I am a plant population and community ecologist at Utah State University, where I have worked since 2006. I have two main lines of research: 1) Applied research on the impacts of climate change on plant populations and communities, and 2) more basic research on mechanisms of coexistence and patterns of species diversity. Much of my research relies heavily on statistical and mathematical models. I often fit those models to long-term data sets, some stretching as far back as the early 1900's.
