RYAN EDWARDS (Ph.D. Cornell University) is an environmental historian of Argentina and the broader Southern Cone, whose work takes a spatial and geographical approach to the study of incarceration. During his two years with PLAS, Edwards taught courses on environmental history and the history of science and technology in Latin America, as well as prison studies across the Americas. In his final term, he was fortunate to work with the Freshman Seminars program and Learning Across Borders (LABs) to design a travel course to Patagonia, for which he was awarded a digital humanities seed grant and worked with the McGraw Center for Teaching and Learning -- though due to COVID-19, the travel component was canceled. Princeton provided Edwards with the time and resources to advance his scholarship, which included presentations at PLAS and the Latin American Studies Association, and work with the Latin American and Caribbean Workshop run by graduate students in the history department. He also participated in workshops on Rethinking the Penal Colony at the National Justice Museum in Nottingham, and the History of Modern Migration to and in the Americas at Harvard, as well as the American Historical Association annual conference where he was awarded an honorable mention for the Vanderwood Prize by the Conference on Latin American History. Utilizing the vast collection in Firestone Library, Edwards published book reviews in the Hispanic American Historical Review and the Bulletin of Latin American Research, and completed revisions for his book manuscript, A Carceral Ecology, which is forthcoming with the University of California Press. Edwards also worked closely with the Historic Maps Collection and Digital Maps and GIS Center in order to produce original maps for his manuscript. At the end of the PLAS fellowship, Edwards accepted a position as the content writer for the geospatial project management company, Unearth Labs.
