My research interest lies in contributing to efforts to understand the demands of everyday activities and their impact on well-being, capacity for self-regulation, and cognitive performance. The overall demand of an activity can be measured by considering all its different types of demands including those mental, physical, emotional (e.g., frustration), and temporal (e.g., time pressure) in nature. These demands come with an associated physiological stress response, and as such there is a limit to the total amount of demands our bodies can experience. Whether or not activities are truly stressful or relaxing, physiologically, may depend on the demands required by them.

My current goals are to help advance measurement of activity demands through self-report, and in the future, to capture the physiological effects of the total demands placed on our bodies using smartphones and/or wearable technology. My goal is to develop tools that will provide metrics to help people determine if their everyday pattern of activities need to be adjusted (e.g., changing the number of high or low demand activities in which they engage) to improve or maintain well-being, capacity for self-regulation, and/or cognitive performance.
