Hi! I'm Olivia

Olivia Zhang

Geography + Data Science Student at University of Florida

Passionate about how data storytelling, geographic information systems (GIS), and design can help us address climate change in an equitable and community-centered way, I study data science and geography with a certificate in geographic artificial intelligence at the University of Florida. Whether it’s designing maps, visualizing data, or building apps, I love to embrace creativity in everything I do. I am passionate about geospatial data science and technology for social good because of the endless opportunities to build connections and share stories.
