He arrived at Notre Dame in 2017 as a Postdoctoral Associate with the Cushwa Center for the Study of American Catholicism and still engages with the center as a faculty affiliate. He has been teaching in the Department of American Studies since 2019. His research explores the roles of religion and ideas in modern American culture. Cajka earned a PhD in modern American history from Boston College in 2017. His book, Follow Your Conscience: The Catholic Church and the Spirit of the Sixties, will be published with the University of Chicago Press in 2021.
