Diana Grigsby- Toussaint


Diana Grigsby-Toussaint is an Associate Professor of Behavioral and Social Sciences and Epidemiology at the Brown University School of Public Health. She also has appointments with the Population Studies Training Center and the Spatial Structures in the Social Sciences program at Brown.  As a social epidemiologist, her research seeks to capture complex processes in the food, social, and built environments to facilitate a better understanding of their influence on what has been coined the three pillars of health: diet, physical activity and sleep. Her work has involved explorations of access to green space and physical activity among preschoolers; the role natural amenities may play in sleep outcomes; and how green space may attenuate COVID-19 risk while accounting for public health measures. She is currently the PI of a National Institutes of Health (NIH) RO1 that is examining the influence of green space on mental health and sleep among elementary school children in Rhode Island.
