He is especially interested in Native responses to colonialism, the effects of disease on colonial encounters, and new ways of visualizing these processes through digital history. He has published a biography on Fray Junipero Serra, the principal founder of California's mission system, and a monograph on Indian life in the California missions, as well as numerous essays, a textbook, and two edited volumes. He is the general editor of the Early California Population Project and the Project Director for the Early California Cultural Atlas
