You can contact Joseph Nagy through his UCLA page HERE.

Prof. Nagy is a very interesting lecturer and is great at fielding questions. He has also written and edited several books, some of which you can see HERE.

And yes, Prof. Nagy is highly regarded among Celtic Studies scholars. When I was an undergrad majoring in Celtic Studies at the University of Toronto, Wisdom of the Outlaw and Conversing with Angels and Ancients were on our reading list. You could say he's one of the giants in our field. Got my fingers crossed that he says yes. *S*
