Center for Geospatial Analytics

Ryan uses geospatial analytics to study ecohydrology in both natural and human-modified ecosystems and works on environmental issues that have disproportionate impacts on American Indian communities. He develops modeling approaches to understand plant water use in the northern Rocky Mountains, runoff generation in the southern Appalachian Mountains, salinization of coastal environments of North Carolina and climate change impacts on waters of cultural significance to the Lumbee Tribe. Other interests include the geospatial dynamics of processes such as the spread of mountain pine beetle and the distribution of soil microbes involved in methane cycling.

Ryan uses remote sensing data to understand dynamic processes in natural and human-modified systems.
