Dai's Geospatial Research & Innovation Group

Dr. Dai’s Geospatial Research & Innovation Group (GRIG) applies advanced geospatial techniques and data science to address critical challenges in environment, public health, and transportation. Our research uncovers how the built environment, healthcare access, and neighborhood dynamics shape communities—driving solutions that improve planning, policy, and quality of life. 

We deliver advanced geospatial technologies and expertise to empower researchers, students, and communities in Metro Atlanta and beyond. Whether you are interested in joining our research team, exploring collaborations, or seeking geospatial services, we invite you to CONTACT US.

Our research is supported by leading global and national organizations, including the World Health Organization (WHO), the National Institutes of Health (NIH), the United States Department of Agriculture (USDA), the United States Geological Survey (USGS), the Robert Wood Johnson Foundation (RWJF), among others. Through collaboration spanning Asia, Europe, South America, North America, and Africa, we address critical challenges with worldwide impact. Learn more on OUR PROJECTS.

Dr. Dai and his colleagues developed the Urban Health Index toolkit (UHI) for the World Health Organization, an innovative tool that uses a single matrix to evaluate health disparities in cities. Download the Excel-based tool here. Access the full WHO-published report here.
