My research focuses on gaining a better understanding of how the human brain is able to plan and execute body movements. We study this broad question in both healthy participants as well as in patients with traumatic brain injury (TBI) due to sports concussion or intimate partner violence. For this purpose, we use a suite of state-of-the-art equipment including the following:
- B·KIN KINARM system
- Northern Digital 3D motion capture
- Magstim transcranial magnetic stimulation
- Spencer Technologies transcranial Doppler ultrasound
- Finopres automated blood pressure monitoring
For our basic science research, we address questions related to the predictive processes underlying motor planning and how they are implemented in the brain. For the clinically oriented research, we are focusing on the cerebrovascular, sensorimotor, neurocognitive and blood biomarker impacts of TBI following concussion. We make use of behavioural experiments to address these issues and examine how the resulting deficits are related to changes in the underlying physiology and microstructural integrity in the brain. Finally, we use our basic and clinical findings to drive applied research aimed at better understanding TBI in the context of intimate partner violence (see our recent TEDx Kelowna talk on this topic).
