I am a medievalist whose main area of concentration is the 14th and 15th centuries. Besides teaching Chaucer, I teach the literature of King Arthur from its beginnings to the present day. Tolkien is a favorite of mine, especially since he was a medievalist. When I teach Tolkien, I teach about the medieval background to his major literary works such as The Lord of the Rings and The Hobbit. Other areas that I work in are literary theory and science fiction. What fascinates me about science fiction is how it helps us to ask all kinds of great questions about how life and the universe works, whether it’s religious, political, or philosophical questions. At present, I am working on a project to do with the Gawain-poet who wrote the excellent poem, Sir Gawain and the Green Knight.
