Ken has written extensively on American landscape history. He is best known for his book Shadowed Ground: America’s Landscapes of Violence and Tragedy that focuses on how violence and tragedy are marked and memorialized. This work continues to influence debate over sites of violence and tragedy in the U.S. and all around the world. Of special interest is how memory and memory practice is spatialized to particular places and spaces.
Ken’s other major works in cultural geography include the co-edited Re-reading Cultural Geography and the co-authored Narrating Space/Spatializing Narrative. He am also very interested in the development of national commemorative traditions in the U.S. and Europe, racialized landscapes, and the commemoration African American, Chinese American, Japanese American and Jewish American heritage sites in the United States, as well as heritage tourism, and historical GIS.
