Dr. Yao is a professor in 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, location-based big data analytics, and geovisualization. With domain interests in cities, human dynamics, and public health, she applies geospatial techniques to study various urban and health problems.   

Dr. Yao is an internationally known scholar in GIScience. She has been chairing the ICA (international cartographic association) commission on Geospatial Analysis and Modeling and has co-organized a series of professional meetings in that capacity. She is currently President-Elect of the Cartography and Geographic Information Society (CaGIS), a professional society that supports research, education, and practices of geospatial information and techniques. She also serves on the board of directors of the UCGIS (university consortium for geographic information science).

Dr. Yao is always happy to recruit promising graduate students who are interested in applying geospatial analytical techniques to study urban or health problems.

Education:
  • Ph.D , University at Buffalo, State University of New York
  • MSc., ITC (now Twente University), the Netherlands
  • B.S.,  Wuhan University, China
