Botanist with critter curiosity specializing in southwestern US flora, especially central Arizona, Mojave and Sonoran Deserts, and coastal southern California.

I work with federal agencies, botanical gardens, universities and consulting firms conducting floras, rare plant surveys and monitoring, and ecological research.

I have research interests in taxonomy and systematics (Physalis, Poaceae, Lamiaceae, others), plant-environment relationships and biogeography, evolution and biogeography of endemic and rare taxa, edaphic evolution, ethnobotany - specifically how humans have moved plants around historically and prehistorically, and riparian plant ecological processes and conservation.
