I am a critical geographer and environmental designer based at the University of Chicago, where I am affiliated faculty with the Committee on Environment, Geography, and Urbanization, Senior Research Associate in Global Political Ecology and Associate Director of the Urban Theory Lab. I work on the relationship between environment, technics, and empire, which I explore through writing, mapping, design, video, and other media. My most recent research focuses on oceanic formations and geographic imaginaries of US empire in the Pacific and Arctic, ranging from the mid-19th century into speculative near-futures. In 2016, I wrote an award-winning book with Pierre Bélanger, Ecologies of Power, published by MIT Press, on the logistical landscapes of global U.S. militarism beyond the battlefield. I completed my PhD in 2021 in the Department of Geography at the University of California, Berkeley, with a designated emphasis in Science and Technology Studies. My research has been supported by the National Science Foundation, Institute on Global Cooperation and Conflict, Peder Sather Center for Advanced Study, and UC Berkeley Bancroft Library Fellowship, among others. I hold degrees in Landscape Architecture (MLA, Harvard University Graduate School of Design), Human Rights, and Philosophy (BA, Columbia University). I grew up in the San Francisco Bay Area, on unceded Coast Miwok land, and currently live and work on the South Side of Chicago, homelands of the Niswi-mishkodewin (Council of the Three Fires)-- the Odawak (Odawa), Anishinaabeg (Ojibwe), and Bodéwadmiakiwen (Potawatomi).
