After earning a BA in geography from Ohio State University, Hudson was awarded a Fulbright Fellowship to conduct independent research at the University of Toronto, where he studied the inequity of Toronto’s waste exports to Michigan and southwest Ontario. At Gallatin, his concentration was political ecology and ethnographic film, and his research focused on the geographies of waste, value and disposability. A gallery of his photographs and information on his research can be found on his website, Geographies of Waste. Gallatin offered him a unique opportunity to integrate his visual interests into his social and scientific interests. Hudson was awarded a National Science Foundation Graduate Research Fellowship, which provides three years of support to graduate students studying science, technology, engineering, and mathematics. For his thesis project, he studied discourses of humans-as-waste, focusing specifically on how the Khmer Rouge justified acts of violence by reducing their enemies to a condition of waste.
