His current book project, entitled The Spirit of Evangelicalism: Media, Markets, and Commercial Religion, traces the history of the evangelical book industry and its audience since the end of the nineteenth century, examining how evangelical ideas and identities have taken shape through commercial strategy and corporate initiative. Other current research subjects include the notion of non-profit status and the ideal of authorship. Since joining Brown's faculty in 2013, Professor Vaca has taught courses on topics including spirituality; money and media; religious freedom; and Christmas.
