I am an interdisciplinary scholar of American culture with specific interests and training in African American culture, including music, television, and literature. I am the author of three books, most recently "It's Been Beautiful": Soul! and Black Power TV (Duke University Press, 2015). In general my work has been concerned with the cultural agency of marginalized subjects. This concern goes back to my first book, Crossing the Line (Duke UP, 2000), about literary representations of racial passing, as well as my 2007 Rosetta Tharpe biography Shout, Sister, Shout! (Beacon Press). It also threads through my published research on popular music, from Motown girl groups to "girly" bands. I am also interested in cultural memory, and have explored this this topic in a 2020 article in Feminist Media Studies, “’A queer black woman invented rock-and-roll’: Rosetta Tharpe, Memes, and Memory Practices in the Digital Age.” I have co-edited the Journal of Popular Music Studies and Bloomsbury’s 33-1/3 series of books on record albums. My work has been supported by fellowships from the Guggenheim Foundation and the National Endowment for the Humanities. My current project is a biography of the children’s musician Ella Jenkins.
