Dr. Jennifer Copeland’s primary research interest is the influence of physical activity and sedentary behaviour on health across the lifespan, with a particular focus on healthy ageing. Dr. Copeland address these issues through both experimental and intervention studies as well as through the analysis of large data sets. Dr. Copeland’s doctoral research focused on endocrine responses to exercise and continues some work in that area today. Through her collaborations, she has developed a strong interest in the role of physical activity in physiological resilience to social stress. Dr. Copeland is also interested in public health initiatives that promote physical activity.
