with the Mater Mothers’ Hospital and The Hear and Say Centre in Brisbane, Matt’s PhD research investigated methods of improving the auditory brainstem response test – a diagnostic test used for neonatal hearing screening and assessing neuropathic hearing loss. His work improved the speed and robustness of the test, and received recognition in awarded patents and the formation of a hearing-screening technology company.

Following his PhD, he took up a Stroke Foundation Research Fellowship (Auckland City Hospital, New Zealand) and oversaw the recruitment and assessment of stroke patients receiving a novel therapy for upper limb impairment. This successful clinical trial demonstrated that ‘priming’ the brain before physiotherapy sessions promotes faster recovery of upper limb function following stroke.

Bringing these prior experiences together, Matt realised an ambition to work at the Bionics Institute and develop medical device technologies. He is currently working within the Bionic Vision research team and integrating a video camera and vision processing with the 24-channel prototype bionic eye implanted in three patients in 2012. He is a chief investigator on a recently awarded NHMRC project grant (2015 - 2017) to trial the safety and efficacy of the next generation, wide-view bionic eye.
