My most recent book, Crossing the Water and Keeping the Faith, is a historical and ethnographic study of Haitian religion in immigrant communities, based on fieldwork in both Miami and Haiti. Where many studies of Haitian religion limit themselves to one faith, I and my co-author Terry Re explore Catholicism, Protestantism, and Vodou in conversation with one another, suggesting that despite the differences between these practices, the three faiths ultimately create a sense of unity, fulfillment, and self-worth in Haitian communities. With Carol Dutton Stepick I also recently wrote comprehensive review and revision of segmented assimilation theory. In general, my work focuses on the impacts of immigration on which I have written ten books and over 50 articles and book chapters.
