I am a sport and exercise scientist and former professional and international rugby player, specialising in oxygen transport, muscle physiology, and brain health in contact sports. My research applies and develops near-infrared spectroscopy (NIRS/fNIRS) to study oxygen utilisation, neurovascular function, and sport-related concussion. I have published 25+ peer-reviewed articles across elite sport, clinical exercise physiology, and methodological validation, with cited work in sport concussion, sprint interval cycling, underwater NIRS validation, and portable NIRS applications. My current projects use fNIRS to investigate concussion and neurophysiological responses to head impacts in youth and amateur athletes.
