Patrick McHaffie joined the faculty at DePaul University in 1996 after academic appointments at West Virginia University, Dartmouth College, and West Georgia College. During the 1980's he served with the Kentucky Geological Survey where he conducted environmental research related to coal mining, directed the National Cartographic Information Center affiliate office, and coordinated the State Topographic Mapping Program. His research interests and publication history include the social history of cartography and GIS, the cartographic labor process, cartographic ethics, the geography of education spending, Appalachian social geography, and the social construction of the global. He currently is completing a study of highway planning in Chicago during the cold war. His work has been supported by grants from the National Science Foundation, History of Cartography Project (University of Wisconsin), and the University Research and Quality of Instruction Councils (DePaul University), and he holds a GISP certification.
