Research Statement

My research interests involve hunter-gatherer paleoecology and prehistory, especially the analysis of human- and climate-induced change in past faunal landscapes, and their implications for related aspects of human behavior, historical ecology, and modern conservation biology. The archaeofaunal record of past foraging behavior is the primary window through which I explore these issues; quantitative applications of foraging theory models to such records in western North America constitutes the core of my empirical work. In this context, I have analyzed late Quaternary archaeological and paleontological fish, bird, and mammal faunas from across the west. These substantive analyses reflect my general interest in the application of models from evolutionary ecology to the archaeological record of ancient human behavior. Ongoing projects involve the analysis of avian prey choice and patch use by ancient hunters of the San Francisco Bay area; Holocene climate change, artiodactyl population histories, and large game hunting patterns in California, Baja California, and the Great Basin; and ancient DNA tests for a proposed human-caused late Holocene population decline in California tule elk.
