Professor Elukin teaches courses in medieval history, Jewish studies, historiography, and the history of the book. He is particularly interested in Jewish-Christian relations, the evolution of the Bible, the history of reading practices, philosophies of history, and various aspects of medieval society, including the Crusades, chivalry, English law and government, and the meaning of the Middle Ages for contemporary culture. He is currently writing a book about the history of the idea of a unitary "Jewish People."  He seeks to engage students in a dialogue about strategies to recover the lived experience of the past and to see how the events of the pre-modern world still shape our lives. He challenges students to become historically minded people through the close reading and interpretation of primary sources. He emphasizes the centrality of critical thinking and writing in a liberal arts education.
