  • Abbey Sawyer
    Abbey Sawyer joined the Abilities Research Centr in 2022 as a Post-Doctoral Research Fellow. Her current research focusses on early feasibility work of brain-computer interfaces to optimize communication in people with neurological conditions, in particular, amyotrophic lateral sclerosis (ALS), spinal cord injury, stroke and multiple sclerosis. Abbey passion for this field of research stems from watching her grandfather live with severe paralysis from multiple sclerosis during her early years. It is her hope that in the not too distant future, people with severe paralysis will be able to communicate and engage with their environment in the most meaningful way for them to optimize quality of life. Mostly recently, Abbey worked as a Post-Doctoral Trial Manager at the University of Melbourne leading research in respiratory care and sleep for people with ALS and other neurological conditions.

    Abbey’s background is in exercise testing and training in people with chronic pulmonary conditions. Abbey holds a PhD (Exercise, Sports and Rehabilitation Science) from Curtin University in Perth, Australia and has extensive clinical experience as an acute care and outpatient-based physiotherapist (Bachelor of Physiotherapy, First Class Honors) in Australia.
