Greg Bratman.jpg

Dr. Gregory Bratman's work takes place at the nexus of psychology, public health and ecology, and is focused on investigating the ways in which the environment is associated with human well-being. He takes both empirical and theoretical approaches to understand how nature experience impacts cognitive function, mood, and emotion regulation, with an emphasis on people living in urban environments. He has also published reviews about the impacts of the environment on mental health, informed methods for integrating these effects into ecosystem service studies, and proposed ways in which this science can be put into practice to address health inequities that are disproportionately experienced by underserved communities. Dr. Bratman is the Doug Walker Endowed Professor at The University of Washington and a JPB Environmental Health Fellow through the Harvard T.H. Chan School of Public Health.
