Photo: Professor Contact info Email: xyao@uga.edu Office: 212C GG Building Phone Number: 706-583-0326 Research Interests: Geospatial data science: GIS, spatial statistics, machine learning, network analysis, Geovisaulization Subject areas of focus: Urban Transportation, Public Health CV: CV-Yao-Short_1.pdf (129.04 KB) Dr. Yao is a professor of Geography at the University of Georgia. As a geospatial data scientist, her research interests focus on geospatial techniques ranging from GIS, spatial statistics, machine learning methods, network analysis, and geovisualization. With domain interests in urban transportation and public health, she also applies geospatial techniques to study various urban and health problems. Dr. Yao is a past chair and current vice-chair of the ICA (International Cartographic Association) commission on Geospatial Analysis and Modeling. She is also the President-Elect of the Cartography and Geographic Information Society (CaGIS). Dr. Yao is always happy to recruit promising graduate students interested in developing and/or applying geospatial analytical techniques to study urban or health problems.
