Research

Gavin Williams has extensive clinical research experience in outcome measurement following traumatic brain injury.
His doctoral thesis was on the development of the High-level Mobility Assessment Tool (HiMAT) for traumatic brain injury.

Gavin lectures at several Australian universities and presents his research at conferences around Australia and overseas.
He is an expert in retraining walking and running following neurological injury, and how these mobility problems are measured.
