RESEARCH AND TEACHING AREAS

My research and teaching 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 damage to the brain due to a variety of injuries – most recently, our focus has been on concussion. For this purpose, we use a suite of state-of-the-art equipment including the following:

For our basic science research, we address questions related to the coordination between the eyes and hand, the interaction between cognitive/attention factors and motor output, and the predictive processes underlying motor planning and how they are implemented in the brain. For the clinically oriented research, we are currently focusing on the sensorimotor and neurocognitive deficits 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 through support from the STAR Initiative.
