Cartography & Historical GIS

GIS Librarian and Developer

I create interactive maps, digital atlases, and geospatial tools that bring archival materials into conversation with the landscapes they document. My work focuses on the intersection of GIS, libraries, and digital scholarship, developing new approaches for making historical and contemporary geospatial data accessible, discoverable, and engaging.
