Incumbent of the Sol Rosenbloom Chair of Jewish History.
The main field of research and teaching at the University has been the early modern history; Jewish thought in the 16th century; History of Antisemitism; Jewish history under the National-Socialist Rule; Christian-Jewish relations from the 16th to the 20th century.
The central effort in scholarly work has been to create a primary base for research on the history of the Jews under the National-Socialist rule and to develop scientific criteria which would make it possible to integrate this central topic in Jewish and Universal history of the Twentieth Century.
