Biography and education
Dr. Su Han is an Assistant Professor in the Department of Geography and Environmental Studies at Texas State University. She earned her Ph.D. in Geography through the joint doctoral program between San Diego State University and the University of California, Santa Barbara. She also holds an M.S. in Geography and Geographic Information Science from the University of Illinois at Urbana-Champaign. As an undergraduate at the University of North Carolina at Chapel Hill, she majored in Geography and minored in Computer Science.
Her research interests include spatial data science, social media analytics, health GIS, web-based GIS, GIS-based decision support systems, CyberGIS, cartography, geovisualization, geovisual analytics, and neighborhood dynamics. Her current research focuses on environmental justice and climate change, specifically exploring disparities in human mobility across different socioeconomic and demographic groups during heatwaves. Additionally, she investigates evacuation-related travel patterns during the Palisades and Eaton wildfires using millions of foot traffic data points collected from mobile apps. Her work also examines accessibility to shelters during wildfire events.
Dr. Han is also the core developer and maintainer of CyberGIS-Vis, an open-source software tool for interactive geospatial visualization and scalable visual analytics.
