MS. Sara Cornejo Zepeda

PhD Student in Geospatial Analytics

I am a geospatial analyst and environmental researcher focused on water systems, climate impacts, and urban resilience. I am passionate about bridging science and application, combining field data, geospatial tools, and visualization to better understand how infrastructure responds to environmental stressors. I am especially interested in making environmental data accessible to support better decisions in cities and communities.
