Bio: Jo Guldi is a historian whose interests range over the transition from pre-modern to modern societies. As a historian, she specializes in the study of infrastructure, land use, and capitalism. As a digital researcher, she has co-taught courses at the University of Chicago on the visualization of time, geoparsing, and other new methods applied to the study of long-term historical trends. Her first book, Roads to Power, tells the story of the infrastructure state and made abundant use of keyword text mining to understand interactions between strangers on the public street. Another project, the Spatial Humanities site, examines the “long spatial turn” that stamped the academic disciplines with a concern for landscape at the point of their formation. She is currently working on The Future of History, a book concerned with how digital methods impact the discipline of history-writing. Her next major research project, Participation Restored, employs text-mining over longue-duree data sets to tell the history of the ancient peasant commons, its enclosure, and its restitution through radical legal movements of the 19th and 20th centuries. Her blog, landscape.blogspot.com, documents some of her collaborations on big-data, visualization, and geo-parsing projects and the shared interests of digital researchers and the humanities.
