I received my BA and MA from Simon Fraser University, where I researched the environmental history of Native herring fisheries in British Columbia. I completed doctoral studies at the University of California-Davis, developing fields in environmental history, American history, and world history. My first book, Vanishing America: Species Extinction, Racial Peril, and The Origins of Conservation (Harvard UP, 2016), uses discourses of extinction to explore connections between racial attitudes and environmental thought in late-nineteenth and early-twentieth-century America. I am presently an Associate Professor of Environmental History at NTU in Singapore, where I am researching the global history of human interactions with sharks in the twentieth century.
