I am a community ecologist interested in how the composition and distribution of ecological communities are affected by species invasions, biotic interactions (e.g., competition, predation), biophysical feedbacks, and climate change. My research program uses a combination of observational data, experiments, and modeling to connect observed patterns of species distributions and community composition with underlying mechanisms. Understanding these mechanisms is necessary if we are to make robust predictions about how ecosystems and their communities will respond to change.
I am particularly interested in the importance of biotic interactions within ecological communities, and how this combines with climatic change and invasions to alter species composition and geographic distribution. With this in mind, I use experiments, extant datasets, and natural history to incorporate biotic interactions into models that predict the effects of climate change and invasions on species and their communities. I use a variety of approaches including: species distribution models (SDMs), population simulations, and time-series approaches. My work spans different ecosystems including coastal dunes, forests, rivers, and lakes.
As my research intersects ecology and the physical sciences, much of my work is interdisciplinary and collaborative. These collaborations advance scientific understanding in new ways that help inform conservation, management, and adaptation in an era of rapid global change.
