Dr Thushara Perera began working at the Bionics Institute in 2012 and has since been involved in the Bionic Vision and Neurobionics research areas. He was part of the team that designed, manufactured and implanted a state-of-the-art bionic eye in Australia’s first human clinical trial. Thushara helped develop the Institute’s bionic eye software platform allowing clinicians to send information to the retinal implant. Witnessing the first bionic eye being successfully switched on and restoring rudimentary vision to a blind participant was one of the most memorable moments in Thushara’s career thus far.

At present, Thushara focusses his efforts on research to help those suffering from movement disorders such as Essential Tremor, Parkinson’s disease, and Multiple Sclerosis. Working closely with neurologists, neurosurgeons, physiotherapists and engineers, he is developing clinical tools to help optimise and guide treatment for these patients. Thushara aims to design, develop and validate precise instrumentation to measure tremor, balance, posture, rigidity and gait. These tools can be deployed in the clinic and as part of clinical trials to drive the advancement of therapies and to optimise existing treatments. These instruments are currently being used to develop a next generation brain stimulator that can automatically adjust therapy to suit patient needs.

Prior to joining the Bionics Institute, Thushara completed his PhD at La Trobe University investigating a novel technique to monitor depth of anaesthesia in young children. He also worked part time as a Biomedical Engineer at the Royal Children’s Hospital redesigning a unique audiometer to test the hearing of children who have developmental problems.
