Research

Prasath has a primary interest in rehabilitation of individuals with pain and physical disability. Prasath completed his doctoral studies in 2012 on postural balance in lower limb amputations. He has since completed two postdoctoral fellowships, first at Brunel University, London (one year), followed by another at School of Physiotherapy, University of Otago (three years) where he was involved in projects investigating gait and balance, with an application to people with pain and disability. In March 2017, he accepted an academic position at the School of Physiotherapy to develop and strengthen balance research across lifespan.

His current investigations and research interests:

Postural control, functional balance and sensory-motor re-organisation across the lifespan in individuals with physical disability
Supporting people to live well with Parkinson's disease. This includes supporting Physiotherapists role as part of this.
