Professor Kenny's principal area of research and teaching is the history of American immigration, labor, and global migration. He has written several books on these subjects. Making Sense of the Molly Maguires examines how traditions of Irish agrarian protest were translated into an American industrial setting. The American Irish: A History offers a survey of the field since 1700. Peaceable Kingdom Lost analyzes the unraveling of William Penn’s vision of harmonious co-existence for Native Americans and European colonists. Kenny’s most recent book, Diaspora: A Very Short introduction, examines the origins, meaning, and utility of a central concept in the study of migration, with particular reference to Jewish, African, Irish, and Asian history. He is currently researching the intersection of immigration history with slavery from the American Revolution through Reconstruction.
