I am interested in historical and synchronic linguistics, particularly in the Germanic and related Indo-European languages. I have taught courses here at the University of Washington in both the Linguistics Department, of which I am an adjunct member, and the Germanics Department. Namely, I have taught courses in Historical and Comparative Linguistics, Indo-European, History of the German Language, a survey of the Germanic languages, and the older Germanic languages: Old High German, Gothic, Old Saxon and Middle High German. I have taught similar courses as a guest professor at the University of Cologne, Princeton and the University of California at Berkeley. My research has been primarily in the early history of the germanics languages. At present, my colleague Charles Barrack and I are completing a book titled: An Introduction to Proto-Indo-European and the Early Indo-European Languages, which has been accepted for publication.
