Leslie Ries is an ecologist who focuses on patterns at both medium and large scales. She has worked both in the fields of landscape ecology and biogeography with her focus mainly on butterflies. Her current research focuses on large-scale patterns. She explores underlying mechanisms using laboratory studies of caterpillar growth and development based on different temperature regimes. She then studies these patterns across ranges using large databases, mostly originating from citizen science monitoring networks. Citizen science greatly expands the scale at which we can collect data and thus explore problems and solutions that are increasingly global in nature. Ries focuses on several facets of citizen-science, including the use of these data to answer large-scale ecological questions, especially those related to climate and land cover; developing statistical tools to extract the most robust information from the data; designing systems to support data management, visualization, and sharing; and developing “knowledge” databases that compile life history and other trait data to enrich multi-species analyses. In addition to carrying out and enabling large-scale ecological research, Ries has also been working on methods to integrate big-data approaches into undergraduate education, and she is also increasingly interested in informal education opportunities as well.
