He holds a Ph.D. (1994) in Russian and comparative Slavonic linguistics. He will spend four months at Harvard (October 2005–January 2006) to work on two topics: "A History of the Ukrainian Language in Galicia, 1772–1849," and "The Language of the Cossacks." In the former, Moser will study the development of the Ukrainian language in Galicia, particularly the years leading up to the revolution of 1848–1849. In the latter, he will seek a greater understanding of the language of the hetmans by looking at their universals, letters, poems, and correspondence.
