Abby, go to www.princeton.edu/~religion/ and look at the short bio of Elaine Pagels; she's expert in the early CE gnostic literature, and probably on the biblical related literature, too. I saw her on a TV documentary about a week ago, and she's gotten older (probably a grandmother now), since the picture I got of her about 25 years ago, and is no longer the stunning beauty she was then (but still very good). Her husband, Hans, used to be (maybe still is) a freelance reseacher with some noteable books to his credit.
