I'm an ecologist interested in understanding the drivers of spatial behavioral processes such as movement and habitat selection. I’m also interested in determining how these processes scale up to affect the demography and distribution of multiple sympatric species, and how these patterns then influence broader-scale patterns. In doing so, my research makes heavy use of spatial data, including GPS telemetry, and frequently involves developing quantitative approaches.
