Research
I study the determinants of species richness at all spatial scales, from the microcosm to the continent. I have used a variety of methods, including meta-analysis of floristic data, greenhouse microcosms, computer simulations, permanent plot data, and field experiments. Particular projects include an analysis of North American floras, analysis of ordination methods, studies on microcommunities emerging from soil seed banks, the flora of the Tallgrass Prairie Preserve, the vegetation of the Tallgrass Prairie Preserve, the distribution of Costa Rican rain forest trees, analysis of species-area curves, methods for extrapolating biodiversity, applications of fractal geometry, forest dynamics in an old-growth North Carolina forest, succession following catastrophic wind disturbance in Minnesota, and several others.

My two largest projects currently are the Floras of North America Project and the Plant Virus Biodiversity and Ecology project.
