Dr Tomoko Hyakumura, Research Fellow

Tomoko is a postdoctoral researcher at Bionics Institute. Prior to joining Bionics Institute, she completed her PhD at the University of Melbourne investigating the potential of regenerating the auditory nerve using stem cells.

She joined Bionics Institute in 2018, taking part in the study of vagus nerve stimulation for treatment of inflammatory bowel disease.

Dr Hyakumura gained further preclinical research experience studying a range of unique neural signals from both the central and peripheral nervous system utilising novel electrode coating materials in collaboration with researchers at University of NSW.

Currently, she is involved in a number of different pre-clinical research projects including stimulation and recording from the cochlea and pelvic nerve, and vagus nerve stimulation for treatment of diabetes.
