My interests include the phylogenetic systematics and biogeography of the biodiverse legume plant family (Fabaceae or Leguminosae), including the cultivated species. Because legumes are abundant and diverse in highly seasonal environments, I am interested in the study of patterns of plant biodiversity in the North American sagebrush steppe and the seasonally dry neotropical forests and woodlands where succulent plant groups such as cacti, euphorbs, bromeliads, agaves, and aesclepiads are also common. I use community phylogenetic approaches to integrate systematics and phylogeny with community ecology. This approach provides insights into how patterns of alpha and beta phylogenetic diversity are shaped by climate, disturbance, and other abiotic and biotic variables. Such research potentially assists reclamation and restoration efforts in highly seasonal vegetation. I am also interested in the flora of western North America, including the biodiversity of the sagebrush steppe and of graminoid species. Graminoids dominate open arid and semi-arid regions of western North America and because grass species thrive with humans, patterns of grass biodiversity typically reflect the history of human impacts on arid vegetation. My interests happily coincide with my teaching responsibilities, which include plant systematics and agrostology.
