Julia went to St Hugh's College, Oxford where she studied English with a special emphasis on the medieval and the history of the language. Here, she first became fascinated with the way the English language has developed and the influences that have directed its development. She subsequently gained a PhD at the University of Reading, with an edition of a fifteenth century prose romance - "The Three Kings' Sons", which she still reckons would make a good film.
She has split her working life between writing and teaching. She has taught for both the Oxford universities and at some of the many American university programmes in Oxford. She now concentrates on the American colleges and summer schools for the Department of External Studies at the University of Oxford. Her numerous book titles include:-
