Being a Golden Hawk means more than just cheering on our (really good) varsity teams – it means being a student who cares about your community, who works hard in the classroom, and who takes advantage of all the learning opportunities that can happen outside the classroom, too.
I received my PhD in Biology from York University in 2005 and my MSc in Kinesiology from York University in 1998.
Prior to joining Laurier, I completed a postdoctoral fellowship at the Spinal Cord Research Centre at the University of Manitoba (2005-2008).
Research Interests / Ongoing Projects
The purpose of my Natural Sciences and Engineering Research Council funded program of research is to determine how spinal reflex circuits integrate input from the brain and peripheral sensory receptors to maintain optimal voluntary drive to muscle during fatigue.
I am also interested in the inhibitory pathways that modulate the excitability of the primary motor cortex during fatigue. This research is significant because until we understand the central mechanisms that modulate muscle output in healthy people, we cannot fully understand the mechanisms of impaired motor function in injury, aging and disease.
Awards and Achievements
Natural Sciences and Engineering Research Council Discovery Grant: Spinal and Supraspinal Mechanisms of Fatigue.
Student Opportunities / Supervising
I have research assistantships opportunities for undergraduate and graduate students interested in the neural control of movement.
I am willing to supervise graduate students interested in the cortical and spinal adaptations to exercise, neuromuscular fatigue and concussion.
