After completing a Bachelor of Science degree in Biology from Mount Allison University in 2004, Gillian graduated from Dalhousie University with a Bachelor of Science in Physiotherapy in 2007. She worked clinically for two years in private practice while completing a Master of Science degree in Rehabilitation Research. Following her MSc degree, Gillian obtained a PhD in Biomedical Engineering at Dalhousie University in 2013, where her research focused on developing prediction models for knee osteoarthritis progression based on gait biomechanics. 

In 2014 Gillian began a postdoctoral fellowship at the University of British Columbia in the Department of Physical Therapy. She worked there, while teaching Biomechanics and Topics in Human Nutrition at Douglas College until September 2016, when she began working at the University of the Fraser Valley full time.
