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 program aims to better understand how physical activity/exercise contributes to the regulation of appetite, its subsequent effects on energy intake, and its overall role in reducing positive energy balance and fat mass. Current funded work examines the regulation of energy intake via the specific mechanisms involved in how exercise alters appetite through the integration of peripheral signals with either orexigenic (appetite-stimulating) or anorexigenic (appetite-inhibiting) properties. Overall, we are interested in the potential for exercise intensity to improve energy balance through alterations in appetite regulation and post-exercise metabolism. With my research interests in nutrition/exercise physiology, I am also interested in the effect of different nutritional supplements or feeding strategies on exercise metabolism.

Leading an active research program allows me to pursue one of my true passions, mentoring students. My trainees receive training in nutrition, exercise physiology, and biochemistry. My goal is to ensure they are prepared to contribute in meaningful ways to their career progression. As an advisor I aim to create a collegial environment that grows critical thinking, independence, and teamwork as my students can work independently and/or excel as a team. I challenge my students to identify an issue, generate an appropriate research question, develop their ability to design the methodology, collect the data, and finally analyze and interpret the acquired data.
I currently supervise 2 Doctoral, 1 Masters, and 1 undergraduate Honours Thesis students. I am always willing to supervise both undergraduate and graduate students in the areas of exercise physiology and exercise nutrition. Contact Dr. Hazell if you have an interest in any of our work. Please note you do not have to develop your own research question before reaching out.
