My interests lie at the intersection of community ecology, macroecology, and biogeography but are grounded in collections-based research. Part of my work examines the basic community ecology of bats and rodents in Paraguay, California. Louisiana, New Mexico and Texas, in particular the effects of species environment interactions, dispersal, seasonality and competition on the structure of communities. I use morphometric approaches to characterize community structure, construct phenotypic measures of biodiversity and to better understand the relationship between form and function as it pertains to the ecology of organisms. I am also interested in the mechanistic bases of broad-scale patterns in the structure and diversity of communities and how to use this information to better conserve the world's biota.
