I am a Senior Lecturer in Physiotherapy at Auckland University of Technology’s School of Clinical Sciences and Co-Director of the Rehabilitation Innovation Centre. My research focuses on innovation in rehabilitation clinical practice and the development of novel technologies to augment rehabilitation. I have 20 years’ clinical and leadership experience in community, rehabilitation and acute healthcare settings; primarily working with people with neurological conditions. In 2007 I completed my Masters of Health Science investigating neuromuscular fatigue in people with stroke, and in 2014 my Doctorate of Philosophy investigating the effects of different forms of exercise rehabilitation in people with stroke.

My research applies understanding of neurophysiology and motor control to the field of rehabilitation to inform the development of novel physical rehabilitation interventions, including rehabilitation technologies.
I am interested in unpacking patients’ and clinicians’ perspectives of rehabilitation in particular the constructs of intensity, volume, specificity and dose of rehabilitation activity.
As a Co-Director of the Rehabilitation Innovation Centre I have focused on developing new rehabilitation technologies as a vehicle for translating research to clinical practice. With a multidisciplinary team of Clinicians, Biomedical Engineers, Health Psychologists, Designers, Neuroscientists, Stroke Advisors and Commercialisation experts across national and international organisations we have worked to commercialise rehabilitation technologies including:
- A portable, robotic upper limb rehabilitation device
- A brain computer interface device for enhancing neuroplasticity during rehabilitation
- An accelerometry based behaviour change technology for increasing physical activity in rehabilitation.
Current Research Projects:
- The Intense Trial: Co-design to promote the intensity and dose of inpatient rehabilitation.
- Strength for Task Training: A novel locomotor rehabilitation intervention.
- Conceptualizing and understanding the experience of Flow in Rehabilitation.
- Excite-BCI: A brain computer interface to promote neural plasticity in people with stroke.
- BuzzNudge: Using accelerometry to promote upper limb activity in rehabilitation.
- RoboRover: A portable, robotic upper limb rehabilitation device.
- Characterising clinical reasoning in Ankle Foot Orthosis prescription.
- Exploring the kinematic, electromyographic and pedobarographic parameters of locomotor activities in the REX Robotic Exoskeleton.
- The feasibility, safety and acceptability of the REX robotic exoskeleton for physical activity and upper limb exercise in people with spinal cord injury.
