I am an environmental anthropologist and ethnographer. My research examines how human-produced excesses—bodily, agricultural, and industrial—have come to shape the ecologies of the Anthropocene, both in Amazonia and the American Midwest. My latest project, funded by the Wenner-Gren Foundation, specifically investigates the use biosolids (i.e., treated sewage sludge) for industrial agricultural production, urban gardening, landscaping, and ecological restoration in the United States. My research has appeared in such scholarly journals as American Anthropologist, Current Anthropology, Human Ecology, and Human Organization as well as popular outlets including The Atlantic, The Conversation, and SAPIENS. I am also author of the recent book Amazonia in the Anthropocene: People, Soils, Plants, Forests.
