Alex Zahara is a PhD candidate studying geography at Memorial University in Canada. His research draws on critical northern studies, science and technology studies (STS), and waste studies to examine how uranium shapes social and material relations in northern Saskatchewan, Canada. Stories about uranium mining have informed how southern Canadians understand and engage with “the North”: depictions of untamed wilderness—amenable to resource extraction and colonial adventure—and of fragile ecosystems and indigenous populations inform the neocolonial present. For indigenous people living near abandoned uranium mines, contaminated landscapes physically impact on bodies and dictate spaces of social (human, nonhuman, and inhuman) relations. Ongoing protests over nuclear waste disposal sites show a refusal to accept techno-scientific safety narratives and highlight the anticolonial governing practices of self-determining indigenous communities. By focusing on political ecologies of matter, story, and risk, Alex examines uranium as “world making” in the Canadian subarctic. Alex’s thesis for his master’s degree in environmental studies (Queen’s University, 2015) examined issues of waste management in Iqaluit, Nunavut, including the politics of a summer-long dump fire. Prior to his graduate studies, he was a research intern in a biology lab at the University of Saskatchewan, where he worked on various scientific research projects analyzing the environmental impacts of PCBs, pesticides, and other pollutants. This toxicology work has been published in Environmental Toxicology and Chemistry and Environmental Science and Technology.
