I grew up in Dundas, Ontario and received my undergraduate degree in Kinesiology from McMaster University (1999-2004). I then pursued a Master's degree in Human Kinetics at the University of Windsor under the supervision of Drs. Kenji Kenno and Jennifer Jakobi (2004-2006). After discovering a passion for research and teaching, I pursued a PhD in exercise nutrition at The University of Western Ontario under the supervision of Dr. Peter Lemon in the Exercise Nutrition Research Laboratory (2006-2010). Prior to joining Laurier, I completed a Post-doctoral Fellowship in the Department of Dietetics and Human Nutrition at McGill University under the supervision of Dr. Hope Weiler (2010-2012) and was an Assistant Professor in the Department of Kinesiology and Physical Education at the University of Lethbridge in Southern Alberta (2012-2014).
My research examines the effect of exercise intensity and sex on energy balance by measuring both energy expenditure and the regulation of energy intake. I am principally interested in the potential for exercise intensity to improve energy balance through its potential to alter appetite regulation and post-exercise metabolism. Current funded work in my laboratory is examining potential mechanisms involved in the effect of exercise on appetite-regulating gut hormones. In addition, I am also interested in the potential acute and chronic health benefits of different exercise modalities such as high-intensity interval training.
I am willing to supervise both undergraduate and graduate students in the areas of exercise physiology and exercise nutrition. I currently supervise 3 MKin students, with 2 more starting in the fall of 2017 as well as 2 undergraduate Honours Thesis students.
