As a Kosciuszko Foundation grantee at the Boisi Center, she is working on a book concerning the role of religion in the American public sphere. The book is designed to introduce Polish students to questions surrounding the relationship between church and state, religion and the public sphere, and religion and politics in the United States. It will present a history of religious pluralism, the development of American civil religion, an analysis of the role conservative and liberal churches intend to play in American politics, and the development of the American Religious Right. Napierala is also continuing her comparative studies concerning Polish and American Religious Right movements.
