My laboratory performs translational research that integrates both molecular and behavioral studies. This innovative approach is necessary to discover an effective public health solution to prevent and manage conditions adversely impacted by sedentary living (aging, diabetes, obesity, some cancers, dementia, and cardiovascular disease). The goal is for a scalable solution that can most feasibly provide the metabolic benefits of a high duration of muscular activity for people living with poverty, pre-existing health conditions, or other reasons associated with excessive sedentary time.
