Research interests

My lab seeks to better understand how and why vascular disease is accelerated by complex blood flow (e.g., recirculation) and abnormal vascular wall properties. My lab is focused on three main lines of investigation:

• Control of complex blood flow and wall motion in conduit arteries and veins
• Impact of sedentary behaviour and exercise on vessel risk exposure
• Discovery of novel outcomes of vascular disease progression and severity

These areas are supported by an integrative physiology program that combines next-generation ultrasound imaging, human dose-response models, and exercise training interventions for a comprehensive understanding of vascular health.
