Dr Sian Williams joined the School of Physiotherapy and Exercise Science as a Research Fellow in 2013, and is now a Senior Lecturer for the Exercise Sports and Rehabilitation Science Course. She holds a Bachelor of Science (Hons) (2007) and a PhD in Exercise and Health Science (2013), both from the University of Western Australia.

Her PhD, entitled: ‘Lower limb strength training for children with Spastic Diplegic Cerebral Palsy receiving Botulinum Neurotoxin Type-A: Outcome evaluations at all levels of the International Classification of Functioning, Disability and Health' utilised a multidimensional approach in the assessment of a combination of two common therapeutic interventions for children with Cerebral Palsy. This included assessments of muscle morphology using MRI, muscle strength, 3D gait analysis, functional ability, and activity, participation and quality of life. The home based, client focused strength training program was developed, administered and progressed by Sian, who is an Accredited Exercise Physiologist through Exercise and Sports Science Australia (ESSA).

Sian is currently a post doctoral fellow with the Australasian Cerebral Palsy Clinical Trials Network, based in Auckland New Zealand.
