Kathleen Flake is associate professor of American religious history at Vanderbilt University. The "On Faith" panelist teaches courses in new religious movements and the relation between church and state in America. She researches the effect of politics on religion and the strategies by which religious communities maintain a sense of fidelity to an originating vision, while changing over time. Her recent book, "The Politics of American Religious Identity: the Seating of Reed Smoot, Mormon Apostle," addresses both questions in the context of twentieth-century Mormonism. Descended from Southern Mormon pioneers and Baptist dust bowl migrants who ended up in Arizona, she now lives in Nashville, and is a practicing Latter-day Saint. Prior to her appointment to Vanderbilt, she was a litigation attorney in Washington, D.C., representing the government in civil rights and professional liability cases.
