My interest in metabolism began as a competitive distance runner as I became fascinated with trying to understand how the body produced energy to fuel exercise. I was first introduced to research as an undergraduate summer student working in the laboratory of Dr. Martin Gibala at McMaster University and was quickly hooked. After pursuing an MSc degree at the University of Saskatchewan focusing on sport nutrition I returned to McMaster to complete my PhD focusing on muscle mitochondrial adaptations to exercise in healthy humans and individuals with type 2 diabetes. These experiences gave me a strong background in human exercise physiology and metabolism. In my postdoctoral fellowship at UBC I explored how metabolic disruptions associated with obesity and type 2 diabetes (e.g., high glucose, hyperlipidemia) impacted inflammatory activation of isolated cells. In my current lab we combine all of these approaches to understand how the metabolic disruptions that characterize type 2 diabetes affect cellular inflammation and explore how different exercise and nutritional strategies can be used to reduce inflammation and improve overall cardiometabolic health.

Obesity, insulin resistance (prediabetes), and type 2 diabetes are interrelated disorders characterized by progressively deteriorating metabolic health. Metabolic impairments in these conditions lead to many negative health consequences, including increased risk of cardiovascular disease and cognitive decline. Research in the Exercise Metabolism and Inflammation Laboratory (EMIL) is focused on: 1) Understanding the mechanisms, and systemic consequences, of chronic low-grade inflammation; and 2) Determining how different exercise strategies impact cardiometabolic health and inflammatory status in individuals with, and at risk for, type 2 diabetes.

We utilize a translational approach, where in vivo studies in humans with type 2 diabetes guide cell culture experiments designed to understand molecular mechanisms, and vice versa.

In our human exercise physiology laboratory located in the Arts Building we have a metabolic cart, vascular ultrasound equipment, treadmill, cycle ergometers, elliptical trainer, resistance training equipment, and a medical procedures area which enable us to conduct studies ranging from acute exercise manipulations to clinical exercise trials with metabolic measurements.

In our cellular and molecular laboratory located in the adjacent Arts and Science Building, we have a full cell culture suite, Miltenyi MACSQuant(R) flow cytometer, MagPIX(R) multiplex reader, real-time PCR machine, multi-function plate reader, and western blot equipment.

Key experimental techniques utilized include continuous glucose monitoring, flow-mediated dilation, peripheral blood mononuclear cell (PBMC) isolation/culture, and multi-colour flow cytometry.

At the undergraduate level, I teach HMKN 313 – Exercise Metabolism and supervise students in HMKN 499 Research Practicum.
