My research focuses primarily on cardiovascular health throughout the lifespan. My interests include the effects of childhood growth and development and adult aging on the cardiovascular system. My research also focuses on the detrimental impact of cardiovascular risk factors throughout the lifespan and the beneficial role of lifestyle factors at any age on cardiovascular health. I am also the director of the Brock Functional Inclusive Training (Bfit) Centre.  This facility serves as both a research and community-based exercise centre for individuals in Niagara. The Centre currently has exercise programs for healthy seniors (SeniorFit), individuals with cardiovascular disease (Heart Strong), spinal cord injury, Parkinson’s, multiple sclerosis, and amputees (Power Cord).
