Becoming 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.

My graduate training was completed at the University of Western Ontario. I received an MSc in Kinesiology (Neurovascular physiology) 2007 and a PhD in Medical Biophysics (The Impact of the Sympathetic NPY System on the Progression of breast cancer) in 2013. Prior to joining Laurier, I was a postdoctoral fellow at the Princess Margaret Cancer Center (Molecular Imaging) from 2013 to 2016 and at the University of Guelph (Department of Molecular and Cellular Biology) from 2016 to 2019.
My research interests focus on sympathetic neural regulation of the circulatory system at rest, during exercise and in diseased conditions. This research extends from molecular to systemic neurotransmitters/peptides induced responses.
Outside of the laboratory, my current pedagogical research interests include evaluating the utility of:
- digital learning platforms
- non-traditional assessment strategies
- problem based learning within the life sciences
- Wilfrid Laurier University Early Career Teaching Excellence Award nomination (2018, 2019)
- Dr. Alfred Jay Medical Biophysics Award (UWO, 2013)
