Donna Freitas is Assistant Professor of Religion at Boston University. The "On Faith" panelist's literary and academic focus is the struggle of belonging and alienation with regard to faith, particularly among young adults, and especially young women. Freitas asks the 'Big Questions' (Why are we here anyway?) and delights in discovering the many forums in which to dabble with faith, religion, spirituality, and gender. A Catholic, she also is an ardent feminist. Her books include Becoming a Goddess of Inner Poise: Spirituality for the Bridget Jones in All of Us, (2005) and Save the Date: A Spirituality of Dating, Love, Dinner & the Divine. Freitas' most recent book project is Sex and the Soul, set for publication in 2007. It is based on a national study about the influence of sexuality and romantic relationships on the spiritual identities of America 's college students. Freitas' first novel, The Possibilities of Sainthood, which is about 15-year Antonia Lucia Labella, who aspires to become the first official living saint in Catholic history, is due for publication in 2008.
